&lt;div&gt;&amp;lt;span style=&amp;quot;font-size:130%;font-family:serif&amp;quot;&amp;gt;The Collapsible Project&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The goal of this project is to gather strategies, skills, disciplines, technologies, ideas, designs and critical thought in an effort to help prepare communities big and small for a time of great upheaval, an era of collapses (plural). It is not a submission to &#039;The Collapse&#039; and nor does it seek to romanticise an end times. Within this frame, individual-centered survivalist and prepper cultures are not encouraged, while we identify that both hold much that may be of use to communities facing tough times.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;In contributing to this wiki you:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
*    identify that we face not some future Collapse, but are already in the midst of multiple converging collapses.&lt;br /&gt;
*    recognise that the climate and extinction crises are due to the stresses our growth-addicted civilisation has placed on the Planet, and with that comes consequences for all alive.&lt;br /&gt;
*    understand that species extinction and a changed climate can not be undone, that we are already locked in for decades of consequences regardless of any mitigating steps made today.&lt;br /&gt;
*    understand that many communities are already enduring significant and sudden changes, and that we have much to learn from them.&lt;br /&gt;
*    believe that openly discussing and addressing the challenges we face is not &#039;negative&#039;, nor pessimistic, but essential to overcoming them.&lt;br /&gt;
*    understand that environmental defense and biome conservation today is crucial for our survival tomorrow.&lt;br /&gt;
*    recognise that socio-political and geo-political tensions are both expressions and major drivers within collapse.&lt;br /&gt;
*    recognise that true resilience means togetherness, and that strong communities are built atop a commitment to inclusivity.&lt;br /&gt;
*    honestly think tardigrades are amazing, not only because they are collapsible.&lt;br /&gt;
&lt;br /&gt;

== About this wiki ==&lt;br /&gt;
&lt;br /&gt;
This wiki exists as a collaborative notepad to collect and organise content for the Collapsible project, with a social media tentacle at the Mastodon instance at [https://collapsible.systems Collapsible.Systems]. It was launched on September 1, 2023. We are aiming to create a &#039;real&#039; wiki, with useful articles and conforming to a common editorial style, a &#039;collapsipedia&#039;. For this a domain has already been registered. &lt;br /&gt;
&lt;br /&gt;
The wiki will be built primarily as an online archive, but with offline networking applications in mind. A core outcome target is for the entire wiki to be served wirelessly (WLAN, single cell base station, packet radio) and over Ethernet from small low powered computers. PDF, e-pub and print-on-demand outcomes will also be explored. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Unlike other wikis that solely focus on sustainability or lone prepping, the Collapsible Wiki widens its scope to a holistic view on resilience, from organisational systems to disaster preparedness, radio communications, &#039;permacomputing&#039;, medicine and climate resilient cropping.&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
This work will be done in English, translated into other languages where translators are available.&lt;br /&gt;
&lt;br /&gt;
For the time being the priority is to gather all the external resources we can into one place (this wiki), using our Mastodon community as a sort of knowledge harvester.&lt;br /&gt;
&lt;br /&gt;
==Categories==&lt;br /&gt;
&lt;br /&gt;
This section is primarily here for mobile users, so they can reach the category list without the sidebar.&lt;br /&gt;

If you want to practice your wiki editing chops, try the [[Sandpit|Sandpit.]]&lt;br /&gt;
&lt;br /&gt;
Please note that &#039;&#039;Main Page&#039;&#039; is protected, as we need to communicate the basics here, and ensure everything is clear. If you have some suggestions, please add them in the Discussion tab for this page.&lt;br /&gt;
&lt;br /&gt;
As for the rest of the wiki, it&#039;s all open to editors in accordance with the same [https://collapsible.systems/about rules of the Mastodon instance].&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;This wiki is a collective effort. It belongs to its contributors.&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
=== Scope ===&lt;br /&gt;
&lt;br /&gt;
Rather than write detailed HOWTOs or get into extreme detail, the wiki should aim to provide &#039;&#039;helpful overviews&#039;&#039; to raise literacy, seed confidence, and get folk started on their preparation projects.&lt;br /&gt;
&lt;br /&gt;
The initial goal however is just to collect as many helpful resources here as possible for each section. That process can be really rough for now. If you just have links and don&#039;t know where to put them, just give them a quick title/descrip and drop them in the [[linkdump|Link Dump]]. That said, enthusiastic editors should feel free to flesh out articles and/or write up detailed notes, creating pages as needed. &lt;br /&gt;
&lt;br /&gt;
Before creating a new page, and for each contribution, editors are encouraged to check their entries for &#039;&#039;&#039;&#039;&#039;Utility&#039;&#039;&#039;&#039;&#039; (is the information useful, can it be applied?), &#039;&#039;&#039;&#039;&#039;Relevance&#039;&#039;&#039;&#039;&#039; (does it speak to the Collapsible frame?), &#039;&#039;&#039;&#039;&#039;Inclusivity&#039;&#039;&#039;&#039;&#039; (does it assume a particular audience, leaving out others?), &#039;&#039;&#039;&#039;&#039;Uniqueness&#039;&#039;&#039;&#039;&#039; (can it be found elsewhere in the wiki?), &#039;&#039;&#039;&#039;&#039;Accessibility&#039;&#039;&#039;&#039;&#039; (can it be understood without  prior knowledge, or with knowledge provided in situ?) and &#039;&#039;&#039;&#039;&#039;Region&#039;&#039;&#039;&#039;&#039; (does it assume a particular region to have relevance?).&lt;br /&gt;
&lt;br /&gt;
=== Style ===&lt;br /&gt;
&lt;br /&gt;
Please see [[Style guide|this attempt at a style guide]] before creating your first page. Rather than creating pages in the structure Category/Page, just create a new page, take note of it, and link to it under the relevant section (click on the Link symbol in the editor and enter the Page title). &lt;br /&gt;
&lt;br /&gt;
=== Create a new page ===&lt;br /&gt;
&lt;br /&gt;
New pages can be created by typing the name of a non-existent page after the &#039;&#039;&#039;index.php/&#039;&#039;&#039; in URL bar, or using the below form:&lt;br /&gt;
&lt;br /&gt;
{{#createpage:|new page name here}}&lt;br /&gt;
&lt;br /&gt;
If you want to create a page directly in the URL bar whose name has spaces, for instance a page titled &#039;&#039;Irrigation systems&#039;&#039;, you can &lt;br /&gt;
use underscores to reference spaces, like so:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;wiki.collapsible.systems/w/index.php/Irrigation_systems&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
=== Bot trap ===&lt;br /&gt;
&lt;br /&gt;
Because LLMs are scraping this site, a trap has been placed here so that they waste their time rather than scraping the pages here written by people.&lt;br /&gt;

Before creating a new page, and for each contribution, editors are encouraged to check their entries for &#039;&#039;&#039;&#039;&#039;Utility&#039;&#039;&#039;&#039;&#039; (is the information useful, can it be applied?), &#039;&#039;&#039;&#039;&#039;Relevance&#039;&#039;&#039;&#039;&#039; (does it speak to the Collapsible frame?), &#039;&#039;&#039;&#039;&#039;Inclusivity&#039;&#039;&#039;&#039;&#039; (does it assume a particular audience, leaving out others?), &#039;&#039;&#039;&#039;&#039;Uniqueness&#039;&#039;&#039;&#039;&#039; (can it be found elsewhere in the wiki?), &#039;&#039;&#039;&#039;&#039;Accessibility&#039;&#039;&#039;&#039;&#039; (can it be understood without  prior knowledge, or with knowledge provided in situ?) and &#039;&#039;&#039;&#039;&#039;Region&#039;&#039;&#039;&#039;&#039; (does it assume a particular region to have relevance?).&lt;br /&gt;
&lt;br /&gt;
=== Style ===&lt;br /&gt;
&lt;br /&gt;
Please see [[Style guide|this attempt at a style guide]] before creating your first page. Rather than creating pages in the structure Category/Page, just create a new page, take note of it, and link to it under the relevant section (click on the Link symbol in the editor and enter the Page title). &lt;br /&gt;
&lt;br /&gt;
=== Create a new page ===&lt;br /&gt;
&lt;br /&gt;
New pages can be created by typing the name of a non-existent page after the &#039;&#039;&#039;index.php/&#039;&#039;&#039; in URL bar, or using the below form:&lt;br /&gt;
&lt;br /&gt;
{{#createpage:|new page name here}}&lt;br /&gt;
&lt;br /&gt;
If you want to create a page directly in the URL bar whose name has spaces, for instance a page titled &#039;&#039;Irrigation systems&#039;&#039;, you can &lt;br /&gt;
use underscores to reference spaces, like so:&lt;br /&gt;
&lt;br /&gt;

&lt;div&gt;Permacomputing is both a concept and a community of practice oriented around issues of [[resilience]] and regenerativity in computer and network technology inspired by permaculture.&lt;br /&gt;
&lt;br /&gt;
In a time where computing epitomizes [[industrial waste]], permacomputing encourages the maximizing of hardware lifespans, minimizing energy use and focusing on the use of already available computational resources. We do this we want to find out how we can practice good relations with the Earth by learning from ecological systems to leverage and re-center existing technologies and practices. We are also interested in investigating what a permacomputing way of life could be, and what sort of transformative computational culture and aesthetics it could bring forward.&lt;br /&gt;
&lt;br /&gt;
Create low-power systems that strengthens the biosphere and use the wide-area network sparingly. Minimize the use of artificial energy, fossil fuels and mineral resources. Don&#039;t create systems that obfuscate waste.&lt;br /&gt;

&lt;div&gt;===What to do after an earthquake===&lt;br /&gt;
&lt;br /&gt;
* Expect aftershocks and remember to drop, cover and hold.&lt;br /&gt;
* Do not run outside. It is frightening to stay in a building immediately after an earthquake, but it is much safer than going outside. An earthquake is not like a fire. You do not have to evacuate a building straight away unless it is showing obvious signs of distress or you are in a tsunami evacuation zone.&lt;br /&gt;
* Look after yourself and get first aid if necessary. Help others if you can.&lt;br /&gt;
* Assess your home or workplace for damage. If the building appears unsafe get everyone out. Use the stairs, not an elevator and when outside, watch out for fallen power lines or broken gas lines. Stay out of damaged areas.&lt;br /&gt;
* Turn off water, electricity and gas if advised to. If you smell gas or hear a blowing or hissing noise, open a window, get everyone out quickly and turn off the gas if you can.&lt;br /&gt;
* If you see sparks, broken wires or evidence of electrical system damage, turn off the electricity at the main fuse box if it is safe to do so.&lt;br /&gt;
* Look for and extinguish small fires if it is safe to do so. Fire is a significant hazard following earthquakes.&lt;br /&gt;
* If you can, put on protective clothing that covers your arms and legs, and sturdy footwear. This is to protect yourself from injury by broken objects.&lt;br /&gt;
* If you are in a store, unfamiliar commercial building or on public transport, follow the instructions of those in charge.&lt;br /&gt;
* Listen to the radio for updated emergency information and instructions.&lt;br /&gt;
* Do not overload phone lines with non-emergency calls. Use social media (if online) or text messages, or a walkie-talkie or Meshtastic node instead of calling to keep phone lines clear for emergency calls.&lt;br /&gt;
* Help people who require special assistance – infants, elderly people, those without transportation, families who may need additional help, people with disabilities and the people who care for them. &lt;br /&gt;
* Keep control of your pets. Protect them from hazards and protect other people from your animals.&lt;br /&gt;
* Check on your neighbours and anyone who might need your help. &amp;lt;ref&amp;gt;https://www.civildefence.govt.nz/resources/what-to-do-after-an-earthquake&amp;lt;/ref&amp;gt; &amp;lt;ref&amp;gt;https://getready.govt.nz/emergency/earthquakes&amp;lt;/ref&amp;gt;&lt;br /&gt;

&lt;div&gt;&amp;lt;span style=&amp;quot;font-size:130%;font-family:serif&amp;quot;&amp;gt;The Collapsible Project&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The goal of this project is to gather strategies, skills, disciplines, technologies, ideas, designs and critical thought in an effort to help prepare communities big and small for a time of great upheaval, an era of collapses (plural). It is not a submission to &#039;The Collapse&#039; and nor does it seek to romanticise an end times. Within this frame, individual-centered survivalist and prepper cultures are not encouraged, while we identify that both hold much that may be of use to communities facing tough times.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;In contributing to this wiki you:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
*    identify that we face not some future Collapse, but are already in the midst of multiple converging collapses.&lt;br /&gt;
*    recognise that the climate and extinction crises are due to the stresses our growth-addicted civilisation has placed on the Planet, and with that comes consequences for all alive.&lt;br /&gt;
*    understand that species extinction and a changed climate can not be undone, that we are already locked in for decades of consequences regardless of any mitigating steps made today.&lt;br /&gt;
*    understand that many communities are already enduring significant and sudden changes, and that we have much to learn from them.&lt;br /&gt;
*    believe that openly discussing and addressing the challenges we face is not &#039;negative&#039;, nor pessimistic, but essential to overcoming them.&lt;br /&gt;
*    understand that environmental defense and biome conservation today is crucial for our survival tomorrow.&lt;br /&gt;
*    recognise that socio-political and geo-political tensions are both expressions and major drivers within collapse.&lt;br /&gt;
*    recognise that true resilience means togetherness, and that strong communities are built atop a commitment to inclusivity.&lt;br /&gt;
*    honestly think tardigrades are amazing, not only because they are collapsible.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;&#039;&#039;If you want to go fast, go alone. If you want to go far, go together&lt;br /&gt;
&#039;&#039;&#039;&#039;&#039;            &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;- Probably an African proverb&#039;&#039;&lt;br /&gt;

== About this wiki ==&lt;br /&gt;
&lt;br /&gt;
This wiki exists as a collaborative notepad to collect and organise content for the Collapsible project, with a social media tentacle at the Mastodon instance at [https://collapsible.systems Collapsible.Systems]. It was launched on September 1, 2023. We are aiming to create a &#039;real&#039; wiki, with useful articles and conforming to a common editorial style, a &#039;collapsipedia&#039;. For this a domain has already been registered. &lt;br /&gt;
&lt;br /&gt;
The wiki will be built primarily as an online archive, but with offline networking applications in mind. A core outcome target is for the entire wiki to be served wirelessly (WLAN, single cell base station, packet radio) and over Ethernet from small low powered computers. PDF, e-pub and print-on-demand outcomes will also be explored. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Unlike other wikis that solely focus on sustainability or lone prepping, the Collapsible Wiki widens its scope to a holistic view on resilience, from organisational systems to disaster preparedness, radio communications, &#039;permacomputing&#039;, medicine and climate resilient cropping.&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
This work will be done in English, translated into other languages where translators are available.&lt;br /&gt;
&lt;br /&gt;
For the time being the priority is to gather all the external resources we can into one place (this wiki), using our Mastodon community as a sort of knowledge harvester.&lt;br /&gt;

=== Scope ===&lt;br /&gt;
&lt;br /&gt;
Rather than write detailed HOWTOs or get into extreme detail, the wiki should aim to provide &#039;&#039;helpful overviews&#039;&#039; to raise literacy, seed confidence, and get folk started on their preparation projects.&lt;br /&gt;
&lt;br /&gt;
The initial goal however is just to collect as many helpful resources here as possible for each section. That process can be really rough for now. If you just have links and don&#039;t know where to put them, just give them a quick title/descrip and drop them in the [[linkdump|Link Dump]]. That said, enthusiastic editors should feel free to flesh out articles and/or write up detailed notes, creating pages as needed. &lt;br /&gt;
&lt;br /&gt;
Before creating a new page, and for each contribution, editors are encouraged to check their entries for &#039;&#039;&#039;&#039;&#039;Utility&#039;&#039;&#039;&#039;&#039; (is the information useful, can it be applied?), &#039;&#039;&#039;&#039;&#039;Relevance&#039;&#039;&#039;&#039;&#039; (does it speak to the Collapsible frame?), &#039;&#039;&#039;&#039;&#039;Inclusivity&#039;&#039;&#039;&#039;&#039; (does it assume a particular audience, leaving out others?), &#039;&#039;&#039;&#039;&#039;Uniqueness&#039;&#039;&#039;&#039;&#039; (can it be found elsewhere in the wiki?), &#039;&#039;&#039;&#039;&#039;Accessibility&#039;&#039;&#039;&#039;&#039; (can it be understood without  prior knowledge, or with knowledge provided in situ?) and &#039;&#039;&#039;&#039;&#039;Region&#039;&#039;&#039;&#039;&#039; (does it assume a particular region to have relevance?).&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;&amp;lt;span style=&amp;quot;font-size:130%;font-family:serif&amp;quot;&amp;gt;The Collapsible Project&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The goal of this project is to gather strategies, skills, disciplines, technologies, ideas, designs and critical thought in an effort to help prepare communities big and small for a time of great upheaval, an era of collapses (plural). It is not a submission to &#039;The Collapse&#039; and nor does it seek to romanticise an end times. Within this frame, individual-centered survivalist and prepper cultures are not encouraged, while we identify that both hold much that may be of use to communities facing tough times.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;In contributing to this wiki you:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
*    identify that we face not some future Collapse, but are already in the midst of multiple converging collapses.&lt;br /&gt;
*    recognise that the climate and extinction crises are due to the stresses our growth-addicted civilisation has placed on the Planet, and with that comes consequences for all alive.&lt;br /&gt;
*    understand that species extinction and a changed climate can not be undone, that we are already locked in for decades of consequences regardless of any mitigating steps made today.&lt;br /&gt;
*    understand that many communities are already enduring significant and sudden changes, and that we have much to learn from them.&lt;br /&gt;
*    believe that openly discussing and addressing the challenges we face is not &#039;negative&#039;, nor pessimistic, but essential to overcoming them.&lt;br /&gt;
*    understand that environmental defense and biome conservation today is crucial for our survival tomorrow.&lt;br /&gt;
*    recognise that socio-political and geo-political tensions are major drivers within collapse.&lt;br /&gt;
*    recognise that true resilience means togetherness, and that strong communities are built atop a commitment to inclusivity.&lt;br /&gt;
*    honestly think tardigrades are amazing, not only because they are collapsible.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;&#039;&#039;If you want to go fast, go alone. If you want to go far, go together&lt;br /&gt;
&#039;&#039;&#039;&#039;&#039;            &lt;br /&gt;
&lt;br /&gt;

== About this wiki ==&lt;br /&gt;
&lt;br /&gt;
This wiki exists as a collaborative notepad to collect and organise content for the Collapsible project, with a social media tentacle at the Mastodon instance at [https://collapsible.systems Collapsible.Systems]. It was launched on September 1, 2023. We are aiming to create a &#039;real&#039; wiki, with useful articles and conforming to a common editorial style, a &#039;collapsipedia&#039;. For this a domain has already been registered. &lt;br /&gt;
&lt;br /&gt;
The wiki will be built primarily as an online archive, but with offline networking applications in mind. A core outcome target is for the entire wiki to be served wirelessly (WLAN, single cell base station, packet radio) and over Ethernet from small low powered computers. PDF, e-pub and print-on-demand outcomes will also be explored. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Unlike other wikis that solely focus on sustainability or lone prepping, the Collapsible Wiki widens its scope to a holistic view on resilience, from organisational systems to disaster preparedness, radio communications, &#039;permacomputing&#039;, medicine and climate resilient cropping.&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
This work will be done in English, translated into other languages where translators are available.&lt;br /&gt;
&lt;br /&gt;
For the time being the priority is to gather all the external resources we can into one place (this wiki), using our Mastodon community as a sort of knowledge harvester.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;== Introduction ==&lt;br /&gt;
&lt;br /&gt;
Offline and off-grid networking broadly refers to the practice of sharing information between devices without use of the global Internet. The advantage of this in a disaster scenario is to provide a fallback for access to critical information and communication services in cases where reaching the Internet is not possible. This can be done with a device acting as a WiFi access point and router, LoRaWAN devices sharing information over long distances using the LoRa radio specification, or with a digital radio service known as &#039;&#039;packet radio&#039;&#039;. Each of these will be covered here.&lt;br /&gt;
&lt;br /&gt;
== WiFi ==&lt;br /&gt;
&lt;br /&gt;
WiFi (or Wi-Fi) refers to certain wireless protocols from the 802.11 collection of standards. WiFi is predominantly used for low power, short range networking, and centers around 2 popular bands, 2.4GHz and the faster 5GHz&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/Wi-Fi&amp;lt;/ref&amp;gt;. In 2019, it was found more than 3.05 billion Wi-Fi-enabled devices are shipped globally each year&amp;lt;ref&amp;gt;https://www.researchandmarkets.com/reports/5135535/global-wi-fi-enabled-devices-shipment-forecast&amp;lt;/ref&amp;gt;. Each of these devices can connect to any wireless access point which is open, or for which they are authenticated. This presents a significant opportunity for the distribution of critical information where Internet access is otherwise not available. &lt;br /&gt;
&lt;br /&gt;
=== Offline WiFi access points ===&lt;br /&gt;
&lt;br /&gt;
Due to our habitual relationship with WiFi and connecting to the public Internet, we can often overlook WiFi&#039;s applications in &#039;offline&#039; contexts. A WiFi access point (AP) does not need the public Internet to provide access to content, if the content is locally accessible to the AP. In such applications, either the WiFi router itself holds the data (perhaps on a USB stick), or the data is served from another device connected directly to the AP. &lt;br /&gt;
&lt;br /&gt;
This is an interesting direction for those more technically minded wishing to provide basic services, like a source of information (WiKi or message board), when the Internet is down. Due to the short range of WiFi, such offline access point servers are best setup at a common communal area, like a community center or disaster meeting point.&lt;br /&gt;
&lt;br /&gt;
==== OpenWrt ====&lt;br /&gt;
&lt;br /&gt;
Some commercial routers provide ability for file sharing across their network using the factory firmware installed on the device. However in the majority of applications, an &#039;&#039;after market&#039;&#039; firmware is used, like OpenWrt&amp;lt;ref&amp;gt;https://openwrt.org&amp;lt;/ref&amp;gt;. Suitable for those more technically inclined, OpenWrt is an open source project dedicated to writing and testing firmware that can be &#039;flashed&#039; onto scavenged or bought WiFi routers, providing them with new functionality and customisation options. At the time of writing, 2043 wireless routers are supported by OpenWrt to some degree&amp;lt;ref&amp;gt;https://openwrt.org/toh/start&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Many projects have been made exploring the practical application of offline networking in a wireless context using OpenWrt. &lt;br /&gt;
&lt;br /&gt;
==== Turning a computer into an offline wireless server ====&lt;br /&gt;
&lt;br /&gt;
Laptops and small form-factor computers can be repurposed as WiFi access points, that either route through to another network (like the Internet) or remain hermetic. Any GNU/Linux laptop or device (like Raspberry Pi) with a wireless network adapter can be repurposed as a wireless access point serving information and files from a locally hosted website. A popular webserver for use in such contexts is &#039;&#039;lighttpd&#039;&#039;. A popular daemon/service providing access point functionality is &#039;&#039;hostapd&#039;&#039;, often coupled with &#039;&#039;dnsmasq&#039;&#039; to provide automatic network configuration of clients using the DHCP protocol alongside domain name resolution&amp;lt;ref&amp;gt;https://w1.fi/hostapd/&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;https://dnsmasq.org/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== WiFi mesh networks ==&lt;br /&gt;
[[File:Berliner freifunk netz 03-01-2007.jpg|thumb|Image showing connections between nodes of the Freifunk network in Berlin in 2007.]]&lt;br /&gt;
&lt;br /&gt;
Mesh networks are computer networks that have in-built node redundancy, meaning that no central node is critical to the distribution of information across the network. Routing algorithms ensure that if a node is unavailable along the route, another optimised route is chosen. Mesh networks are in wide use throughout military and disaster response applications, but can also be deployed and managed by civilians with low cost equipment.&lt;br /&gt;
&lt;br /&gt;
A low power mesh network run by a community atop dumpster-dived/recycled or bought wireless routers could provide a valuable means of distributing mission-critical information where [[Cellular communications|cellular infrastructure]] or the public Internet is otherwise unavailable. Due to the short-throw of WiFi, for this to be useful in a disaster situation, a built-up urban area would require many such WiFi mesh nodes for there to be failure-tolerance and routing-redundancy. Further, most WiFi routers are wall-powered, and so in the event of a blackout a typical wireless router repurposed as a WiFi mesh node will be down.&lt;br /&gt;
&lt;br /&gt;
=== Freifunk ===&lt;br /&gt;
&lt;br /&gt;
Among the most well known and successful WiFi mesh networks in the world is Freifunk. Established in 2003 in Germany, one of the primary goals of the project is to build a large-scale free wireless Wi-Fi network that is decentralized, free of discrimination (net neutrality), owned by those who run it, and to support local communication independent of the public Internet&amp;lt;ref&amp;gt;https://freifunk.net/en/&amp;lt;/ref&amp;gt;. Comprising over 41,000 wireless access points run by civilians, the Freifunk firmware is based atop OpenWrt and runs the &#039;&#039;batman-adv&#039;&#039; (B.A.T.M.A.N) mesh networking protocol, which is actively developed by Freifunk activists&amp;lt;ref&amp;gt;https://openwrt.org/docs/guide-user/network/wifi/mesh/batman&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
The Freifunk firmware can be freely downloaded and modified to be deployed anywhere&amp;lt;ref&amp;gt;https://wiki.freifunk.net/Freifunk-Firmware&amp;lt;/ref&amp;gt;(DE).&lt;br /&gt;
&lt;br /&gt;
=== Red Hook WiFi ===&lt;br /&gt;
&lt;br /&gt;
Red Hook Wifi was established in Red Hook, Brooklyn, New York City in 2011&amp;lt;ref&amp;gt;https://redhookwifi.org/&amp;lt;/ref&amp;gt;. It was created by the Red Hook Initiative to provide access to broadband for the regions many residents. A survey found that many people in the area accessed the internet primarily through mobile phones and that over 30% of the population did not have broadband access at home. &amp;lt;ref&amp;gt;https://urbanomnibus.net/2013/09/red-hook-wifi/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Red Hook serves as an excellent example of community-run infrastructure serving a critically important role in an environmental emergency. In 2012, when Hurricane Sandy hit the region, Internet and cellular communications systems were down&amp;lt;ref&amp;gt;http://nymag.com/intelligencer/2017/10/what-happens-to-the-internet-after-a-disaster.html&amp;lt;/ref&amp;gt;. During this crisis the Red Hook mesh network not only remained active, but the Red Hook headquarters became a hub for volunteer coordination and food distribution, and residents came to the Red Hook Initiative&#039;s office to charge their devices and connect to the internet&amp;lt;ref&amp;gt;https://www.nycedc.com/blog-entry/rising-challenge-red-hook-initiative&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;https://www.forbes.com/sites/deannazandt/2012/11/10/what-sandy-has-taught-us-about-technology-relief-and-resilience/#4db1984f5947&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Soon after Hurricane Sandy hit, the Federal Emergency Management Agency of the United States connected itself to the Red Hook Network, providing a satellite uplink, connecting itself, the Red Cross and residents such that they could find out about food banks, shelters and emergency information&amp;lt;ref&amp;gt;https://www.smh.com.au/technology/meshnets-serve-communities-when-internet-fails-20140515-zrdqe.html&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== SubNodes ===&lt;br /&gt;
&lt;br /&gt;
SubNodes, by Berlin-based artist Sarah Grant, employs popular &#039;&#039;Raspberry Pi&#039;&#039; minicomputers as wireless access points, serving a website and chat application &amp;lt;ref&amp;gt;http://subnodes.org/&amp;lt;/ref&amp;gt;. Smartphones, for instance, can be used to connect to the access point, from which is served a website, alongside simple chat application. The project provides complete instructions requiring minimal prior knowledge for deploying a &#039;SubNode&#039;. Such &#039;SubNodes&#039; could be employed inside weatherproof plastic cases, like tupperware or a plastic lunchbox, powered off solar power bank or voltage-converted car battery, and used to provide valuable information without need for the Internet. SubNodes can also be used in a mesh networking capacity, connecting to other compatible nodes.&lt;br /&gt;
&lt;br /&gt;
=== Other mesh networks by region === &lt;br /&gt;
&lt;br /&gt;
Wikipedia hosts a page dedicated to listing mesh networks by region&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/List_of_wireless_community_networks_by_region&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== LoRa/LoRaWAN ==&lt;br /&gt;
[[File:Adafruit-lora-rpi.jpg|thumb|120px|right|An Adafruit LoRa shield atop a Rasberry Pi Model 4, with 900MHz omnidirectional antenna.]]&lt;br /&gt;
&lt;br /&gt;
[[File:Meshtastic-Station-G2 .jpg|thumb|240px|left|A Meshtastic Station G2 LoRa mesh networking device with attached omnidirectional 900MHz antenna]]&lt;br /&gt;
&lt;br /&gt;
LoRa (from &#039;long range&#039;) is a communication protocol that allows for the transmitting and receiving of data in license-free portions of the radio spectrum. Together with LoRaWAN, it represents is an interesting low cost, low power, wide area networking platform, that can be used to create robust mesh networks. Mobility, end-to-end security and location are all features implemented by the LoRa architecture. While the data rate of LoRa is significantly smaller than that of [[Cellular communications|cellular]] or wireless networks, operating from 0.3 kbit/s to 50 kbit/s per channel, it is sufficient for a diverse applications such as the sending of location information, messages and chat, status updates, sensor output, etc. The longest 2-way conversation between LoRa devices using less than 1 Watt of power is 206 km (128 miles)&amp;lt;ref&amp;gt;https://hackaday.com/2023/06/26/meshtastic-for-the-greater-good/&amp;lt;/ref&amp;gt;. Several kilometers of mesh contact are quite typical for even low-power off-the-shelf LoRa devices, making LoRa an especially interesting solution for emergency communications, both in urban and rural contexts.&lt;br /&gt;
&lt;br /&gt;
One practical mobile application of LoRa is MsgLab, where it is employed as a small handset with keyboard and case such that it can be used for texting in off-grid contexts&amp;lt;ref&amp;gt;https://www.msglab.co/&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
=== Meshtastic ===&lt;br /&gt;
&lt;br /&gt;
The Meshtastic project is a unique LoRa implementation with a very large global community of user-operated mesh nodes. This consumer-facing solution provides a modular platform with broad selection of hardware options that is easy to get up and running for those less technical. Various interfaces to the hardware (including apps and web-based) are provided. Setup and configuration is done on a smartphone via an app over bluetooth, and requires little-to-no prior knowledge. A large community exists to support those in need of help.&lt;br /&gt;
&lt;br /&gt;
Meshtastic leverages the fact that people are often already carrying smartphones, allowing messages to be sent from a paired smartphone over bluetooth to the device, the messages of which are in turn either broadcast to a public channel on the mesh, or to a user-configured encrypted channel of devices on the mesh (for instance to devices of friends and family in the region).&amp;lt;ref&amp;gt;https://meshtastic.org/&amp;lt;/ref&amp;gt;. In this sense, Meshtastic can be considered to be a little like a very long range &#039;pager&#039; using a smartphone as the messaging interface. &lt;br /&gt;
&lt;br /&gt;
Low power, some portable Meshtastic devices can run for days on built-in batteries, and come in a small form-factor. The SenseCAP T1000 model, for instance, is little larger than a credit card. &lt;br /&gt;

&lt;div&gt;== Introduction ==&lt;br /&gt;
&lt;br /&gt;
Offline and off-grid networking broadly refers to the practice of sharing information between devices without use of the global Internet. The advantage of this in a disaster scenario is to provide a fallback for access to critical information and communication services in cases where reaching the Internet is not possible. This can be done with a device acting as a WiFi access point and router, LoRaWAN devices sharing information over long distances using the LoRa radio specification, or with a digital radio service known as &#039;&#039;packet radio&#039;&#039;. Each of these will be covered here.&lt;br /&gt;
&lt;br /&gt;
== WiFi ==&lt;br /&gt;
&lt;br /&gt;
WiFi (or Wi-Fi) refers to certain wireless protocols from the 802.11 collection of standards. WiFi is predominantly used for low power, short range networking, and centers around 2 popular bands, 2.4GHz and the faster 5GHz&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/Wi-Fi&amp;lt;/ref&amp;gt;. In 2019, it was found more than 3.05 billion Wi-Fi-enabled devices are shipped globally each year&amp;lt;ref&amp;gt;https://www.researchandmarkets.com/reports/5135535/global-wi-fi-enabled-devices-shipment-forecast&amp;lt;/ref&amp;gt;. Each of these devices can connect to any wireless access point which is open, or for which they are authenticated. This presents a significant opportunity for the distribution of critical information where Internet access is otherwise not available. &lt;br /&gt;
&lt;br /&gt;
=== Offline WiFi access points ===&lt;br /&gt;
&lt;br /&gt;
Due to our habitual relationship with WiFi and connecting to the public Internet, we can often overlook WiFi&#039;s applications in &#039;offline&#039; contexts. A WiFi access point (AP) does not need the public Internet to provide access to content, if the content is locally accessible to the AP. In such applications, either the WiFi router itself holds the data (perhaps on a USB stick), or the data is served from another device connected directly to the AP. &lt;br /&gt;
&lt;br /&gt;
This is an interesting direction for those more technically minded wishing to provide basic services, like a source of information (WiKi or message board), when the Internet is down. Due to the short range of WiFi, such offline access point servers are best setup at a common communal area, like a community center or disaster meeting point.&lt;br /&gt;
&lt;br /&gt;
==== OpenWrt ====&lt;br /&gt;
&lt;br /&gt;
Some commercial routers provide ability for file sharing across their network using the factory firmware installed on the device. However in the majority of applications, an &#039;&#039;after market&#039;&#039; firmware is used, like OpenWrt&amp;lt;ref&amp;gt;https://openwrt.org&amp;lt;/ref&amp;gt;. Suitable for those more technically inclined, OpenWrt is an open source project dedicated to writing and testing firmware that can be &#039;flashed&#039; onto scavenged or bought WiFi routers, providing them with new functionality and customisation options. At the time of writing, 2043 wireless routers are supported by OpenWrt to some degree&amp;lt;ref&amp;gt;https://openwrt.org/toh/start&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Many projects have been made exploring the practical application of offline networking in a wireless context using OpenWrt. &lt;br /&gt;
&lt;br /&gt;
==== Turning a computer into an offline wireless server ====&lt;br /&gt;
&lt;br /&gt;
Laptops and small form-factor computers can be repurposed as WiFi access points, that either route through to another network (like the Internet) or remain hermetic. Any GNU/Linux laptop or device (like Raspberry Pi) with a wireless network adapter can be repurposed as a wireless access point serving information and files from a locally hosted website. A popular webserver for use in such contexts is &#039;&#039;lighttpd&#039;&#039;. A popular daemon/service providing access point functionality is &#039;&#039;hostapd&#039;&#039;, often coupled with &#039;&#039;dnsmasq&#039;&#039; to provide automatic network configuration of clients using the DHCP protocol alongside domain name resolution&amp;lt;ref&amp;gt;https://w1.fi/hostapd/&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;https://dnsmasq.org/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== WiFi mesh networks ==&lt;br /&gt;
[[File:Berliner freifunk netz 03-01-2007.jpg|thumb|Image showing connections between nodes of the Freifunk network in Berlin in 2007.]]&lt;br /&gt;
&lt;br /&gt;
Mesh networks are computer networks that have in-built node redundancy, meaning that no central node is critical to the distribution of information across the network. Routing algorithms ensure that if a node is unavailable along the route, another optimised route is chosen. Mesh networks are in wide use throughout military and disaster response applications, but can also be deployed and managed by civilians with low cost equipment.&lt;br /&gt;
&lt;br /&gt;
A low power mesh network run by a community atop dumpster-dived/recycled or bought wireless routers could provide a valuable means of distributing mission-critical information where [[Cellular communications|cellular infrastructure]] or the public Internet is otherwise unavailable. Due to the short-throw of WiFi, for this to be useful in a disaster situation, a built-up urban area would require many such WiFi mesh nodes for there to be failure-tolerance and routing-redundancy. Further, most WiFi routers are wall-powered, and so in the event of a blackout a typical wireless router repurposed as a WiFi mesh node will be down.&lt;br /&gt;
&lt;br /&gt;
=== Freifunk ===&lt;br /&gt;
&lt;br /&gt;
Among the most well known and successful WiFi mesh networks in the world is Freifunk. Established in 2003 in Germany, one of the primary goals of the project is to build a large-scale free wireless Wi-Fi network that is decentralized, free of discrimination (net neutrality), owned by those who run it, and to support local communication independent of the public Internet&amp;lt;ref&amp;gt;https://freifunk.net/en/&amp;lt;/ref&amp;gt;. Comprising over 41,000 wireless access points run by civilians, the Freifunk firmware is based atop OpenWrt and runs the &#039;&#039;batman-adv&#039;&#039; (B.A.T.M.A.N) mesh networking protocol, which is actively developed by Freifunk activists&amp;lt;ref&amp;gt;https://openwrt.org/docs/guide-user/network/wifi/mesh/batman&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
The Freifunk firmware can be freely downloaded and modified to be deployed anywhere&amp;lt;ref&amp;gt;https://wiki.freifunk.net/Freifunk-Firmware&amp;lt;/ref&amp;gt;(DE).&lt;br /&gt;
&lt;br /&gt;
=== Red Hook WiFi ===&lt;br /&gt;
&lt;br /&gt;
Red Hook Wifi was established in Red Hook, Brooklyn, New York City in 2011&amp;lt;ref&amp;gt;https://redhookwifi.org/&amp;lt;/ref&amp;gt;. It was created by the Red Hook Initiative to provide access to broadband for the regions many residents. A survey found that many people in the area accessed the internet primarily through mobile phones and that over 30% of the population did not have broadband access at home. &amp;lt;ref&amp;gt;https://urbanomnibus.net/2013/09/red-hook-wifi/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Red Hook serves as an excellent example of community-run infrastructure serving a critically important role in an environmental emergency. In 2012, when Hurricane Sandy hit the region, Internet and cellular communications systems were down&amp;lt;ref&amp;gt;http://nymag.com/intelligencer/2017/10/what-happens-to-the-internet-after-a-disaster.html&amp;lt;/ref&amp;gt;. During this crisis the Red Hook mesh network not only remained active, but the Red Hook headquarters became a hub for volunteer coordination and food distribution, and residents came to the Red Hook Initiative&#039;s office to charge their devices and connect to the internet&amp;lt;ref&amp;gt;https://www.nycedc.com/blog-entry/rising-challenge-red-hook-initiative&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;https://www.forbes.com/sites/deannazandt/2012/11/10/what-sandy-has-taught-us-about-technology-relief-and-resilience/#4db1984f5947&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Soon after Hurricane Sandy hit, the Federal Emergency Management Agency of the United States connected itself to the Red Hook Network, providing a satellite uplink, connecting itself, the Red Cross and residents such that they could find out about food banks, shelters and emergency information&amp;lt;ref&amp;gt;https://www.smh.com.au/technology/meshnets-serve-communities-when-internet-fails-20140515-zrdqe.html&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== SubNodes ===&lt;br /&gt;
&lt;br /&gt;
SubNodes, by Berlin-based artist Sarah Grant, employs popular &#039;&#039;Raspberry Pi&#039;&#039; minicomputers as wireless access points, serving a website and chat application &amp;lt;ref&amp;gt;http://subnodes.org/&amp;lt;/ref&amp;gt;. Smartphones, for instance, can be used to connect to the access point, from which is served a website, alongside simple chat application. The project provides complete instructions requiring minimal prior knowledge for deploying a &#039;SubNode&#039;. Such &#039;SubNodes&#039; could be employed inside weatherproof plastic cases, like tupperware or a plastic lunchbox, powered off solar power bank or voltage-converted car battery, and used to provide valuable information without need for the Internet. SubNodes can also be used in a mesh networking capacity, connecting to other compatible nodes.&lt;br /&gt;
&lt;br /&gt;
=== Other mesh networks by region === &lt;br /&gt;
&lt;br /&gt;
Wikipedia hosts a page dedicated to listing mesh networks by region&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/List_of_wireless_community_networks_by_region&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== LoRa/LoRaWAN ==&lt;br /&gt;
[[File:Adafruit-lora-rpi.jpg|thumb|120px|right|An Adafruit LoRa shield atop a Rasberry Pi Model 4, with 900MHz omnidirectional antenna.]]&lt;br /&gt;
&lt;br /&gt;
[[File:Meshtastic-Station-G2 .jpg|thumb|240px|left|A Meshtastic Station G2 LoRa mesh networking device with attached omnidirectional 900MHz antenna]]&lt;br /&gt;
&lt;br /&gt;
LoRa (from &#039;long range&#039;) is a communication protocol that allows for the transmitting and receiving of data in license-free portions of the radio spectrum. Together with LoRaWAN, it represents is an interesting low cost, low power, wide area networking platform, that can be used to create robust mesh networks. Mobility, end-to-end security and location are all features implemented by the LoRa architecture. While the data rate of LoRa is significantly smaller than that of [[Cellular communications|cellular]] or wireless networks, operating from 0.3 kbit/s to 50 kbit/s per channel, it is sufficient for a diverse applications such as the sending of location information, messages and chat, status updates, sensor output, etc. The longest 2-way conversation between LoRa devices using less than 1 Watt of power is 206 km (128 miles)&amp;lt;ref&amp;gt;https://hackaday.com/2023/06/26/meshtastic-for-the-greater-good/&amp;lt;/ref&amp;gt;. Several kilometers of mesh contact are quite typical for even low-power off-the-shelf LoRa devices, making LoRa an especially interesting solution for emergency communications, both in urban and rural contexts.&lt;br /&gt;
&lt;br /&gt;
One practical mobile application of LoRa is MsgLab, where it is employed as a small handset with keyboard and case such that it can be used for texting in off-grid contexts&amp;lt;ref&amp;gt;https://www.msglab.co/&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
=== Meshtastic ===&lt;br /&gt;
&lt;br /&gt;
The Meshtastic project is a unique LoRa implementation with a very large global community of user-operated mesh nodes. This consumer-facing solution provides a modular platform whereby LoRa hardware, battery, and case and antenna are purchased, a web-based flasher is used to deploy the software onto the hardware. Various interfaces to the hardware (including apps and web-based) are provided. Meshtastic can be a good solution for resilient communications, especially for those less technical. Setup and configuration is done on a smartphone via an app, and requires little-to-no prior knowledge. A large community exists to support those less technical. &lt;br /&gt;
&lt;br /&gt;
Meshtastic leverages the fact that people are often already carrying smartphones, allowing messages to be sent from a paired smartphone over bluetooth to the device, the messages of which are in turn either broadcast to a public channel on the mesh, or to a user-configured encrypted channel of devices on the mesh (for instance to devices of friends and family in the region).&amp;lt;ref&amp;gt;https://meshtastic.org/&amp;lt;/ref&amp;gt;. In this sense, Meshtastic can be considered to be a little like a long range &#039;pager&#039; using a smartphone as the messaging interface. &lt;br /&gt;
&lt;br /&gt;
Low power, some portable Meshtastic devices can run for days on built-in batteries, and come in a small form-factor. The SenseCAP T1000 model, for instance, is little larger than a credit card. &lt;br /&gt;

SubNodes can also be used in a mesh networking capacity, connecting to other compatible nodes.&lt;br /&gt;

&lt;br /&gt;
LoRa (from &#039;long range&#039;) is a communication protocol that allows for the transmitting and receiving of data in license-free portions of the radio spectrum. Together with LoRaWAN, it represents is an interesting low cost, low power, wide area networking platform, that can be used to create robust mesh networks. Mobility, end-to-end security and location are all features implemented by the LoRa architecture. While the data rate of LoRa is significantly smaller than that of [[Cellular communications|cellular]] or wireless networks, operating from 0.3 kbit/s to 50 kbit/s per channel, it is sufficient for a diverse applications such as the sending of location information, messages and chat, status updates, sensor output, etc. The longest 2-way conversation between LoRa devices using less than 1 Watt of power is 206 km (128 miles)&amp;lt;ref&amp;gt;https://hackaday.com/2023/06/26/meshtastic-for-the-greater-good/&amp;lt;/ref&amp;gt;. Several kilometers of mesh contact are quite typical for even low-power off-the-shelf LoRa devices, making LoRa an especially interesting solution for emergency communications, both in urban and rural contexts.&lt;br /&gt;
&lt;br /&gt;
One practical mobile application of LoRa is MsgLab, where it is employed as a small handset with keyboard and case such that it can be used for texting in off-grid contexts&amp;lt;ref&amp;gt;https://www.msglab.co/&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
=== Meshtastic ===&lt;br /&gt;
&lt;br /&gt;
The Meshtastic project is a unique LoRa implementation with a very large global community of user-operated mesh nodes. This consumer-facing solution provides a modular platform whereby LoRa hardware, battery, and case and antenna are purchased, a web-based flasher is used to deploy the software onto the hardware. Various interfaces to the hardware (including apps and web-based) are provided. Meshtastic can be a good solution for resilient communications, especially for those less technical. Setup and configuration is done on a smartphone via an app, and requires little-to-no prior knowledge. A large community exists to support those less technical. &lt;br /&gt;
&lt;br /&gt;
Meshtastic leverages the fact that people are often already carrying smartphones, allowing messages to be sent from a paired smartphone over bluetooth to the device, the messages of which are in turn either broadcast to a public channel on the mesh, or to a user-configured encrypted channel of devices on the mesh (for instance to devices of friends and family in the region).&amp;lt;ref&amp;gt;https://meshtastic.org/&amp;lt;/ref&amp;gt;. In this sense, Meshtastic can be considered to be a little like a long range &#039;pager&#039; using a smartphone as the messaging interface. &lt;br /&gt;
&lt;br /&gt;
Low power, some portable Meshtastic devices can run for days on built-in batteries, and come in a small form-factor. The SenseCAP T1000 model, for instance, is little larger than a credit card. &lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;== Introduction ==&lt;br /&gt;
&lt;br /&gt;
Offline and off-grid networking broadly refers to the practice of sharing information between devices without use of the global Internet. The advantage of this in a disaster scenario is to provide a fallback for access to critical information and communication services in cases where reaching the Internet is not possible. This can be done with a device acting as a WiFi access point and router, LoRaWAN devices sharing information over long distances using the LoRa radio specification, or with a digital radio service known as &#039;&#039;packet radio&#039;&#039;. Each of these will be covered here.&lt;br /&gt;
&lt;br /&gt;
== WiFi ==&lt;br /&gt;
&lt;br /&gt;
WiFi (or Wi-Fi) refers to certain wireless protocols from the 802.11 collection of standards. WiFi is predominantly used for low power, short range networking, and centers around 2 popular bands, 2.4GHz and the faster 5GHz&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/Wi-Fi&amp;lt;/ref&amp;gt;. In 2019, it was found more than 3.05 billion Wi-Fi-enabled devices are shipped globally each year&amp;lt;ref&amp;gt;https://www.researchandmarkets.com/reports/5135535/global-wi-fi-enabled-devices-shipment-forecast&amp;lt;/ref&amp;gt;. Each of these devices can connect to any wireless access point which is open, or for which they are authenticated. This presents a significant opportunity for the distribution of critical information where Internet access is otherwise not available.&lt;br /&gt;
&lt;br /&gt;
=== Offline WiFi access points ===&lt;br /&gt;
&lt;br /&gt;
Due to our habitual relationship with WiFi and connecting to the public Internet, we can often overlook WiFi&#039;s applications in &#039;offline&#039; contexts. A a WiFi access point (AP) does not need the public Internet to provide access to content, if the content is locally accessible to the AP. In such applications, either the WiFi router itself holds the data (perhaps on a USB stick), or the data is served from another device connected directly to the AP. &lt;br /&gt;
&lt;br /&gt;
==== OpenWrt ====&lt;br /&gt;
&lt;br /&gt;
Some commercial routers provide ability for file sharing across their network using the factory firmware installed on the device. However in the majority of applications, an &#039;&#039;after market&#039;&#039; firmware is used, like OpenWrt&amp;lt;ref&amp;gt;https://openwrt.org&amp;lt;/ref&amp;gt;. OpenWrt is an open source project and community dedicated to writing and testing firmware that can be &#039;flashed&#039; onto scavenged or bought WiFi routers, providing them with new functionality and customisation options. At the time of writing, 2043 wireless access points are supported by OpenWrt to some degree&amp;lt;ref&amp;gt;https://openwrt.org/toh/start&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Many projects have been done exploring the practical application of offline networking in a wireless context using OpenWrt. However, many small form-factor computers can be repurposed as WiFi access points, that either route through to another network (like the Internet) or remain hermetic. &lt;br /&gt;
&lt;br /&gt;
For those more technically inclined, any GNU/Linux laptop or device with a wireless network adapter can be repurposed as a wireless access point serving information and files from a locally hosted website. A popular webserver for use in such contexts is &#039;&#039;lighttpd&#039;&#039;. A popular daemon/service providing access point functionality is &#039;&#039;hostapd&#039;&#039;, often coupled with &#039;&#039;dnsmasq&#039;&#039; to provide automatic network configuration of clients using the DHCP protocol alongside domain name resolution&amp;lt;ref&amp;gt;https://w1.fi/hostapd/&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;https://dnsmasq.org/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== WiFi mesh networks ==&lt;br /&gt;
[[File:Berliner freifunk netz 03-01-2007.jpg|thumb|Image showing connections between nodes of the Freifunk network in Berlin in 2007.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Mesh networks are computer networks that have in-built node redundancy, meaning that no central node is critical to the distribution of information across the network. Routing algorithms ensure that if a node is unavailable along the route, another optimised route is chosen. Mesh networks are in wide use throughout military and disaster response applications, but can also be deployed and managed by civilians with low cost equipment.&lt;br /&gt;
&lt;br /&gt;
A low power mesh network run by a community atop dumpster-dived/recycled or bought wireless routers could provide a valuable means of distributing mission-critical information where [[Cellular communications|cellular infrastructure]] or the public Internet is otherwise unavailable.&lt;br /&gt;
&lt;br /&gt;
=== Freifunk ===&lt;br /&gt;
&lt;br /&gt;
Among the most well known and successful WiFi mesh networks in the world is Freifunk. Established in 2003 in Germany, one of the primary goals of the project is to build a large-scale free wireless Wi-Fi network that is decentralized, free of discrimination (net neutrality), owned by those who run it, and to support local communication independent of the public Internet&amp;lt;ref&amp;gt;https://freifunk.net/en/&amp;lt;/ref&amp;gt;. Comprising over 41,000 wireless access points run by civilians, the Freifunk firmware is based atop OpenWrt and runs the &#039;&#039;batman-adv&#039;&#039; (B.A.T.M.A.N) mesh networking protocol, which is actively developed by Freifunk activists&amp;lt;ref&amp;gt;https://openwrt.org/docs/guide-user/network/wifi/mesh/batman&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
The Freifunk firmware can be freely downloaded and modified to be deployed anywhere&amp;lt;ref&amp;gt;https://wiki.freifunk.net/Freifunk-Firmware&amp;lt;/ref&amp;gt;(DE).&lt;br /&gt;
&lt;br /&gt;
=== Red Hook WiFi ===&lt;br /&gt;
&lt;br /&gt;
Red Hook Wifi was established in Red Hook, Brooklyn, New York City in 2011&amp;lt;ref&amp;gt;https://redhookwifi.org/&amp;lt;/ref&amp;gt;. It was created by the Red Hook Initiative to provide access to broadband for the regions many residents. A survey found that many people in the area accessed the internet primarily through mobile phones and that over 30% of the population did not have broadband access at home. &amp;lt;ref&amp;gt;https://urbanomnibus.net/2013/09/red-hook-wifi/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Red Hook serves as an excellent example of community-run infrastructure serving a critically important role in an environmental emergency. In 2012, when Hurricane Sandy hit the region, Internet and cellular communications systems were down&amp;lt;ref&amp;gt;http://nymag.com/intelligencer/2017/10/what-happens-to-the-internet-after-a-disaster.html&amp;lt;/ref&amp;gt;. During this crisis the Red Hook mesh network not only remained active, but the Red Hook headquarters became a hub for volunteer coordination and food distribution, and residents came to the Red Hook Initiative&#039;s office to charge their devices and connect to the internet&amp;lt;ref&amp;gt;https://www.nycedc.com/blog-entry/rising-challenge-red-hook-initiative&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;https://www.forbes.com/sites/deannazandt/2012/11/10/what-sandy-has-taught-us-about-technology-relief-and-resilience/#4db1984f5947&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Soon after Hurricane Sandy hit, the Federal Emergency Management Agency of the United States connected itself to the Red Hook Network, providing a satellite uplink, connecting itself, the Red Cross and residents such that they could find out about food banks, shelters and emergency information&amp;lt;ref&amp;gt;https://www.smh.com.au/technology/meshnets-serve-communities-when-internet-fails-20140515-zrdqe.html&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== SubNodes ===&lt;br /&gt;
&lt;br /&gt;
SubNodes, by Berlin-based artist Sarah Grant, employs popular &#039;&#039;Raspberry Pi&#039;&#039; minicomputers as wireless access points, serving a website and chat application &amp;lt;ref&amp;gt;http://subnodes.org/&amp;lt;/ref&amp;gt;. Smartphones, for instance, can be used to connect to the access point, from which is served a website, alongside simple chat application. The project provides complete instructions requiring minimal prior knowledge for deploying a &#039;SubNode&#039;. Such &#039;SubNodes&#039; could be employed inside weatherproof plastic cases, like tupperware or a plastic lunchbox, powered off solar power bank or voltage-converted car battery, and used to provide valuable information without need for the Internet. SubNodes can also be used in a mesh networking capacity, connecting to other compatible nodes.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;== Introduction ==&lt;br /&gt;
&lt;br /&gt;
This page introduces radio as a practical and reliable communications infrastructure for use in a situations and events where Internet access and mobile communications are not available. &lt;br /&gt;
&lt;br /&gt;
The Internet and mobile networking are complex infrastructures dependent on a stack of technology for their function, from internet exchanges to routing and switching hardware, submarine cables, base stations and their antennae and a stable power grid. This complexity introduces multiple points of vulnerability. For instance, a flood could damage a power station, causing a black out that results in no Internet access at home nor mobile data, texts or calls via the cellular network.&lt;br /&gt;
&lt;br /&gt;
It is here that radio offers a valuable fallback technology for not only receiving critical status updates and information from local authorities and other communities, but also can allow for transmissions from your own community or group that can help you reach others and get needed assistance.&lt;br /&gt;
&lt;br /&gt;
== AM/FM radio reception ==&lt;br /&gt;
&lt;br /&gt;
In an emergency where critical infrastructure is experiencing outage, local information will almost always be broadcast over AM (also sometimes referred to as Medium Wave or MW) and/or FM. It is for this reason, at the least, a simple AM/FM radio with charged batteries and spares should be acquired and stored in an accessible place. They can usually be bought very cheaply. [[File:Am-fm-radio.jpg|thumb|left|A photo of 2 AM/FM radios, each with extendable antenna and headphone jack.]]&lt;br /&gt;
It is good to buy am AM/FM radio with a mini-jack socket and extendable antenna. The mini-jack socket allows for plugging in headphones which can be useful when reception quality is poor. The extendable antenna can greatly aid in finding and receiving a broadcast.&lt;br /&gt;
&lt;br /&gt;
Small radios such as these can be put into a backpack or &#039;go bag&#039;, alongside a spare set of batteries. Rechargeable batteries should be used where possible. It can be a good idea to waterproof your radio by putting it in a quality zip-lock bag, alongside spare batteries held together with a rubber band or tape. Be sure you have tested it and have learned how to use it before you do.&lt;br /&gt;
&lt;br /&gt;
If you are caught out without a radio and have access to a vehicle, it very likely has a built-in AM/FM radio. Note that AM broadcasts travel over vastly longer distances than FM, and so it is important to be aware of this in relation to your geographical context. As always the best reception with radio is line-of-sight. While it is rare we can see the antenna(e) we are receiving a broadcast from, getting to a position of altitude away from RF (radio-frequency) occlusions like buildings and hills can make all the difference in reception.&lt;br /&gt;
&lt;br /&gt;
== Walkie-talkies ==&lt;br /&gt;
&lt;br /&gt;
[[File:Walkie-talkies.jpg|thumb|Two Baofeng BF-9700 Walkie Talkies]]&lt;br /&gt;
&lt;br /&gt;
Unlike AM/FM radios detailed above, walkie-talkies are both broadcast station and receiver, and so known as &#039;two-way&#039; radios. The range of a modern walkie-talkie is anything from a few hundred meters in a city and in dense vegetation, to many kilometers when used on a peak or high rooftop. This communication tool can be especially invaluable when you are in a group and need to split up, staying in contact and relaying information.&lt;br /&gt;
&lt;br /&gt;
Walkie-talkies operate on license-free broadcast frequency ranges in the UHF (Ultra High Frequency) band respective to the region the walkie talkie is purchased within. In the EU the allocation is known PMR446 (Private Mobile Radio, 446 MHz)&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/PMR446&amp;lt;/ref&amp;gt;, whereas in the US it is typically the Family Radio Service (FRS)&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/Family_Radio_Service&amp;lt;/ref&amp;gt; or GMRS&amp;lt;ref&amp;gt;https://www.fcc.gov/wireless/bureau-divisions/mobility-division/general-mobile-radio-service-gmrs&amp;lt;/ref&amp;gt;, and in Australia UHF CB&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/UHF_CB&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Regardless, if you are in a region using 2 or more walkie-talkies operating on unlicensed bands, they will still function, but may overlap with existing local broadcasts. Typically walkie-talkies include a channel selector for selecting a pre-agreed channel to operate on. This selector is either a button or dial. It is important to agree on a channel to use before splitting up your group and using the walkie-talkies. Some walkie talkies also include a radio scanner, allowing the operator to quickly find and tune into a local radio station. Some even include NOAA weather radio receivers.&lt;br /&gt;
&lt;br /&gt;
When selecting a walkie-talkie it is good to ensure it has a high IPX water rating, is durable, has a &#039;squelch&#039; function (allows for &#039;cleaning&#039; up a noisy signal to hear it better), good battery life and has at least 3W of power. Importantly, some walkie-talkies can only be charged in a special charging dock, and so if you choose a walkie-talkie of this sort it is important that it has removable batteries such that you can bring pre-charged batteries with you. If not, it is good to get walkie-talkies that take AA batteries, that you can recharge in a standard battery charger, one of which may include a portable solar charger.&lt;br /&gt;
&lt;br /&gt;
=== 2-way communication guide ===&lt;br /&gt;
&lt;br /&gt;
If you are needing to split up your group, pre-arrange a signals plan such that group parties are not burning through batteries waiting for status updates throughout the period you are apart. That signals plan involves both agreeing on a channel and times or time-windows to be in contact. If the time is known to both parties throughout, specific times or windows of time can be agreed in advance. For instance, on a day long expedition beginning in the morning the expedition party may agree to send status updates at 10:30, noon, 14:30 and between 16:00 and 18:00 as expected range of arrival time. If clocks are not at hand for both parties, sun position will need to be used.&lt;br /&gt;
&lt;br /&gt;
In the event there is a basecamp or base with more than 1 other party working remotely, then all contact should go through basecamp rather than between parties directly. Important information is best written down first for clarity, and to minimise time spent using the handsets so preserving battery life.&lt;br /&gt;
&lt;br /&gt;
Use the &#039;&#039;RSVP&#039;&#039; guide for 2-way communication &amp;lt;ref&amp;gt;SAS Survival Handbook (3rd edition), J. Wiseman, p24&amp;lt;/ref&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
* &#039;&#039;&#039;R&#039;&#039;&#039;hythm - Speak at an even pace&lt;br /&gt;
* &#039;&#039;&#039;S&#039;&#039;&#039;peed - Talk slowly&lt;br /&gt;
* &#039;&#039;&#039;V&#039;&#039;&#039;olume - Speak softly&lt;br /&gt;
* &#039;&#039;&#039;P&#039;&#039;&#039;itch - Speak at a higher pitch than normal and use the phonetic alphabet when spelling out names&lt;br /&gt;
&lt;br /&gt;
While not always easy, try to time your status updates from a position of high altitude. Signals will always be weaker in gullies, valleys, within dense foliage and in between tall buildings.&lt;br /&gt;
&lt;br /&gt;

While far more efficient antenna designs exist, when long range reception is urgently needed, a simple but powerful antenna can be quickly built using shielded or un-shielded copper wire. Such wire can be a single core of common electrical wire used to wire a home, or any copper wire thick enough to withstand the strain of being strung taut between two points. Of all the wires, copper-clad steel wire between 1.6 to 2.0 mm is best however &amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/Random_wire_antenna&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== Random Length Wire Antennae ===&lt;br /&gt;
[[File:Random-wire-antenna.jpeg|thumb|left|Image courtesy George H. Woodward (W1RN), https://arrl.org, taken from https://www.arrl.org/files/file/Technology/tis/info/pdf/0683033.pdf]]&lt;br /&gt;
&lt;br /&gt;
The length of a random wire antenna should correspond to the bands you wish to listen to, and should be at minimum 1/4 of the wavelength of the band at which you wish to receive. &lt;br /&gt;
&lt;br /&gt;
=== Wire antenna for AM reception ===&lt;br /&gt;
&lt;br /&gt;
In a disaster situation with no access to mobile data nor the Internet, and a handheld radio does not provide sufficient reception or is unavailable, AM radio is often a good first option. If you are wanting to listen for local shortwave (AM/MW) broadcasts and have little resources and/or poor reception with a little handheld, even a rough 6 meters length of wire should give you opportunity to listen to many stations within about 500 kHz to 13 MHz. &lt;br /&gt;
&lt;br /&gt;
The most common configuration for random wire antennae is to suspend it between a home (or shelter) and a tree or adjacent structure. A loop can be made in the wire, twisted tight, and paracord or rope used to fasten it to each end. It is important that the wire is electrically insulated from the structures it is tethered to. If just using wire to affix to the structures, ceramic insulators can be added inline at each end, with the feedline to the receiver connected to the suspended antenna section. In the absence of proper ceramic insulators, a ceramic cup with a sturdy handle can be used, with each portion of wire twisted to each end of the handle and the cup horizontal. Alternatively, a solid piece of polyethylene plastic (for instance a dog chew toy, holes put at each end) can be used.&lt;br /&gt;
&lt;br /&gt;
When the wire is short enough, it can alternatively be hung vertically from a roof or tree, and sometimes enjoy better reception as it will have closer polarity (electromagnetic orientation) to that of the broadcasting antenna.&lt;br /&gt;
&lt;br /&gt;
Random wire antennas are ever at risk of electrical storms, and so such an antenna should be electrically grounded. For this exposed metal plumping pipe can be used, or a steel stake driven deep into the ground. If you do not do this, you risk destroying your equipment.&lt;br /&gt;
&lt;br /&gt;
[[File:Homemade_balun.jpeg|thumb|Homemade 1:1 balun using a toroidal core and coaxial cable. This simple RF choke works as a balun by preventing signals passing along the outside of the braid]]&lt;br /&gt;
&lt;br /&gt;
At the receiving end of the random wire antenna, a &#039;&#039;balun&#039;&#039; is ideally used. A balun &#039;balances&#039; an unbalanced line, significantly improving reception quality and mitigating for many Standing Wave Ratio (SWR) challenges, typical of long lines of wire used in a radio context&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/Balun&amp;lt;/ref&amp;gt;. Baluns can be made using a simple toroidal core commonly harvested from electronics at hand, or a professional balun can be purchased suitable for the project.&lt;br /&gt;
&lt;br /&gt;
=== Random wire antennae for hobby and amateur radio bands ===&lt;br /&gt;
&lt;br /&gt;
During emergencies hobby and amateur radio (HAM) bands can be a source of valuable information. Radio operators operating in their homes or &#039;radio shack&#039; may send broadcasts on popular 20M, 40M and 80M bands. These are long-distance bands, sometimes covering hundreds or thousands of kilometers, and so this should be kept in context when seeking information. It is also important to beware the operators of these bands are not necessarily providing authoritative situational status information. For this reason, AM and FM bands should be the preferred choice for reception when mobile data and Internet connectivity is not possible.&lt;br /&gt;
&lt;br /&gt;
If you are wanting to listen to broadcasts on popular amateur radio bands, which have far larger wavelengths (like 40M, 80M), you can try any very long wire you can get your hand on.  Very long wires can allow for tuning across several bands, as the wire will include 1/4, 1/2 and perhaps even full wavelength representations. Using any long wire without a balun will often result in reception suffering from Standing Wave Ratio (SWR) interference due to differences in impedance between the antenna itself and the feedline to the receiver &amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/Standing_wave_ratio#Practical_implications_of_SWR&amp;lt;/ref&amp;gt;. If you are without a balun, you can carefully select a wire for minimum interference. Physicists have studied random wire electromagnetic fields in relation to the SWR phenomenon, and with the aid of computer modeling have determined ideal lengths for minimal interference. An example is J. C. Sprott, a physicist at University of Wisconsin, USA&amp;lt;ref&amp;gt;https://sprott.physics.wisc.edu/technote/randwire.htm&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== Delta Loop Antenna ===&lt;br /&gt;
&lt;br /&gt;
[[File:Delta-antenna-triband.jpg|thumb|320x320px|Example of a multi-band delta loop antenna design, here for the 80m, 40m and 30m bands. This file shared courtesy of Iulian Rosu (YVA3IUL), and as per the attribution in the image]]&lt;br /&gt;
&lt;br /&gt;
The next step up in sophistication and technical challenge from a single straight wire antenna is a &#039;&#039;delta loop antenna&#039;&#039;. It offers improved reception due to having far higher likelihood of matching broadcast polarity. It is quite easy to make, and can be suspended vertically from any high point, for instance affixed to the the peak of a roof, balcony or window and run down the front of the building.&lt;br /&gt;
&lt;br /&gt;
The sides of a delta loop antenna are equal and typically correspond to a 1/2 or 1/4 wavelength. Many designs are multi-band.&lt;br /&gt;
&lt;br /&gt;
=== Other wire antenna designs ===&lt;br /&gt;
&lt;br /&gt;
A comprehensive source of designs can be found at the QSL hobby and amateur radio site&amp;lt;ref&amp;gt;https://www.qsl.net/va3iul/Antenna/Wire%2520Antennas%2520for%2520Ham%2520Radio/Wire_antennas_for_ham_radio.htm&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== Wavelength calculation ===&lt;br /&gt;
&lt;br /&gt;
[[File:Wavelength-calculation.jpg|thumb|left]]&lt;br /&gt;
&lt;br /&gt;
If you know what frequency you need to tune into, you can calculate the full wavelength and build an antenna to match. The wavelength calculation is shown in the inline image.&lt;br /&gt;
&lt;br /&gt;
Here, &#039;v&#039; is called the phase speed (magnitude of the phase velocity) of the wave and &#039;f&#039; is the wave&#039;s frequency&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/Wavelength&amp;lt;/ref&amp;gt;. In the context of radio, &#039;v&#039; is the speed of light, or 3×10&amp;lt;sup&amp;gt;8&amp;lt;/sup&amp;gt; m/s (specifically 299,792,458 m/s). For instance, if the desired emergency broadcast station was at 12MHz, the full wavelength λ would be 24.98 meters (81.95 feet). From this calculation a fully functional 1/2 wavelength antenna of 12.5 meters (41 feet) could be built.&lt;br /&gt;
&lt;br /&gt;
== Receivers, transceivers and tuners ==&lt;br /&gt;
&lt;br /&gt;
[[File:Transceiver.png|thumb|240px|A modern HF transceiver with a spectrum analyzer and DSP capabilities]]&lt;br /&gt;
To work with specialist and custom antennae a receiver will be needed. Unless the antenna is built with precision to listen to a particular signal, a tuner will be needed. If broadcast is also desired, a transmitter will be required. In radio terminology, a device that both transmits (TX) and receives (RX) is a &#039;transceiver. &lt;br /&gt;
Dedicated all-in-one transceivers can vary greatly in price and features, and depending on the region the operator is in, are bound to local broadcasting laws. Typically a HAM (Hobby and Amateur Radio) license is required to operate them.&lt;br /&gt;
&lt;br /&gt;
An all-in-one transceiver is recommended for those with little technical knowledge. Most can be quickly learned reading their respective technical documentation. A more technical but in some cases less inexpensive option is discussed below.&lt;br /&gt;
&lt;br /&gt;
=== Software Defined Radio ===&lt;br /&gt;
&lt;br /&gt;
[[File:Rtl-sdr.jpg|thumb|left|Four RTL-SDR devices, two of them with the popular SMA style brass connectors, used to interface with antenna. Note the writing on pink tape on one citing that device&#039;s particular parts-per-million clock offset, referenced by the operator when preparing the device for use.]]&lt;br /&gt;
&lt;br /&gt;
In recent years, Software Defined Radio (SDR) has emerged as a practical and accessible alternative to dedicated hardware radio transceivers and receivers. Software Defined Radio implements a software interface to tunable radio hardware, such that reception and broadcasts can be done and processed entirely in software. This gives great flexibility to the operator, even so far as allowing for them to build their own tuners, signal de-modulators and broadcasting stations.&lt;br /&gt;
&lt;br /&gt;
Software Defined Radio is a large topic, and will not be covered in depth here. Should the reader be interested in exploring building transceivers in an SDR context, both the BladeRF and HackRF are interesting hardware options to look at. A comprehensive list of SDRs can be found here&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/List_of_software-defined_radios&amp;lt;/ref&amp;gt;. SDRs are typically interfaced with GNUradio or another software radio programming environment&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/GNU_Radio&amp;lt;/ref&amp;gt;. Every feature and facet of a modern dedicated hardware transceiver can be implemented in software on a laptop or workstation.&lt;br /&gt;
&lt;br /&gt;
[[File:Full-wave-loop-listeners.jpg|thumb|right|240px|Radio enthusiasts in Aotearoa New Zealand listening to an AM radio broadcast from Austria, received on a 20M Full Wave Loop wire antenna connected to an RTL-SDR tuned by the GQRX software]]&lt;br /&gt;
 &lt;br /&gt;
An inexpensive option for those wishing to build a quality receiver for their long-range antenna project is working with RTL-SDR devices and compatible tuners. RTL-SDR devices are low-cost digital video tuner (DVB-T) USB sticks using the Realtek RTL2832U controller that can be repurposed for receiving a broad spectrum of radio signal&amp;lt;ref&amp;gt;https://www.rtl-sdr.com/&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Some RTL-SDR models will provide reception from 500 kHz up to 1.75 GHz. For those wishing to work with lower signals, for instance in the MW, an &#039;upconverter&#039; can be used. A popular upconverter is the Nooelec &#039;Ham it up&#039;.&lt;br /&gt;
&lt;br /&gt;
The RTL-SDR project is maintained by a radio enthusiast group called Osmocom&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/Osmocom&amp;lt;/ref&amp;gt;. RTL-SDR drivers exist for GNU/Linux, Windows and OS X, and can be tuned with several different popular interfaces. One of them, which is recommended for beginners, is the cross platform visual tuner and de-modulator GQRX&amp;lt;ref&amp;gt;https://gqrx.dk/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
When working with RTL-SDR devices it is important to use a reference tone to determine the amount of &#039;clock shift&#039; (in parts-per-million) that the device in use has, and shift it using your chosen tool before use. This is due to the lower quality of the clock (used to tune) on these devices. They will differ from device to device.&lt;br /&gt;
&lt;br /&gt;
=== Offline networking with radio ===&lt;br /&gt;
&lt;br /&gt;
Computer controlled radio platforms such as LoRaWAN can be used to provide for sending text and other data over a mesh network. Please see [https://wiki.collapsible.systems/Offline_networking Offline Networking] for more.&lt;br /&gt;

&lt;div&gt;== Introduction ==&lt;br /&gt;
&lt;br /&gt;
Offline and off-grid networking broadly refers to the practice of sharing information between devices without use of the global Internet. The advantage of this in a disaster scenario is to provide a fallback for access to critical information and communication services in cases where reaching the Internet is not possible. This can be done with a device acting as a WiFi access point and router, LoRaWAN devices sharing information over long distances using the LoRa radio specification, or with a digital radio service known as &#039;&#039;packet radio&#039;&#039;. Each of these will be covered here.&lt;br /&gt;
&lt;br /&gt;
== WiFi ==&lt;br /&gt;
&lt;br /&gt;
WiFi (or Wi-Fi) refers to a collection of wireless protocols from the 802.11 collection of standards. WiFi is predominantly used for low power, short range networking, and centers around 2 popular bands, 2.4GHz and the faster 5GHz&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/Wi-Fi&amp;lt;/ref&amp;gt;. In 2019, it was found more than 3.05 billion Wi-Fi-enabled devices are shipped globally each year&amp;lt;ref&amp;gt;https://www.researchandmarkets.com/reports/5135535/global-wi-fi-enabled-devices-shipment-forecast&amp;lt;/ref&amp;gt;. Each of these devices can connect to any wireless access point which is open, or for which they are authenticated. This presents a significant opportunity for the distribution of critical information where Internet access is otherwise not available.&lt;br /&gt;
&lt;br /&gt;
=== Offline WiFi access points ===&lt;br /&gt;
&lt;br /&gt;
Due to our habitual relationship with WiFi and connecting to the public Internet, we can often overlook WiFi&#039;s applications in &#039;offline&#039; contexts. A a WiFi access point (AP) does not need the public Internet to provide access to content, if the content is locally accessible to the AP. In such applications, either the WiFi router itself holds the data (perhaps on a USB stick), or the data is served from another device connected directly to the AP. &lt;br /&gt;
&lt;br /&gt;
==== OpenWrt ====&lt;br /&gt;
&lt;br /&gt;
Some commercial routers provide ability for file sharing across their network using the factory firmware installed on the device. However in the majority of applications, an &#039;&#039;after market&#039;&#039; firmware is used, like OpenWrt&amp;lt;ref&amp;gt;https://openwrt.org&amp;lt;/ref&amp;gt;. OpenWrt is an open source project and community dedicated to writing and testing firmware that can be &#039;flashed&#039; onto scavenged or bought WiFi routers, providing them with new functionality and customisation options. At the time of writing, 2043 wireless access points are supported by OpenWrt to some degree&amp;lt;ref&amp;gt;https://openwrt.org/toh/start&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Many projects have been done exploring the practical application of offline networking in a wireless context using OpenWrt. However, many small form-factor computers can be repurposed as WiFi access points, that either route through to another network (like the Internet) or remain hermetic. &lt;br /&gt;
&lt;br /&gt;
For those more technically inclined, any GNU/Linux laptop or device with a wireless network adapter can be repurposed as a wireless access point serving information and files from a locally hosted website. A popular webserver for use in such contexts is &#039;&#039;lighttpd&#039;&#039;. A popular daemon/service providing access point functionality is &#039;&#039;hostapd&#039;&#039;, often coupled with &#039;&#039;dnsmasq&#039;&#039; to provide automatic network configuration of clients using the DHCP protocol alongside domain name resolution&amp;lt;ref&amp;gt;https://w1.fi/hostapd/&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;https://dnsmasq.org/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== WiFi mesh networks ==&lt;br /&gt;
[[File:Berliner freifunk netz 03-01-2007.jpg|thumb|Image showing connections between nodes of the Freifunk network in Berlin in 2007.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Mesh networks are computer networks that have in-built node redundancy, meaning that no central node is critical to the distribution of information across the network. Routing algorithms ensure that if a node is unavailable along the route, another optimised route is chosen. Mesh networks are in wide use throughout military and disaster response applications, but can also be deployed and managed by civilians with low cost equipment.&lt;br /&gt;
&lt;br /&gt;
A low power mesh network run by a community atop dumpster-dived/recycled or bought wireless routers could provide a valuable means of distributing mission-critical information where [[Cellular communications|cellular infrastructure]] or the public Internet is otherwise unavailable.&lt;br /&gt;
&lt;br /&gt;
=== Freifunk ===&lt;br /&gt;
&lt;br /&gt;
Among the most well known and successful WiFi mesh networks in the world is Freifunk. Established in 2003 in Germany, one of the primary goals of the project is to build a large-scale free wireless Wi-Fi network that is decentralized, free of discrimination (net neutrality), owned by those who run it, and to support local communication independent of the public Internet&amp;lt;ref&amp;gt;https://freifunk.net/en/&amp;lt;/ref&amp;gt;. Comprising over 41,000 wireless access points run by civilians, the Freifunk firmware is based atop OpenWrt and runs the &#039;&#039;batman-adv&#039;&#039; (B.A.T.M.A.N) mesh networking protocol, which is actively developed by Freifunk activists&amp;lt;ref&amp;gt;https://openwrt.org/docs/guide-user/network/wifi/mesh/batman&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
The Freifunk firmware can be freely downloaded and modified to be deployed anywhere&amp;lt;ref&amp;gt;https://wiki.freifunk.net/Freifunk-Firmware&amp;lt;/ref&amp;gt;(DE).&lt;br /&gt;
&lt;br /&gt;
=== Red Hook WiFi ===&lt;br /&gt;
&lt;br /&gt;
Red Hook Wifi was established in Red Hook, Brooklyn, New York City in 2011&amp;lt;ref&amp;gt;https://redhookwifi.org/&amp;lt;/ref&amp;gt;. It was created by the Red Hook Initiative to provide access to broadband for the regions many residents. A survey found that many people in the area accessed the internet primarily through mobile phones and that over 30% of the population did not have broadband access at home. &amp;lt;ref&amp;gt;https://urbanomnibus.net/2013/09/red-hook-wifi/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Red Hook serves as an excellent example of community-run infrastructure serving a critically important role in an environmental emergency. In 2012, when Hurricane Sandy hit the region, Internet and cellular communications systems were down&amp;lt;ref&amp;gt;http://nymag.com/intelligencer/2017/10/what-happens-to-the-internet-after-a-disaster.html&amp;lt;/ref&amp;gt;. During this crisis the Red Hook mesh network not only remained active, but the Red Hook headquarters became a hub for volunteer coordination and food distribution, and residents came to the Red Hook Initiative&#039;s office to charge their devices and connect to the internet&amp;lt;ref&amp;gt;https://www.nycedc.com/blog-entry/rising-challenge-red-hook-initiative&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;https://www.forbes.com/sites/deannazandt/2012/11/10/what-sandy-has-taught-us-about-technology-relief-and-resilience/#4db1984f5947&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Soon after Hurricane Sandy hit, the Federal Emergency Management Agency of the United States connected itself to the Red Hook Network, providing a satellite uplink, connecting itself, the Red Cross and residents such that they could find out about food banks, shelters and emergency information&amp;lt;ref&amp;gt;https://www.smh.com.au/technology/meshnets-serve-communities-when-internet-fails-20140515-zrdqe.html&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== SubNodes ===&lt;br /&gt;
&lt;br /&gt;
SubNodes, by Berlin-based artist Sarah Grant, employs popular &#039;&#039;Raspberry Pi&#039;&#039; minicomputers as wireless access points, serving a website and chat application &amp;lt;ref&amp;gt;http://subnodes.org/&amp;lt;/ref&amp;gt;. Smartphones, for instance, can be used to connect to the access point, from which is served a website, alongside simple chat application. The project provides complete instructions requiring minimal prior knowledge for deploying a &#039;SubNode&#039;. Such &#039;SubNodes&#039; could be employed inside weatherproof plastic cases, like tupperware or a plastic lunchbox, powered off solar power bank or voltage-converted car battery, and used to provide valuable information without need for the Internet. SubNodes can also be used in a mesh networking capacity, connecting to other compatible nodes.&lt;br /&gt;
&lt;br /&gt;
=== Other mesh networks by region === &lt;br /&gt;
&lt;br /&gt;
Wikipedia hosts a page dedicated to listing mesh networks by region&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/List_of_wireless_community_networks_by_region&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== LoRa/LoRaWAN ==&lt;br /&gt;
[[File:Adafruit-lora-rpi.jpg|thumb|120px|right|An Adafruit LoRa shield atop a Rasberry Pi Model 4, with 900MHz omnidirectional antenna.]]&lt;br /&gt;
&lt;br /&gt;
[[File:Meshtastic-Station-G2 .jpg|thumb|240px|left|A Meshtastic Station G2 LoRa mesh networking device with attached omnidirectional 900MHz antenna]]&lt;br /&gt;
&lt;br /&gt;
LoRa (from &#039;long range&#039;) is a communication protocol that allows for the transmitting and receiving of data in license-free portions of the radio spectrum. Together with LoRaWAN, it represents is an interesting low cost, low power, wide area networking platform, that can be used to create robust mesh networks. Mobility, end-to-end security and location are all features implemented by the LoRa architecture. While the data rate of LoRa is significantly smaller than that of [[Cellular communications|cellular]] or wireless networks, operating from 0.3 kbit/s to 50 kbit/s per channel, it is sufficient for a diverse applications such as the sending of location information, messages and chat, status updates, sensor output, etc. The longest 2-way conversation between LoRa devices using less than 1 Watt of power is 206 km (128 miles)&amp;lt;ref&amp;gt;https://hackaday.com/2023/06/26/meshtastic-for-the-greater-good/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
One practical mobile application of LoRa is MsgLab, where it is employed as a small handset with keyboard and case such that it can be used for texting in off-grid contexts&amp;lt;ref&amp;gt;https://www.msglab.co/&amp;lt;/ref&amp;gt;. The Meshtastic project is another, with a large global community of user-operated mesh nodes. This off-the-shelf solution provides a modular platform whereby LoRa hardware, battery, and case and antenna are purchased, a web-based flasher is used to deploy the software onto the hardware. Various interfaces to the hardware (including apps and web-based) are provided. Meshtastic can be a good solution for resilient communications for those less technical, allowing messages to be sent from a paired smartphone over bluetooth to the device, the messages of which are in turn either broadcast to a public channel on the mesh, or to a user-configured encrypted channel of devices on the mesh (for instance to devices of friends and family in the region).&amp;lt;ref&amp;gt;https://meshtastic.org/&amp;lt;/ref&amp;gt;. A global map of Meshtastic nodes can be seen [https://meshtastic.liamcottle.net/ here].&lt;br /&gt;

Each of these will be covered here.&lt;br /&gt;
&lt;br /&gt;
== WiFi ==&lt;br /&gt;
&lt;br /&gt;
WiFi (or Wi-Fi) refers to a collection of wireless protocols from the 802.11 collection of standards. WiFi is predominantly used for low power, short range networking, and centers around 2 popular bands, 2.4GHz and the faster 5GHz&amp;lt;ref&amp;gt;https://en.wikipedia.org/wiki/Wi-Fi&amp;lt;/ref&amp;gt;. In 2019, it was found more than 3.05 billion Wi-Fi-enabled devices are shipped globally each year&amp;lt;ref&amp;gt;https://www.researchandmarkets.com/reports/5135535/global-wi-fi-enabled-devices-shipment-forecast&amp;lt;/ref&amp;gt;. Each of these devices can connect to any wireless access point which is open, or for which they are authenticated. This presents a significant opportunity for the distribution of critical information where Internet access is otherwise not available.&lt;br /&gt;
&lt;br /&gt;
=== Offline WiFi access points ===&lt;br /&gt;
&lt;br /&gt;
Due to our habitual relationship with WiFi and connecting to the public Internet, we can often overlook WiFi&#039;s applications in &#039;offline&#039; contexts. A a WiFi access point (AP) does not need the public Internet to provide access to content, if the content is locally accessible to the AP. In such applications, either the WiFi router itself holds the data (perhaps on a USB stick), or the data is served from another device connected directly to the AP. &lt;br /&gt;
&lt;br /&gt;
==== OpenWrt ====&lt;br /&gt;
&lt;br /&gt;
Some commercial routers provide ability for file sharing across their network using the factory firmware installed on the device. However in the majority of applications, an &#039;&#039;after market&#039;&#039; firmware is used, like OpenWrt&amp;lt;ref&amp;gt;https://openwrt.org&amp;lt;/ref&amp;gt;. OpenWrt is an open source project and community dedicated to writing and testing firmware that can be &#039;flashed&#039; onto scavenged or bought WiFi routers, providing them with new functionality and customisation options. At the time of writing, 2043 wireless access points are supported by OpenWrt to some degree&amp;lt;ref&amp;gt;https://openwrt.org/toh/start&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Many projects have been done exploring the practical application of offline networking in a wireless context using OpenWrt. However, many small form-factor computers can be repurposed as WiFi access points, that either route through to another network (like the Internet) or remain hermetic. &lt;br /&gt;
&lt;br /&gt;
For those more technically inclined, any GNU/Linux laptop or device with a wireless network adapter can be repurposed as a wireless access point serving information and files from a locally hosted website. A popular webserver for use in such contexts is &#039;&#039;lighttpd&#039;&#039;. A popular daemon/service providing access point functionality is &#039;&#039;hostapd&#039;&#039;, often coupled with &#039;&#039;dnsmasq&#039;&#039; to provide automatic network configuration of clients using the DHCP protocol alongside domain name resolution&amp;lt;ref&amp;gt;https://w1.fi/hostapd/&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;https://dnsmasq.org/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== WiFi mesh networks ==&lt;br /&gt;
[[File:Berliner freifunk netz 03-01-2007.jpg|thumb|Image showing connections between nodes of the Freifunk network in Berlin in 2007.]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Mesh networks are computer networks that have in-built node redundancy, meaning that no central node is critical to the distribution of information across the network. Routing algorithms ensure that if a node is unavailable along the route, another optimised route is chosen. Mesh networks are in wide use throughout military and disaster response applications, but can also be deployed and managed by civilians with low cost equipment.&lt;br /&gt;
&lt;br /&gt;
A low power mesh network run by a community atop dumpster-dived/recycled or bought wireless routers could provide a valuable means of distributing mission-critical information where [[Cellular communications|cellular infrastructure]] or the public Internet is otherwise unavailable.&lt;br /&gt;
&lt;br /&gt;
=== Freifunk ===&lt;br /&gt;
&lt;br /&gt;
Among the most well known and successful WiFi mesh networks in the world is Freifunk. Established in 2003 in Germany, one of the primary goals of the project is to build a large-scale free wireless Wi-Fi network that is decentralized, free of discrimination (net neutrality), owned by those who run it, and to support local communication independent of the public Internet&amp;lt;ref&amp;gt;https://freifunk.net/en/&amp;lt;/ref&amp;gt;. Comprising over 41,000 wireless access points run by civilians, the Freifunk firmware is based atop OpenWrt and runs the &#039;&#039;batman-adv&#039;&#039; (B.A.T.M.A.N) mesh networking protocol, which is actively developed by Freifunk activists&amp;lt;ref&amp;gt;https://openwrt.org/docs/guide-user/network/wifi/mesh/batman&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
The Freifunk firmware can be freely downloaded and modified to be deployed anywhere&amp;lt;ref&amp;gt;https://wiki.freifunk.net/Freifunk-Firmware&amp;lt;/ref&amp;gt;(DE).&lt;br /&gt;
&lt;br /&gt;
=== Red Hook WiFi ===&lt;br /&gt;
&lt;br /&gt;
Red Hook Wifi was established in Red Hook, Brooklyn, New York City in 2011&amp;lt;ref&amp;gt;https://redhookwifi.org/&amp;lt;/ref&amp;gt;. It was created by the Red Hook Initiative to provide access to broadband for the regions many residents. A survey found that many people in the area accessed the internet primarily through mobile phones and that over 30% of the population did not have broadband access at home. &amp;lt;ref&amp;gt;https://urbanomnibus.net/2013/09/red-hook-wifi/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Red Hook serves as an excellent example of community-run infrastructure serving a critically important role in an environmental emergency. In 2012, when Hurricane Sandy hit the region, Internet and cellular communications systems were down&amp;lt;ref&amp;gt;http://nymag.com/intelligencer/2017/10/what-happens-to-the-internet-after-a-disaster.html&amp;lt;/ref&amp;gt;. During this crisis the Red Hook mesh network not only remained active, but the Red Hook headquarters became a hub for volunteer coordination and food distribution, and residents came to the Red Hook Initiative&#039;s office to charge their devices and connect to the internet&amp;lt;ref&amp;gt;https://www.nycedc.com/blog-entry/rising-challenge-red-hook-initiative&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;https://www.forbes.com/sites/deannazandt/2012/11/10/what-sandy-has-taught-us-about-technology-relief-and-resilience/#4db1984f5947&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Soon after Hurricane Sandy hit, the Federal Emergency Management Agency of the United States connected itself to the Red Hook Network, providing a satellite uplink, connecting itself, the Red Cross and residents such that they could find out about food banks, shelters and emergency information&amp;lt;ref&amp;gt;https://www.smh.com.au/technology/meshnets-serve-communities-when-internet-fails-20140515-zrdqe.html&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== SubNodes ===&lt;br /&gt;
&lt;br /&gt;
SubNodes, by Berlin-based artist Sarah Grant, employs popular &#039;&#039;Raspberry Pi&#039;&#039; minicomputers as wireless access points, serving a website and chat application &amp;lt;ref&amp;gt;http://subnodes.org/&amp;lt;/ref&amp;gt;. Smartphones, for instance, can be used to connect to the access point, from which is served a website, alongside simple chat application. The project provides complete instructions requiring minimal prior knowledge for deploying a &#039;SubNode&#039;. Such &#039;SubNodes&#039; could be employed inside weatherproof plastic cases, like tupperware or a plastic lunchbox, powered off solar power bank or voltage-converted car battery, and used to provide valuable information without need for the Internet. SubNodes can also be used in a mesh networking capacity, connecting to other compatible nodes.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
LoRa (from &#039;long range&#039;) is a communication protocol that allows for the transmitting and receiving of data in license-free portions of the radio spectrum. Together with LoRaWAN, it represents is an interesting low cost, low power, wide area networking platform, that can be used to create robust mesh networks. Mobility, end-to-end security and location are all features implemented by the LoRa architecture. While the data rate of LoRa is significantly smaller than that of [[Cellular communications|cellular]] or wireless networks, operating from 0.3 kbit/s to 50 kbit/s per channel, it is sufficient for a diverse applications such as the sending of location information, messages and chat, status updates, sensor output, etc. The longest 2-way conversation between LoRa devices using less than 1 Watt of power is 206 km (128 miles)&amp;lt;ref&amp;gt;https://hackaday.com/2023/06/26/meshtastic-for-the-greater-good/&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
One practical mobile application of LoRa is MsgLab, where it is employed as a small handset with keyboard and case such that it can be used for texting in off-grid contexts&amp;lt;ref&amp;gt;https://www.msglab.co/&amp;lt;/ref&amp;gt;. The Meshtastic project is another, with a large global community of user-operated mesh nodes. This off-the-shelf solution provides a modular platform whereby LoRa hardware, battery, and case and antenna are purchased, a web-based flasher is used to deploy the software onto the hardware. Various interfaces to the hardware (including apps and web-based) are provided. Meshtastic can be a good solution for resilient communications for those less technical, allowing messages to be sent from a paired smartphone over bluetooth to the device, the messages of which are in turn either broadcast to a public channel on the mesh, or to a user-configured encrypted channel of devices on the mesh (for instance to devices of friends and family in the region).&amp;lt;ref&amp;gt;https://meshtastic.org/&amp;lt;/ref&amp;gt;. A global map of Meshtastic nodes can be seen [https://meshtastic.liamcottle.net/ here].&lt;br /&gt;

&lt;div&gt;== Introduction ==&lt;br /&gt;
&lt;br /&gt;
Offline and off-grid networking broadly refers to the practice of sharing information between devices without use of the global Internet. The advantage of this in a disaster scenario is to provide a fallback for access to critical information and communication services in cases where reaching the Internet is not possible. This can be done with a device acting as a WiFi access point and router, LoRaWAN devices sharing information over long distances using the LoRa radio specification, or with a digital radio service known as &#039;&#039;packet radio&#039;&#039;.

&lt;hr /&gt;
&lt;div&gt;Permacomputing is both a concept and a community of practice oriented around issues of [[resilience]] and regenerativity in computer and network technology inspired by permaculture.&lt;br /&gt;
&lt;br /&gt;
In a time where computing epitomizes [[industrial waste]], permacomputing encourages the maximizing of hardware lifespans, minimizing energy use and focusing on the use of already available computational resources. We do this we want to find out how we can practice good relations with the Earth by learning from ecological systems to leverage and re-center existing technologies and practices. We are also interested in investigating what a permacomputing way of life could be, and what sort of transformative computational culture and aesthetics it could bring forward.&lt;br /&gt;
&lt;br /&gt;
Create low-power systems that strengthens the biosphere and use the wide-area network sparingly. Minimize the use of artificial energy, fossil fuels and mineral resources. Don&#039;t create systems that obfuscate waste.&lt;br /&gt;

==== Simple Critical Infrastructure Maps ====&lt;br /&gt;
&lt;br /&gt;
&amp;quot;Simple Critical Infrastructure Maps is a Creative Commons licenced mapping and analysis tool for evaluating personal and social resilience. It is intended to be used for planning, and is simple enough to learn during a crisis to facilitate cooperation and effective response.&amp;quot;&lt;br /&gt;

==== Flock Radio Messaging System ====&lt;br /&gt;
&lt;br /&gt;
&amp;quot;Flock and Peep protocols for Arduino-style MCUs.&lt;br /&gt;
&lt;br /&gt;
Flock is a non-hierarchical, self-negotiating radio messaging protocol. Flock (and Peep) protocols are entirely timer-based. It is designed to carry message payloads, which consist of keyword::number pairs, with a heavy emphasis event signaling.&lt;br /&gt;
&lt;br /&gt;
The code is contained in a single (library) object that contains the Flock/Peep protocol logic, which in turn loads the NRF24L01+ driver module. This code requires an event-loop style coding scheme. All of the code is non-blocking. It&#039;s fairly lightweight, and runs fine on an Uno (Atmega328).&amp;quot;&lt;br /&gt;

		<summary type="html">&lt;p&gt;Julian: /* Example group item list */&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;==Introduction==&lt;br /&gt;
&lt;br /&gt;
A Go Bag or Go Kit (sometimes known in the USA as &#039;Bug Out Bag&#039;) is a single bag or backpack that contains essential items when you need to suddenly leave your location. Because geographical and even political environments differ so much, there is no single go-bag solution to fit all applications. There are however items necessary to every Go Bag, regardless of context.&lt;br /&gt;
&lt;br /&gt;
Building up a Go Bag is rarely a project done in a rush, not only because it&#039;s rare that all the items needed are already at hand. Rather, thought, planning and perhaps even budgeting is required. Following a &#039;recipe&#039; online or buying a pre-made Go Bag kit is not advised, as you may find that it does not meet the needs of you and those you care about when you need it to. Further, almost every Go Bag outline popularised is for a single individual, rather than groups, rarely accounting for those with special needs, like the differently abled, children and elderly. For this reason, sometimes a &#039;Go Bag&#039; comprises more than one bag, carrying items to support the needs of a group, and where heavier bags are carried by those physically stronger in that group.&lt;br /&gt;
&lt;br /&gt;
==Planning your Go Bag(s)==&lt;br /&gt;
&lt;br /&gt;
Take time to sit down with those in your community and make lists of needs. Invoke the thought experiment of suddenly having to leave in a hurry, thinking about daily routines and dependencies and imagining trying to meet those needs with no guarantee of shelter, shops, electricity, mobile telephony and the Internet, even a toilet. Make the imagined duration at least 3 full days. You will likely find that the list of dependencies is longer than you think.&lt;br /&gt;
&lt;br /&gt;
Here is a generic example of essential needs and supplies for a single individual for 3 days of instability:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|+ Needs table 3 days&lt;br /&gt;
|-&lt;br /&gt;
! Needs !! Item !! Critical || Expires&lt;br /&gt;
|-&lt;br /&gt;
| Hydration || 3L of drinking water, water filter || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food || Dehydrated or dry food or canned food || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food preparation tools || Camping stove, pot, plate or bowl || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Fuel || Gas or fuel blocks, foraged wood || N || Y&lt;br /&gt;
|-&lt;br /&gt;
| Shelter || Tent or improvised tarpaulin || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Bedding || Sleeping bag or blanket || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Light || Torch and batteries, mobile phone, headlamp || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Medical needs || Medicines || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Toilet needs and hygiene || Toilet paper or wipes, hand sanitiser and/or soap, sanitary pads || Y || Y &lt;br /&gt;
|-&lt;br /&gt;
| Clothing || Clothing, raincoat, 2 changes of underwear || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency information || Radio and batteries, mobile phone (if network) || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency signal || Whistle, mirror, torch, Personal Locator Beacon || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Emergency communication || Mobile phone (if network), walkie talkie charged batteries || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Identification || Passport and/or driver&#039;s license, medical documents || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Money || Cash || N || Y&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Note there are likely other needs for members of your community not met by the above list. Mobility support, like a wheelchair or crutch, may be one example, as is an oxygen tank and mask for someone with challenged breathing. Pets and their needs will need to be considered also. &lt;br /&gt;
&lt;br /&gt;
==== Needs example: Family of 5 ====&lt;br /&gt;
&lt;br /&gt;
A family of two parents, their two children and their grandmother.&lt;br /&gt;
&lt;br /&gt;
* Parent 1: Migrainer, takes prescription medicines&lt;br /&gt;
* Parent 2: Short sighted, glasses and contact lenses&lt;br /&gt;
* Grandmother: Arthritic knee, uses crutch. Gluten-intolerant&lt;br /&gt;
* Child 1: allergic to bees, needs antihistamine&lt;br /&gt;
* Child 2: diabetic, takes insulin&lt;br /&gt;
&lt;br /&gt;
=== Example group item list ===&lt;br /&gt;
&lt;br /&gt;
The below (draft) list is intended as a generic yet comprehensive guide for groups of up to 5 or so people providing 3 days of support. These items would be organised into bags to support both group and individual needs. A large 75L Backpack carried by the strongest person(s) in the group can carry items for the whole group, alongside their own personal items.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
=== Size and weight considerations ===&lt;br /&gt;
The bags chosen should be suitable to meet the size of the contents inside. The physically strongest and most able in the group should carry the heaviest bags with items for the whole group, with the weakest and least able carrying the lightest or none at all. All should carry their own ID and a day&#039;s rations of food in the event they are separated from the group.&lt;br /&gt;
&lt;br /&gt;
Backpacks of the sort used for camping make a better choice for Go Bags than a suitcase or hand-held bag as they are designed to carry weight on the hips and free up the arms. Much more weight can be carried with such bags, which may be critical if it is required that you need to walk by foot for long periods. Further, backpacks have compartments and pockets designed around easy and rapid access to essentials, and as such help you organise your bag around priorities, while also protecting the important and more vulnerable items. Many backpacks also have rain covers which can be pulled out and stretched over the whole pack, keeping it dry in wet weather. &lt;br /&gt;
&lt;br /&gt;
Children can use their school bags as Go Bags. In it should be enough to keep them warm, dried fruits and other healthy snacks, their ID, phone, a torch and anything to comfort them such as a favourite stuffed toy or book.&lt;br /&gt;
&lt;br /&gt;
== Protecting contents ==&lt;br /&gt;
&lt;br /&gt;
In an environmental or other disaster the conditions you and your gear are exposed to can change suddenly. As a result, it is important that you consider what the elements can do to the contents you depend upon.&lt;br /&gt;
&lt;br /&gt;
==== Water and humidity ====&lt;br /&gt;
&lt;br /&gt;
[[File:Dry bag.jpg|thumb|A &#039;dry bag&#039; can be a good option for keeping many items dry at once, then placed into the larger backpack.]]&lt;br /&gt;
&lt;br /&gt;
Identification papers, cash, toilet paper and towel, a change of clothing all need to be protected from humidity. For the purposes of waterproofing, protect what you need to imagining that the entire Go Bag can be briefly submersed in water. Solutions to dry storage:&lt;br /&gt;
&lt;br /&gt;
* Quality zip-lock plastic bags. Typically transparent, can help you quickly find what you need&lt;br /&gt;
* Diving and ocean &#039;dry bags&#039; with roll-over clips. Can hold and keep dry many items&lt;br /&gt;
* Simple large trash bag, rolled several times and taped. Can be done in a hurry if above items not available&lt;br /&gt;
* Plastic container with screw-top lid. A used plastic vitamin bottle or similar is robust and is a good solution for medicines and other small items&lt;br /&gt;
&lt;br /&gt;
==== Fire ====&lt;br /&gt;
&lt;br /&gt;
It may be that you are forced to move through an area with sparks or flame. For this reason highly flammable and vulnerable items should not be exposed in exterior pockets of your Go Bag. This includes medicines, identification papers but also, importantly, fuel for gas cookers or cigarette lighters and other gas based fire-starters.&lt;br /&gt;
&lt;br /&gt;
==== Theft ====&lt;br /&gt;
&lt;br /&gt;
[[File:Money belt.jpeg|thumb|A money belt can be used to hold cash, some medicines and identity papers | left]]&lt;br /&gt;
&lt;br /&gt;
It may be that you share transport or are walking with people you do not know. Items like cash and identity papers can become targets for theft in such circumstances. Similarly, an exposed knife can be taken from a pocket on worn backpack and used as a weapon. For these reasons, it is important that cash, knives, medicines and identity papers are not sitting in available exposed pockets and so easily accessed by someone that wants them.&lt;br /&gt;
&lt;br /&gt;
Another contingency to consider is that the whole back is stolen. For this reason critical items like identity papers, cash and medicines can be best stored on the body itself, rather than inside the backpack. A water resistant &#039;money belt&#039; that sits under clothing can mitigate for such a situation.&lt;/div&gt;</summary>

&lt;div&gt;==Introduction==&lt;br /&gt;
&lt;br /&gt;
A Go Bag or Go Kit (sometimes known in the USA as &#039;Bug Out Bag&#039;) is a single bag or backpack that contains essential items when you need to suddenly leave your location. Because geographical and even political environments differ so much, there is no single go-bag solution to fit all applications. There are however items necessary to every Go Bag, regardless of context.&lt;br /&gt;
&lt;br /&gt;
Building up a Go Bag is rarely a project done in a rush, not only because it&#039;s rare that all the items needed are already at hand. Rather, thought, planning and perhaps even budgeting is required. Following a &#039;recipe&#039; online or buying a pre-made Go Bag kit is not advised, as you may find that it does not meet the needs of you and those you care about when you need it to. Further, almost every Go Bag outline popularised is for a single individual, rather than groups, rarely accounting for those with special needs, like the differently abled, children and elderly. For this reason, sometimes a &#039;Go Bag&#039; comprises more than one bag, carrying items to support the needs of a group, and where heavier bags are carried by those physically stronger in that group.&lt;br /&gt;
&lt;br /&gt;
==Planning your Go Bag(s)==&lt;br /&gt;
&lt;br /&gt;
Take time to sit down with those in your community and make lists of needs. Invoke the thought experiment of suddenly having to leave in a hurry, thinking about daily routines and dependencies and imagining trying to meet those needs with no guarantee of shelter, shops, electricity, mobile telephony and the Internet, even a toilet. Make the imagined duration at least 3 full days. You will likely find that the list of dependencies is longer than you think.&lt;br /&gt;
&lt;br /&gt;
Here is a generic example of essential needs and supplies for a single individual for 3 days of instability:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|+ Needs table 3 days&lt;br /&gt;
|-&lt;br /&gt;
! Needs !! Item !! Critical || Expires&lt;br /&gt;
|-&lt;br /&gt;
| Hydration || 3L of drinking water, water filter || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food || Dehydrated or dry food or canned food || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food preparation tools || Camping stove, pot, plate or bowl || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Fuel || Gas or fuel blocks, foraged wood || N || Y&lt;br /&gt;
|-&lt;br /&gt;
| Shelter || Tent or improvised tarpaulin || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Bedding || Sleeping bag or blanket || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Light || Torch and batteries, mobile phone, headlamp || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Medical needs || Medicines || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Toilet needs and hygiene || Toilet paper or wipes, hand sanitiser and/or soap, sanitary pads || Y || Y &lt;br /&gt;
|-&lt;br /&gt;
| Clothing || Clothing, raincoat, 2 changes of underwear || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency information || Radio and batteries, mobile phone (if network) || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency signal || Whistle, mirror, torch, Personal Locator Beacon || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Emergency communication || Mobile phone (if network), walkie talkie charged batteries || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Identification || Passport and/or driver&#039;s license, medical documents || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Money || Cash || N || Y&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Note there are likely other needs for members of your community not met by the above list. Mobility support, like a wheelchair or crutch, may be one example, as is an oxygen tank and mask for someone with challenged breathing. Pets and their needs will need to be considered also. &lt;br /&gt;
&lt;br /&gt;
==== Needs example: Family of 5 ====&lt;br /&gt;
&lt;br /&gt;
A family of two parents, their two children and their grandmother.&lt;br /&gt;
&lt;br /&gt;
* Parent 1: Migrainer, takes prescription medicines&lt;br /&gt;
* Parent 2: Short sighted, glasses and contact lenses&lt;br /&gt;
* Grandmother: Arthritic knee, uses crutch. Gluten-intolerant&lt;br /&gt;
* Child 1: allergic to bees, needs antihistamine&lt;br /&gt;
* Child 2: diabetic, takes insulin&lt;br /&gt;
&lt;br /&gt;
=== Example group item list ===&lt;br /&gt;
&lt;br /&gt;
The below (draft) list is intended as a generic yet comprehensive guide for groups of up to 5 or so people providing 3 days of support. These items would be organised into bags to support both group and individual needs. A large 75L Backpack carried by the strongest person(s) in the group can carry items for the whole group, alongside their own personal items.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

|-&lt;br /&gt;

|-&lt;br /&gt;
| Essential medications in screw top plastic bottles and/or zip-lock bags || || X&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
=== Size and weight considerations ===&lt;br /&gt;
The bags chosen should be suitable to meet the size of the contents inside. The physically strongest and most able in the group should carry the heaviest bags with items for the whole group, with the weakest and least able carrying the lightest or none at all. All should carry their own ID and a day&#039;s rations of food in the event they are separated from the group.&lt;br /&gt;
&lt;br /&gt;
Backpacks of the sort used for camping make a better choice for Go Bags than a suitcase or hand-held bag as they are designed to carry weight on the hips and free up the arms. Much more weight can be carried with such bags, which may be critical if it is required that you need to walk by foot for long periods. Further, backpacks have compartments and pockets designed around easy and rapid access to essentials, and as such help you organise your bag around priorities, while also protecting the important and more vulnerable items. Many backpacks also have rain covers which can be pulled out and stretched over the whole pack, keeping it dry in wet weather. &lt;br /&gt;
&lt;br /&gt;
Children can use their school bags as Go Bags. In it should be enough to keep them warm, dried fruits and other healthy snacks, their ID, phone, a torch and anything to comfort them such as a favourite stuffed toy or book.&lt;br /&gt;
&lt;br /&gt;
== Protecting contents ==&lt;br /&gt;
&lt;br /&gt;
In an environmental or other disaster the conditions you and your gear are exposed to can change suddenly. As a result, it is important that you consider what the elements can do to the contents you depend upon.&lt;br /&gt;
&lt;br /&gt;
==== Water and humidity ====&lt;br /&gt;
&lt;br /&gt;
[[File:Dry bag.jpg|thumb|A &#039;dry bag&#039; can be a good option for keeping many items dry at once, then placed into the larger backpack.]]&lt;br /&gt;
&lt;br /&gt;

This includes medicines, identification papers but also, importantly, fuel for gas cookers or cigarette lighters and other gas based fire-starters.&lt;br /&gt;
&lt;br /&gt;

Many backpacks also have rain covers which can be pulled out and stretched over the whole pack, keeping it dry in wet weather. &lt;br /&gt;
&lt;br /&gt;
Children can use their school bags as Go Bags. In it should be enough to keep them warm, dried fruits and other healthy snacks, their ID, phone, a torch and anything to comfort them such as a favourite stuffed toy or book.&lt;br /&gt;
&lt;br /&gt;
== Protecting contents ==&lt;br /&gt;
&lt;br /&gt;
In an environmental or other disaster the conditions you and your gear are exposed to can change suddenly. As a result, it is important that you consider what the elements can do to the contents you depend upon.&lt;br /&gt;
&lt;br /&gt;
==== Water and humidity ====&lt;br /&gt;
&lt;br /&gt;
[[File:Dry bag.jpg|thumb|A &#039;dry bag&#039; can be a good option for keeping many items dry at once, then placed into the larger backpack.]]&lt;br /&gt;
&lt;br /&gt;
Identification papers, cash, toilet paper and towel, a change of clothing all need to be protected from humidity. For the purposes of waterproofing, protect what you need to imagining that the entire Go Bag can be briefly submersed in water. Solutions to dry storage:&lt;br /&gt;
&lt;br /&gt;
* Quality zip-lock plastic bags. Typically transparent, can help you quickly find what you need&lt;br /&gt;
* Diving and ocean &#039;dry bags&#039; with roll-over clips. Can hold and keep dry many items&lt;br /&gt;
* Simple large trash bag, rolled several times and taped. Can be done in a hurry if above items not available&lt;br /&gt;
* Plastic container with screw-top lid. A used plastic vitamin bottle or similar is robust and is a good solution for medicines and other small items&lt;br /&gt;
&lt;br /&gt;
==== Fire ====&lt;br /&gt;
&lt;br /&gt;
It may be that you are forced to move through an area with sparks or flame. For this reason highly flammable and vulnerable items should not be exposed in exterior pockets of your Go Bag. This includes medicines, identification papers but also, importantly, fuel for gas cookers or cigarette lighters and other gas based fire-starters.&lt;br /&gt;
&lt;br /&gt;
==== Theft ====&lt;br /&gt;
&lt;br /&gt;
[[File:Money belt.jpeg|thumb|A money belt can be used to hold cash, some medicines and identity papers | left]]&lt;br /&gt;
&lt;br /&gt;
It may be that you share transport or are walking with people you do not know. Items like cash and identity papers can become targets for theft in such circumstances. Similarly, an exposed knife can be taken from a pocket on worn backpack and used as a weapon. For these reasons, it is important that cash, knives, medicines and identity papers are not sitting in available exposed pockets and so easily accessed by someone that wants them.&lt;br /&gt;
&lt;br /&gt;
Another contingency to consider is that the whole back is stolen. For this reason critical items like identity papers, cash and medicines can be best stored on the body itself, rather than inside the backpack. A water resistant &#039;money belt&#039; that sits under clothing can mitigate for such a situation.&lt;/div&gt;</summary>

&lt;hr /&gt;
&lt;div&gt;==Introduction==&lt;br /&gt;
&lt;br /&gt;
A Go Bag or Go Kit (sometimes known in the USA as &#039;Bug Out Bag&#039;) is a single bag or backpack that contains essential items when you need to suddenly leave your location. Because geographical and even political environments differ so much, there is no single go-bag solution to fit all applications. There are however items necessary to every Go Bag, regardless of context.&lt;br /&gt;
&lt;br /&gt;
Building up a Go Bag is rarely a project done in a rush, not only because it&#039;s rare that all the items needed are already at hand. Rather, thought, planning and perhaps even budgeting is required. Following a &#039;recipe&#039; online or buying a pre-made Go Bag kit is not advised, as you may find that it does not meet the needs of you and those you care about when you need it to. Further, almost every Go Bag outline popularised is for a single individual, rather than groups, rarely accounting for those with special needs, like the differently abled, children and elderly. For this reason, sometimes a &#039;Go Bag&#039; comprises more than one bag, carrying items to support the needs of a group, and where heavier bags are carried by those physically stronger in that group.&lt;br /&gt;
&lt;br /&gt;
==Planning your Go Bag(s)==&lt;br /&gt;
&lt;br /&gt;
Take time to sit down with those in your community and make lists of needs. Invoke the thought experiment of suddenly having to leave in a hurry, thinking about daily routines and dependencies and imagining trying to meet those needs with no guarantee of shelter, shops, electricity, mobile telephony and the Internet, even a toilet. Make the imagined duration at least 3 full days. You will likely find that the list of dependencies is longer than you think.&lt;br /&gt;
&lt;br /&gt;
Here is a generic example of essential needs and supplies for a single individual for 3 days of instability:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|+ Needs table 3 days&lt;br /&gt;
|-&lt;br /&gt;
! Needs !! Item !! Critical || Expires&lt;br /&gt;
|-&lt;br /&gt;
| Hydration || 3L of drinking water, water filter || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food || Dehydrated or dry food or canned food || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food preparation tools || Camping stove, pot, plate or bowl || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Fuel || Gas or fuel blocks, foraged wood || N || Y&lt;br /&gt;
|-&lt;br /&gt;
| Shelter || Tent or improvised tarpaulin || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Bedding || Sleeping bag or blanket || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Light || Torch and batteries, mobile phone, headlamp || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Medical needs || Medicines || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Toilet needs and hygiene || Toilet paper or wipes, hand sanitiser and/or soap, sanitary pads || Y || Y &lt;br /&gt;
|-&lt;br /&gt;
| Clothing || Clothing, raincoat, 2 changes of underwear || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency information || Radio and batteries, mobile phone (if network) || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency signal || Whistle, mirror, torch, Personal Locator Beacon || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Emergency communication || Mobile phone (if network), walkie talkie charged batteries || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Identification || Passport and/or driver&#039;s license, medical documents || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Money || Cash || N || Y&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Note there are likely other needs for members of your community not met by the above list. Mobility support, like a wheelchair or crutch, may be one example, as is an oxygen tank and mask for someone with challenged breathing. Pets and their needs will need to be considered also. &lt;br /&gt;
&lt;br /&gt;
==== Needs example: Family of 5 ====&lt;br /&gt;
&lt;br /&gt;
A family of two parents, their two children and their grandmother.&lt;br /&gt;
&lt;br /&gt;
* Parent 1: Migrainer, takes prescription medicines&lt;br /&gt;
* Parent 2: Short sighted, glasses and contact lenses&lt;br /&gt;
* Grandmother: Arthritic knee, uses crutch. Gluten-intolerant&lt;br /&gt;
* Child 1: allergic to bees, needs antihistamine&lt;br /&gt;
* Child 2: diabetic, takes insulin&lt;br /&gt;
&lt;br /&gt;
=== Example group item list ===&lt;br /&gt;
&lt;br /&gt;
The below (draft) list is intended as a generic yet comprehensive guide for groups of up to 5 or so people providing 3 days of support. These items would be organised into bags to support both group and individual needs. A large 75L Backpack carried by the strongest person(s) in the group can carry items for the whole group, alongside their own personal items.&lt;br /&gt;
&lt;br /&gt;

|-&lt;br /&gt;
| Essential medications in screw top plastic bottles and/or zip-lock bags || || X&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
=== Size and weight considerations ===&lt;br /&gt;
The bags chosen should be suitable to meet the size of the contents inside. The physically strongest and most able in the group should carry the heaviest bags with items for the whole group, with the weakest and least able carrying the lightest or none at all. All should carry their own ID and a day&#039;s rations of food in the event they are separated from the group.&lt;br /&gt;
&lt;br /&gt;
Backpacks of the sort used for camping make a better choice for Go Bags than a suitcase or hand-held bag as they are designed to carry weight on the hips and free up the arms. Much more weight can be carried with such bags, which may be critical if it is required that you need to walk by foot for long periods. Further, backpacks have compartments and pockets designed around easy and rapid access to essentials, and as such help you organise your bag around priorities, while also protecting the important and more vulnerable items. Many backpacks also have rain covers which can be pulled out and stretched over the whole pack, keeping it dry in wet weather. &lt;br /&gt;
&lt;br /&gt;
Children can use their school bags as Go Bags. In it should be enough to keep them warm, dried fruits and other healthy snacks, their ID, phone, a torch and anything to comfort them such as a favourite stuffed toy or book.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
In an environmental or other disaster the conditions you and your gear are exposed to can change suddenly. As a result, it is important that you consider what the elements can do to the contents you depend upon.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
[[File:Dry bag.jpg|thumb|A &#039;dry bag&#039; can be a good option for keeping many items dry at once, then placed into the larger backpack.]]&lt;br /&gt;

=== Size and weight considerations ===&lt;br /&gt;
The bags chosen should be suitable to meet the size of the contents inside. The physically strongest and most able in the group should carry the heaviest bags with items for the whole group, with the weakest and least able carrying the lightest or none at all. All should carry their own ID and a day&#039;s rations of food in the event they are separated from the group.&lt;br /&gt;
&lt;br /&gt;
Backpacks of the sort used for camping make a better choice for Go Bags than a suitcase or hand-held bag as they are designed to carry weight on the hips and free up the arms. Much more weight can be carried with such bags, which may be critical if it is required that you need to walk by foot for long periods. Further, backpacks have compartments and pockets designed around easy and rapid access to essentials, and as such help you organise your bag around priorities, while also protecting the important and more vulnerable items. Many backpacks also have rain covers which can be pulled out and stretched over the whole pack, keeping it dry in wet weather. &lt;br /&gt;
&lt;br /&gt;
Children can use their school bags as Go Bags. In it should be enough to keep them warm, dried fruits and other healthy snacks, their ID, phone, a torch and anything to comfort them such as a favourite stuffed toy or book.&lt;br /&gt;
&lt;br /&gt;
=== Protecting contents ===&lt;br /&gt;
&lt;br /&gt;
In an environmental or other disaster the conditions you and your gear are exposed to can change suddenly. As a result, it is important that you consider what the elements can do to the contents you depend upon.&lt;br /&gt;
&lt;br /&gt;
==== Water and humidity ====&lt;br /&gt;
&lt;br /&gt;
[[File:Dry bag.jpg|thumb|A &#039;dry bag&#039; can be a good option for keeping many items dry at once, then placed into the larger backpack.]]&lt;br /&gt;
&lt;br /&gt;
Identification papers, cash, toilet paper and towel, a change of clothing all need to be protected from humidity. For the purposes of waterproofing, protect what you need to imagining that the entire Go Bag can be briefly submersed in water. Solutions to dry storage:&lt;br /&gt;
&lt;br /&gt;
* Quality zip-lock plastic bags. Typically transparent, can help you quickly find what you need&lt;br /&gt;
* Diving and ocean &#039;dry bags&#039; with roll-over clips. Can hold and keep dry many items&lt;br /&gt;
* Simple large trash bag, rolled several times and taped. Can be done in a hurry if above items not available&lt;br /&gt;
* Plastic container with screw-top lid. A used plastic vitamin bottle or similar is robust and is a good solution for medicines and other small items&lt;br /&gt;
&lt;br /&gt;
==== Fire ====&lt;br /&gt;
&lt;br /&gt;
It may be that you are forced to move through an area with sparks or flame. For this reason highly flammable and vulnerable items should not be exposed in exterior pockets of your Go Bag. This includes medicines, identification papers but also, importantly, fuel for gas cookers or cigarette lighters and other gas based fire-starters.&lt;br /&gt;
&lt;br /&gt;
==== Theft ====&lt;br /&gt;
&lt;br /&gt;
[[File:Money belt.jpeg|thumb|A money belt can be used to hold cash, some medicines and identity papers | left]]&lt;br /&gt;
&lt;br /&gt;
It may be that you share transport or are walking with people you do not know. Items like cash and identity papers can become targets for theft in such circumstances. Similarly, an exposed knife can be taken from a pocket on worn backpack and used as a weapon. For these reasons, it is important that cash, knives, medicines and identity papers are not sitting in available exposed pockets and so easily accessed by someone that wants them.&lt;br /&gt;
&lt;br /&gt;
Another contingency to consider is that the whole back is stolen. For this reason critical items like identity papers, cash and medicines can be best stored on the body itself, rather than inside the backpack. A water resistant &#039;money belt&#039; that sits under clothing can mitigate for such a situation.&lt;/div&gt;</summary>

&lt;div&gt;==Introduction==&lt;br /&gt;
&lt;br /&gt;
A Go Bag or Go Kit (sometimes known in the USA as &#039;Bug Out Bag&#039;) is a single bag or backpack that contains essential items when you need to suddenly leave your location. Because geographical and even political environments differ so much, there is no single go-bag solution to fit all applications. There are however items necessary to every Go Bag, regardless of context.&lt;br /&gt;
&lt;br /&gt;
Building up a Go Bag is rarely a project done in a rush, not only because it&#039;s rare that all the items needed are already at hand. Rather, thought, planning and perhaps even budgeting is required. Following a &#039;recipe&#039; online or buying a pre-made Go Bag kit is not advised, as you may find that it does not meet the needs of you and those you care about when you need it to. Further, almost every Go Bag outline popularised is for a single individual, rather than groups, rarely accounting for those with special needs, like the differently abled, children and elderly. For this reason, sometimes a &#039;Go Bag&#039; comprises more than one bag, carrying items to support the needs of a group, and where heavier bags are carried by those physically stronger in that group.&lt;br /&gt;
&lt;br /&gt;
==Planning your Go Bag(s)==&lt;br /&gt;
&lt;br /&gt;
Take time to sit down with those in your community and make lists of needs. Invoke the thought experiment of suddenly having to leave in a hurry, thinking about daily routines and dependencies and imagining trying to meet those needs with no guarantee of shelter, shops, electricity, mobile telephony and the Internet, even a toilet. Make the imagined duration at least 3 full days. You will likely find that the list of dependencies is longer than you think.&lt;br /&gt;
&lt;br /&gt;
Here is a generic example of essential needs and supplies for a single individual for 3 days of instability:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|+ Needs table 3 days&lt;br /&gt;
|-&lt;br /&gt;
! Needs !! Item !! Critical || Expires&lt;br /&gt;
|-&lt;br /&gt;
| Hydration || 3L of drinking water, water filter || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food || Dehydrated or dry food or canned food || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food preparation tools || Camping stove, pot, plate or bowl || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Fuel || Gas or fuel blocks, foraged wood || N || Y&lt;br /&gt;
|-&lt;br /&gt;
| Shelter || Tent or improvised tarpaulin || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Bedding || Sleeping bag or blanket || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Light || Torch and batteries, mobile phone, headlamp || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Medical needs || Medicines || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Toilet needs and hygiene || Toilet paper or wipes, hand sanitiser and/or soap, sanitary pads || Y || Y &lt;br /&gt;
|-&lt;br /&gt;
| Clothing || Clothing, raincoat, 2 changes of underwear || Y || Y&lt;br /&gt;
|-&lt;br /&gt;

|-&lt;br /&gt;

|-&lt;br /&gt;
| Money || Cash || N || Y&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Note there are likely other needs for members of your community not met by the above list. Mobility support, like a wheelchair or crutch, may be one example, as is an oxygen tank and mask for someone with challenged breathing. Pets and their needs will need to be considered also. &lt;br /&gt;
&lt;br /&gt;
==== Needs example: Family of 5 ====&lt;br /&gt;
&lt;br /&gt;
A family of two parents, their two children and their grandmother.&lt;br /&gt;
&lt;br /&gt;
* Parent 1: Migrainer, takes prescription medicines&lt;br /&gt;
* Parent 2: Short sighted, glasses and contact lenses&lt;br /&gt;
* Grandmother: Arthritic knee, uses crutch. Gluten-intolerant&lt;br /&gt;
* Child 1: allergic to bees, needs antihistamine&lt;br /&gt;
* Child 2: diabetic, takes insulin&lt;br /&gt;
&lt;br /&gt;

The physically strongest and most able in the group should carry the heaviest bags with items for the whole group, with the weakest and least able carrying the lightest or none at all. All should carry their own ID and a day&#039;s rations of food in the event they are separated from the group.&lt;br /&gt;
&lt;br /&gt;
Backpacks of the sort used for camping make a better choice for Go Bags than a suitcase or hand-held bag as they are designed to carry weight on the hips and free up the arms. Much more weight can be carried with such bags, which may be critical if it is required that you need to walk by foot for long periods. Further, backpacks have compartments and pockets designed around easy and rapid access to essentials, and as such help you organise your bag around priorities, while also protecting the important and more vulnerable items. Many backpacks also have rain covers which can be pulled out and stretched over the whole pack, keeping it dry in wet weather. &lt;br /&gt;
&lt;br /&gt;
Children can use their school bags as Go Bags. In it should be enough to keep them warm, dried fruits and other healthy snacks, their ID, phone, a torch and anything to comfort them such as a favourite stuffed toy or book.&lt;br /&gt;
&lt;br /&gt;
=== Protecting contents ===&lt;br /&gt;
&lt;br /&gt;
In an environmental or other disaster the conditions you and your gear are exposed to can change suddenly. As a result, it is important that you consider what the elements can do to the contents you depend upon.&lt;br /&gt;
&lt;br /&gt;
==== Water and humidity ====&lt;br /&gt;
&lt;br /&gt;
[[File:Dry bag.jpg|thumb|A &#039;dry bag&#039; can be a good option for keeping many items dry at once, then placed into the larger backpack.]]&lt;br /&gt;
&lt;br /&gt;
Identification papers, cash, toilet paper and towel, a change of clothing all need to be protected from humidity. For the purposes of waterproofing, protect what you need to imagining that the entire Go Bag can be briefly submersed in water. Solutions to dry storage:&lt;br /&gt;
&lt;br /&gt;
* Quality zip-lock plastic bags. Typically transparent, can help you quickly find what you need&lt;br /&gt;
* Diving and ocean &#039;dry bags&#039; with roll-over clips. Can hold and keep dry many items&lt;br /&gt;
* Simple large trash bag, rolled several times and taped. Can be done in a hurry if above items not available&lt;br /&gt;
* Plastic container with screw-top lid. A used plastic vitamin bottle or similar is robust and is a good solution for medicines and other small items&lt;br /&gt;
&lt;br /&gt;
==== Fire ====&lt;br /&gt;
&lt;br /&gt;
It may be that you are forced to move through an area with sparks or flame. For this reason highly flammable and vulnerable items should not be exposed in exterior pockets of your Go Bag. This includes medicines, identification papers but also, importantly, fuel for gas cookers or cigarette lighters and other gas based fire-starters.&lt;br /&gt;
&lt;br /&gt;
==== Theft ====&lt;br /&gt;
&lt;br /&gt;
[[File:Money belt.jpeg|thumb|A money belt can be used to hold cash, some medicines and identity papers | left]]&lt;br /&gt;
&lt;br /&gt;
It may be that you share transport or are walking with people you do not know. Items like cash and identity papers can become targets for theft in such circumstances. Similarly, an exposed knife can be taken from a pocket on worn backpack and used as a weapon. For these reasons, it is important that cash, knives, medicines and identity papers are not sitting in available exposed pockets and so easily accessed by someone that wants them.&lt;br /&gt;
&lt;br /&gt;
Another contingency to consider is that the whole back is stolen. For this reason critical items like identity papers, cash and medicines can be best stored on the body itself, rather than inside the backpack. A water resistant &#039;money belt&#039; that sits under clothing can mitigate for such a situation.&lt;/div&gt;</summary>

&lt;div&gt;==Introduction==&lt;br /&gt;
&lt;br /&gt;
A Go Bag or Go Kit (sometimes known in the USA as &#039;Bug Out Bag&#039;) is a single bag or backpack that contains essential items when you need to suddenly leave your location. Because geographical and even political environments differ so much, there is no single go-bag solution to fit all applications. There are however items necessary to every Go Bag, regardless of context.&lt;br /&gt;
&lt;br /&gt;
Building up a Go Bag is rarely a project done in a rush, not only because it&#039;s rare that all the items needed are already at hand. Rather, thought, planning and perhaps even budgeting is required. Following a &#039;recipe&#039; online or buying a pre-made Go Bag kit is not advised, as you may find that it does not meet the needs of you and those you care about when you need it to. Further, almost every Go Bag outline popularised is for a single individual, rather than groups, rarely accounting for those with special needs, like the differently abled, children and elderly. For this reason, sometimes a &#039;Go Bag&#039; comprises more than one bag, carrying items to support the needs of a group, and where heavier bags are carried by those physically stronger in that group.&lt;br /&gt;
&lt;br /&gt;
==Planning your Go Bag(s)==&lt;br /&gt;
&lt;br /&gt;
Take time to sit down with those in your community and make lists of needs. Invoke the thought experiment of suddenly having to leave in a hurry, thinking about daily routines and dependencies and imagining trying to meet those needs with no guarantee of shelter, shops, electricity, mobile telephony and the Internet, even a toilet. Make the imagined duration at least 3 full days. You will likely find that the list of dependencies is longer than you think.&lt;br /&gt;
&lt;br /&gt;
Here is a generic example of essential needs and supplies for a single individual for 3 days of instability:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|+ Needs table 3 days&lt;br /&gt;
|-&lt;br /&gt;
! Needs !! Item !! Critical || Expires&lt;br /&gt;
|-&lt;br /&gt;
| Hydration || 3L of drinking water, water filter || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food || Dehydrated or dry food or canned food || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food preparation tools || Camping stove, pot, plate or bowl || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Fuel || Gas or fuel blocks, foraged wood || N || Y&lt;br /&gt;
|-&lt;br /&gt;
| Shelter || Tent or improvised tarpaulin || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Bedding || Sleeping bag or blanket || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Light || Torch and batteries, mobile phone, headlamp || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Medical needs || Medicines || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Toilet needs and hygiene || Toilet paper or wipes, hand sanitiser and/or soap, sanitary pads || Y || Y &lt;br /&gt;
|-&lt;br /&gt;
| Clothing || Clothing, raincoat, 2 changes of underwear || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency information || Radio and batteries, mobile phone (if network) || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency signal || Whistle, mirror, torch, Personal Locator Beacon || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Emergency communication || Mobile phone (if network), walkie talkie charged batteries || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Identification || Passport and/or driver&#039;s license, medical documents || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Money || Cash || N || Y&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Note there are likely other needs for members of your community not met by the above list. Mobility support, like a wheelchair or crutch, may be one example, as is an oxygen tank and mask for someone with challenged breathing. Pets and their needs will need to be considered also. &lt;br /&gt;
&lt;br /&gt;
==== Needs example: Family of 5 ====&lt;br /&gt;
&lt;br /&gt;
A family of two parents, their two children and their grandmother.&lt;br /&gt;
&lt;br /&gt;
* Parent 1: Migrainer, takes prescription medicines&lt;br /&gt;
* Parent 2: Short sighted, glasses and contact lenses&lt;br /&gt;
* Grandmother: Arthritic knee, uses crutch. Gluten-intolerant&lt;br /&gt;
* Child 1: allergic to bees, needs antihistamine&lt;br /&gt;
* Child 2: diabetic, takes insulin&lt;br /&gt;
&lt;br /&gt;

More weight can be carried which may be critical if it is required that you need to walk by food for long periods. Further, such bags have compartments and pockets designed around easy and rapid access to essentials, and as such help you organise your bag around priorities, while also protecting the important and more vulnerable items. The physically strongest and most able in the group should carry the heaviest bags with items for the whole group, with the weakest and least able carrying the lightest or none at all.

&lt;br /&gt;
=== Protecting contents ===&lt;br /&gt;
&lt;br /&gt;
In an environmental or other disaster the conditions you and your gear are exposed to can change suddenly. As a result, it is important that you consider what the elements can do to the contents you depend upon.&lt;br /&gt;
&lt;br /&gt;
==== Water and humidity ====&lt;br /&gt;
&lt;br /&gt;
[[File:Dry bag.jpg|thumb|A &#039;dry bag&#039; can be a good option for keeping many items dry at once, then placed into the larger backpack.]]&lt;br /&gt;
&lt;br /&gt;
Food in cans can be exposed to humidity, so does not need to be sealed, whereas identification papers, cash, toilet paper and towel do need to be sealed. For the purposes of waterproofing, protect what you need to imagining that the entire Go Bag can be briefly submersed in water. Solutions to dry storage:&lt;br /&gt;
&lt;br /&gt;
* Quality zip-lock plastic bags. Typically transparent, can help you quickly find what you need&lt;br /&gt;
* Diving and ocean &#039;dry bags&#039; with roll-over clips. Can hold and keep dry many items&lt;br /&gt;
* Simple large trash bag, rolled several times and taped. Can be done in a hurry if above items not available&lt;br /&gt;
* Plastic container with screw-top lid. A used plastic vitamin bottle or similar is robust and is a good solution for medicines and other small items&lt;br /&gt;
&lt;br /&gt;
==== Fire ====&lt;br /&gt;
&lt;br /&gt;
It may be that you are forced to move through an area with sparks or flame. For this reason highly flammable and vulnerable items should not be exposed in exterior pockets of your Go Bag. This includes medicines, identification papers but also, importantly, fuel for gas cookers or cigarette lighters and other gas based fire-starters.&lt;br /&gt;
&lt;br /&gt;
==== Theft ====&lt;br /&gt;
&lt;br /&gt;
[[File:Money belt.jpeg|thumb|A money belt can be used to hold cash, some medicines and identity papers | left]]&lt;br /&gt;
&lt;br /&gt;
It may be that you share transport or are walking with people you do not know. Items like cash and identity papers can become targets for theft in such circumstances. Similarly, an exposed knife can be taken from a pocket on worn backpack and used as a weapon. For these reasons, it is important that cash, knives, medicines and identity papers are not sitting in available exposed pockets and so easily accessed by someone that wants them.&lt;br /&gt;
&lt;br /&gt;
Another contingency to consider is that the whole back is stolen. For this reason critical items like identity papers, cash and medicines can be best stored on the body itself, rather than inside the backpack. A water resistant &#039;money belt&#039; that sits under clothing can mitigate for such a situation.&lt;/div&gt;</summary>

&lt;hr /&gt;
&lt;div&gt;==Introduction==&lt;br /&gt;
&lt;br /&gt;
A Go Bag or Go Kit (sometimes known in the USA as &#039;Bug Out Bag&#039;) is a single bag or backpack that contains essential items when you need to suddenly leave your location. Because geographical and even political environments differ so much, there is no single go-bag solution to fit all applications. There are however items necessary to every Go Bag, regardless of context.&lt;br /&gt;
&lt;br /&gt;
Building up a Go Bag is rarely a project done in a rush, not only because it&#039;s rare that all the items needed are already at hand. Rather, thought, planning and perhaps even budgeting is required. Following a &#039;recipe&#039; online or buying a pre-made Go Bag kit is not advised, as you may find that it does not meet the needs of you and those you care about when you need it to. Further, almost every Go Bag outline popularised is for a single individual, rather than groups, rarely accounting for those with special needs, like the differently abled, children and elderly. For this reason, sometimes a &#039;Go Bag&#039; comprises more than one bag, carrying items to support the needs of a group, and where heavier bags are carried by those physically stronger in that group.&lt;br /&gt;
&lt;br /&gt;
==Planning your Go Bag(s)==&lt;br /&gt;
&lt;br /&gt;
Take time to sit down with those in your community and make lists of needs. Invoke the thought experiment of suddenly having to leave in a hurry, thinking about daily routines and dependencies and imagining trying to meet those needs with no guarantee of shelter, shops, electricity, mobile telephony and the Internet, even a toilet. Make the imagined duration at least 3 full days. You will likely find that the list of dependencies is longer than you think.&lt;br /&gt;
&lt;br /&gt;
Here is a generic example of essential needs and supplies for a single individual for 3 days of instability:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|+ Needs table 3 days&lt;br /&gt;
|-&lt;br /&gt;
! Needs !! Item !! Critical || Expires&lt;br /&gt;
|-&lt;br /&gt;
| Hydration || 3L of drinking water, water filter || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food || Dehydrated or dry food or canned food || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food preparation tools || Camping stove, pot, plate or bowl || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Fuel || Gas or fuel blocks, foraged wood || N || Y&lt;br /&gt;
|-&lt;br /&gt;
| Shelter || Tent or improvised tarpaulin || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Bedding || Sleeping bag or blanket || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Light || Torch and batteries, mobile phone, headlamp || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Medical needs || Medicines || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Toilet needs and hygiene || Toilet paper or wipes, hand sanitiser and/or soap, sanitary pads || Y || Y &lt;br /&gt;
|-&lt;br /&gt;
| Clothing || Clothing, raincoat, 2 changes of underwear || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency information || Radio and batteries, mobile phone (if network) || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency signal || Whistle, mirror, torch, Personal Locator Beacon || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Emergency communication || Mobile phone (if network), walkie talkie charged batteries || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Identification || Passport and/or driver&#039;s license, medical documents || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Money || Cash || N || Y&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Note there are likely other needs for members of your community not met by the above list. Mobility support, like a wheelchair or crutch, may be one example, as is an oxygen tank and mask for someone with challenged breathing. Pets and their needs will need to be considered also. &lt;br /&gt;
&lt;br /&gt;
==== Needs example: Family of 5 ====&lt;br /&gt;
&lt;br /&gt;
A family of two parents, their two children and their grandmother.&lt;br /&gt;
&lt;br /&gt;
* Parent 1: Migrainer, takes prescription medicines&lt;br /&gt;
* Parent 2: Short sighted, glasses and contact lenses&lt;br /&gt;
* Grandmother: Arthritic knee, uses crutch. Gluten-intolerant&lt;br /&gt;
* Child 1: allergic to bees, needs antihistamine&lt;br /&gt;
* Child 2: diabetic, takes insulin&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=== Size and weight considerations ===&lt;br /&gt;
Those in the needs list that can be fit into a bag or bags will comprise your local community or family&#039;s Go Bag contents. For this reason, the bag chosen should be suitable to meet the size of the contents inside. Backpacks used for camping make a better choice for Go Bags than a suitcase or hand-held bag as they are designed to carry weight on the hips, freeing up the arms. More weight can be carried which may be critical if it is required that you need to walk by food for long periods. Further, such bags have compartments and pockets designed around easy and rapid access to essentials, and as such help you organise your bag around priorities, while also protecting the important and more vulnerable items. The physically strongest and most able in the group should carry the heaviest bags with items for the whole group, with the weakest and least able carrying the lightest or none at all. All should carry their own ID and a day&#039;s rations of food in the event they are separated from the group.&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
=== Size and weight considerations ===&lt;br /&gt;
Those in the needs list that can be fit into a bag or bags will comprise your local community or family&#039;s Go Bag contents. For this reason, the bag chosen should be suitable to meet the size of the contents inside. Backpacks used for camping make a better choice for Go Bags than a suitcase or hand-held bag as they are designed to carry weight on the hips, freeing up the arms. More weight can be carried which may be critical if it is required that you need to walk by food for long periods. Further, such bags have compartments and pockets designed around easy and rapid access to essentials, and as such help you organise your bag around priorities, while also protecting the important and more vulnerable items. The physically strongest and most able in the group should carry the heaviest bags with items for the whole group, with the weakest and least able carrying the lightest or none at all. All should carry their own ID and a day&#039;s rations of food in the event they are separated from the group.&lt;br /&gt;
&lt;br /&gt;
=== Protecting contents ===&lt;br /&gt;
&lt;br /&gt;
In an environmental or other disaster the conditions you and your gear are exposed to can change suddenly. As a result, it is important that you consider what the elements can do to the contents you depend upon.&lt;br /&gt;
&lt;br /&gt;
==== Water and humidity ====&lt;br /&gt;
&lt;br /&gt;
[[File:Dry bag.jpg|thumb|A &#039;dry bag&#039; can be a good option for keeping many items dry at once, then placed into the larger backpack.]]&lt;br /&gt;
&lt;br /&gt;
Food in cans can be exposed to humidity, so does not need to be sealed, whereas identification papers, cash, toilet paper and towel do need to be sealed. For the purposes of waterproofing, protect what you need to imagining that the entire Go Bag can be briefly submersed in water. Solutions to dry storage:&lt;br /&gt;
&lt;br /&gt;
* Quality zip-lock plastic bags. Typically transparent, can help you quickly find what you need&lt;br /&gt;
* Diving and ocean &#039;dry bags&#039; with roll-over clips. Can hold and keep dry many items&lt;br /&gt;
* Simple large trash bag, rolled several times and taped. Can be done in a hurry if above items not available&lt;br /&gt;
* Plastic container with screw-top lid. A used plastic vitamin bottle or similar is robust and is a good solution for medicines and other small items&lt;br /&gt;
&lt;br /&gt;
==== Fire ====&lt;br /&gt;
&lt;br /&gt;
It may be that you are forced to move through an area with sparks or flame. For this reason highly flammable and vulnerable items should not be exposed in exterior pockets of your Go Bag. This includes medicines, identification papers but also, importantly, fuel for gas cookers or cigarette lighters and other gas based fire-starters.&lt;br /&gt;
&lt;br /&gt;
==== Theft ====&lt;br /&gt;
&lt;br /&gt;
[[File:Money belt.jpeg|thumb|A money belt can be used to hold cash, some medicines and identity papers | left]]&lt;br /&gt;
&lt;br /&gt;
It may be that you share transport or are walking with people you do not know. Items like cash and identity papers can become targets for theft in such circumstances. Similarly, an exposed knife can be taken from a pocket on worn backpack and used as a weapon. For these reasons, it is important that cash, knives, medicines and identity papers are not sitting in available exposed pockets and so easily accessed by someone that wants them.&lt;br /&gt;
&lt;br /&gt;
Another contingency to consider is that the whole back is stolen. For this reason critical items like identity papers, cash and medicines can be best stored on the body itself, rather than inside the backpack. A water resistant &#039;money belt&#039; that sits under clothing can mitigate for such a situation.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;==Introduction==&lt;br /&gt;
&lt;br /&gt;
A Go Bag or Go Kit (sometimes known in the USA as &#039;Bug Out Bag&#039;) is a single bag or backpack that contains essential items when you need to suddenly leave your location. Because geographical and even political environments differ so much, there is no single go-bag solution to fit all applications. There are however items necessary to every Go Bag, regardless of context.&lt;br /&gt;
&lt;br /&gt;
Building up a Go Bag is rarely a project done in a rush, not only because it&#039;s rare that all the items needed are already at hand. Rather, thought, planning and perhaps even budgeting is required. Following a &#039;recipe&#039; online or buying a pre-made Go Bag kit is not advised, as you may find that it does not meet the needs of you and those you care about when you need it to. Further, almost every Go Bag outline popularised is for a single individual, rather than groups, rarely accounting for those with special needs, like the differently abled, children and elderly. For this reason, sometimes a &#039;Go Bag&#039; comprises more than one bag, carrying items to support the needs of a group, and where heavier bags are carried by those physically stronger in that group.&lt;br /&gt;
&lt;br /&gt;
==Planning your Go Bag(s)==&lt;br /&gt;
&lt;br /&gt;
Take time to sit down with those in your community and make lists of needs. Invoke the thought experiment of suddenly having to leave in a hurry, thinking about daily routines and dependencies and imagining trying to meet those needs with no guarantee of shelter, shops, electricity, mobile telephony and the Internet, even a toilet. Make the imagined duration at least 3 full days. You will likely find that the list of dependencies is longer than you think.&lt;br /&gt;
&lt;br /&gt;
Here is a generic example of essential needs and supplies for a single individual for 3 days of instability:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|+ Needs table 3 days&lt;br /&gt;
|-&lt;br /&gt;
! Needs !! Item !! Critical || Expires&lt;br /&gt;
|-&lt;br /&gt;
| Hydration || 3L of drinking water, water filter || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food || Dehydrated or dry food or canned food || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food preparation tools || Camping stove, pot, plate or bowl || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Fuel || Gas or fuel blocks, foraged wood || N || Y&lt;br /&gt;
|-&lt;br /&gt;
| Shelter || Tent or improvised tarpaulin || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Bedding || Sleeping bag or blanket || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Light || Torch and batteries, mobile phone, headlamp || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Medical needs || Medicines || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Toilet needs and hygiene || Toilet paper or wipes, hand sanitiser and/or soap, sanitary pads || Y || Y &lt;br /&gt;
|-&lt;br /&gt;
| Clothing || Clothing, raincoat, 2 changes of underwear || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency information || Radio and batteries, mobile phone (if network) || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency signal || Whistle, mirror, torch, Personal Locator Beacon || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Emergency communication || Mobile phone (if network), walkie talkie charged batteries || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Identification || Passport and/or driver&#039;s license, medical documents || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Money || Cash || N || Y&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Note there are likely other needs for members of your community not met by the above list. Mobility support, like a wheelchair or crutch, may be one example, as is an oxygen tank and mask for someone with challenged breathing. Pets and their needs will need to be considered also. &lt;br /&gt;
&lt;br /&gt;
==== Needs example: Family of 5 ====&lt;br /&gt;
&lt;br /&gt;
A family of two parents, their two children and their grandmother.&lt;br /&gt;
&lt;br /&gt;
* Parent 1: Migrainer, takes prescription medicines&lt;br /&gt;
* Parent 2: Short sighted, glasses and contact lenses&lt;br /&gt;
* Grandmother: Arthritic knee, uses crutch. Gluten-intolerant&lt;br /&gt;
* Child 1: allergic to bees, needs antihistamine&lt;br /&gt;
* Child 2: diabetic, takes insulin&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=== Size and weight considerations ===&lt;br /&gt;
Those in the needs list that can be fit into a bag or bags will comprise your local community or family&#039;s Go Bag contents. For this reason, the bag chosen should be suitable to meet the size of the contents inside. Backpacks used for camping make a better choice for Go Bags than a suitcase or hand-held bag as they are designed to carry weight on the hips, freeing up the arms. More weight can be carried which may be critical if it is required that you need to walk by food for long periods. Further, such bags have compartments and pockets designed around easy and rapid access to essentials, and as such help you organise your bag around priorities, while also protecting the important and more vulnerable items. The physically strongest and most able in the group should carry the heaviest bags with items for the whole group, with the weakest and least able carrying the lightest or none at all. All should carry their own ID and a day&#039;s rations of food in the event they are separated from the group.&lt;br /&gt;
&lt;br /&gt;
=== Protecting contents ===&lt;br /&gt;
&lt;br /&gt;
In an environmental or other disaster the conditions you and your gear are exposed to can change suddenly. As a result, it is important that you consider what the elements can do to the contents you depend upon.&lt;br /&gt;
&lt;br /&gt;
==== Water and humidity ====&lt;br /&gt;
&lt;br /&gt;
[[File:Dry bag.jpg|thumb|A &#039;dry bag&#039; can be a good option for keeping many items dry at once, then placed into the larger backpack.]]&lt;br /&gt;
&lt;br /&gt;
Food in cans can be exposed to humidity, so does not need to be sealed, whereas identification papers, cash, toilet paper and towel do need to be sealed. For the purposes of waterproofing, protect what you need to imagining that the entire Go Bag can be briefly submersed in water. Solutions to dry storage:&lt;br /&gt;
&lt;br /&gt;
* Quality zip-lock plastic bags. Typically transparent, can help you quickly find what you need&lt;br /&gt;
* Diving and ocean &#039;dry bags&#039; with roll-over clips. Can hold and keep dry many items&lt;br /&gt;
* Simple large trash bag, rolled several times and taped. Can be done in a hurry if above items not available&lt;br /&gt;
* Plastic container with screw-top lid. A used plastic vitamin bottle or similar is robust and is a good solution for medicines and other small items&lt;br /&gt;
&lt;br /&gt;
==== Fire ====&lt;br /&gt;
&lt;br /&gt;
It may be that you are forced to move through an area with sparks or flame. For this reason highly flammable and vulnerable items should not be exposed in exterior pockets of your Go Bag. This includes medicines, identification papers but also, importantly, fuel for gas cookers or cigarette lighters and other gas based fire-starters.&lt;br /&gt;
&lt;br /&gt;
==== Theft ====&lt;br /&gt;
&lt;br /&gt;
[[File:Money belt.jpeg|thumb|A money belt can be used to hold cash, some medicines and identity papers | left]]&lt;br /&gt;
&lt;br /&gt;
It may be that you share transport or are walking with people you do not know. Items like cash and identity papers can become targets for theft in such circumstances. Similarly, an exposed knife can be taken from a pocket on worn backpack and used as a weapon. For these reasons, it is important that cash, knives, medicines and identity papers are not sitting in available exposed pockets and so easily accessed by someone that wants them.&lt;br /&gt;
&lt;br /&gt;
Another contingency to consider is that the whole back is stolen. For this reason critical items like identity papers, cash and medicines can be best stored on the body itself, rather than inside the backpack. A water resistant &#039;money belt&#039; that sits under clothing can mitigate for such a situation.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;==Introduction==&lt;br /&gt;
&lt;br /&gt;
A Go Bag or Go Kit (sometimes known in the USA as &#039;Bug Out Bag&#039;) is a single bag or backpack that contains essential items when you need to suddenly leave your location. Because geographical and even political environments differ so much, there is no single go-bag solution to fit all applications. There are however items necessary to every Go Bag, regardless of context.&lt;br /&gt;
&lt;br /&gt;
Building up a Go Bag is rarely a project done in a rush, not only because it&#039;s rare that all the items needed are already at hand. Rather, thought, planning and perhaps even budgeting is required. Following a &#039;recipe&#039; online or buying a pre-made Go Bag kit is not advised, as you may find that it does not meet the needs of you and those you care about when you need it to. Further, almost every Go Bag outline popularised is for a single individual, rather than groups, rarely accounting for those with special needs, like the differently abled, children and elderly. For this reason, sometimes a &#039;Go Bag&#039; comprises more than one bag, carrying items to support the needs of a group, and where heavier bags are carried by those physically stronger in that group.&lt;br /&gt;
&lt;br /&gt;
==Planning your Go Bag(s)==&lt;br /&gt;
&lt;br /&gt;
Take time to sit down with those in your community and make lists of needs. Invoke the thought experiment of suddenly having to leave in a hurry, thinking about daily routines and dependencies and imagining trying to meet those needs with no guarantee of shelter, shops, electricity, mobile telephony and the Internet, even a toilet. Make the imagined duration at least 3 full days. You will likely find that the list of dependencies is longer than you think.&lt;br /&gt;
&lt;br /&gt;
Here is a generic example of essential needs and supplies for a single individual for 3 days of instability:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|+ Needs table 3 days&lt;br /&gt;
|-&lt;br /&gt;
! Needs !! Item !! Critical || Expires&lt;br /&gt;
|-&lt;br /&gt;
| Hydration || 3L of drinking water, water filter || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food || Dehydrated or dry food or canned food || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food preparation tools || Camping stove, pot, plate or bowl || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Fuel || Gas or fuel blocks, foraged wood || N || Y&lt;br /&gt;
|-&lt;br /&gt;
| Shelter || Tent or improvised tarpaulin || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Bedding || Sleeping bag or blanket || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Light || Torch and batteries, mobile phone, headlamp || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Medical needs || Medicines || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Toilet needs and hygiene || Toilet paper or wipes, hand sanitiser and/or soap, sanitary pads || Y || Y &lt;br /&gt;
|-&lt;br /&gt;
| Clothing || Clothing, raincoat, 2 changes of underwear || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency information || Radio and batteries, mobile phone (if network) || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency signal || Whistle, mirror, torch, Personal Locator Beacon || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Emergency communication || Mobile phone (if network), walkie talkie charged batteries || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Identification || Passport and/or driver&#039;s license, medical documents || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Money || Cash || N || Y&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Note there are likely other needs for members of your community not met by the above list. Mobility support, like a wheelchair or crutch, may be one example, as is an oxygen tank and mask for someone with challenged breathing. Pets and their needs will need to be considered also. &lt;br /&gt;
&lt;br /&gt;
==== Needs example: Family of 5 ====&lt;br /&gt;
&lt;br /&gt;
A family of two parents, their two children and their grandmother.&lt;br /&gt;
&lt;br /&gt;
* Parent 1: Migrainer, takes prescription medicines&lt;br /&gt;
* Parent 2: Short sighted, glasses and contact lenses&lt;br /&gt;
* Grandmother: Arthritic knee, uses crutch. Gluten-intolerant&lt;br /&gt;
* Child 1: allergic to bees, needs antihistamine&lt;br /&gt;
* Child 2: diabetic, takes insulin&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=== Size and weight considerations ===&lt;br /&gt;
Those in the needs list that can be fit into a bag or bags will comprise your local community or family&#039;s Go Bag contents. For this reason, the bag chosen should be suitable to meet the size of the contents inside. Backpacks used for camping make a better choice for Go Bags than a suitcase or hand-held bag as they are designed to carry weight on the hips, freeing up the arms. More weight can be carried which may be critical if it is required that you need to walk by food for long periods. Further, such bags have compartments and pockets designed around easy and rapid access to essentials, and as such help you organise your bag around priorities, while also protecting the important and more vulnerable items. The physically strongest and most able in the group should carry the heaviest bags with items for the whole group, with the weakest and least able carrying the lightest or none at all. All should carry their own ID and a day&#039;s rations of food in the event they are separated from the group.&lt;br /&gt;
&lt;br /&gt;
=== Protecting contents ===&lt;br /&gt;
&lt;br /&gt;
In an environmental or other disaster the conditions you and your gear are exposed to can change suddenly. As a result, it is important that you consider what the elements can do to the contents you depend upon.&lt;br /&gt;
&lt;br /&gt;
==== Water and humidity ====&lt;br /&gt;
&lt;br /&gt;
[[File:Dry bag.jpg|thumb|A &#039;dry bag&#039; can be a good option for keeping many items dry at once, then placed into the larger backpack.]]&lt;br /&gt;
&lt;br /&gt;
Food in cans can be exposed to humidity, so does not need to be sealed, whereas identification papers, cash, toilet paper and towel do need to be sealed. For the purposes of waterproofing, protect what you need to imagining that the entire Go Bag can be briefly submersed in water. Solutions to dry storage:&lt;br /&gt;
&lt;br /&gt;
* Quality zip-lock plastic bags. Typically transparent, can help you quickly find what you need&lt;br /&gt;
* Diving and ocean &#039;dry bags&#039; with roll-over clips. Can hold and keep dry many items&lt;br /&gt;
* Simple large trash bag, rolled several times and taped. Can be done in a hurry if above items not available&lt;br /&gt;
* Plastic container with screw-top lid. A used plastic vitamin bottle or similar is robust and is a good solution for medicines and other small items&lt;br /&gt;
&lt;br /&gt;
==== Fire ====&lt;br /&gt;
&lt;br /&gt;
It may be that you are forced to move through an area with sparks or flame. For this reason highly flammable and vulnerable items should not be exposed in exterior pockets of your Go Bag. This includes medicines, identification papers but also, importantly, fuel for gas cookers or cigarette lighters and other gas based fire-starters.&lt;br /&gt;
&lt;br /&gt;
==== Theft ====&lt;br /&gt;
&lt;br /&gt;
[[File:Money belt.jpeg|thumb|A money belt can be used to hold cash, some medicines and identity papers | left]]&lt;br /&gt;
&lt;br /&gt;
It may be that you share transport or are walking with people you do not know. Items like cash and identity papers can become targets for theft in such circumstances. Similarly, an exposed knife can be taken from a pocket on worn backpack and used as a weapon. For these reasons, it is important that cash, knives, medicines and identity papers are not sitting in available exposed pockets and so easily accessed by someone that wants them.&lt;br /&gt;
&lt;br /&gt;
Another contingency to consider is that the whole back is stolen. For this reason critical items like identity papers, cash and medicines can be best stored on the body itself, rather than inside the backpack. A water resistant &#039;money belt&#039; that sits under clothing can mitigate for such a situation.&lt;br /&gt;
&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;==Introduction==&lt;br /&gt;
&lt;br /&gt;
A Go Bag or Go Kit (sometimes known in the USA as &#039;Bug Out Bag&#039;) is a single bag or backpack that contains essential items when you need to suddenly leave your location. Because geographical and even political environments differ so much, there is no single go-bag solution to fit all applications. There are however items necessary to every Go Bag, regardless of context.&lt;br /&gt;
&lt;br /&gt;
Building up a Go Bag is rarely a project done in a rush, not only because it&#039;s rare that all the items needed are already at hand. Rather, thought, planning and perhaps even budgeting is required. Following a &#039;recipe&#039; online or buying a pre-made Go Bag kit is not advised, as you may find that it does not meet the needs of you and those you care about when you need it to. Further, almost every Go Bag outline popularised is for a single individual, rather than groups, rarely accounting for those with special needs, like the differently abled, children and elderly. For this reason, sometimes a &#039;Go Bag&#039; comprises more than one bag, carrying items to support the needs of a group, and where heavier bags are carried by those physically stronger in that group.&lt;br /&gt;
&lt;br /&gt;
==Planning your Go Bag(s)==&lt;br /&gt;
&lt;br /&gt;
Take time to sit down with those in your community and make lists of needs. Invoke the thought experiment of suddenly having to leave in a hurry, thinking about daily routines and dependencies and imagining trying to meet those needs with no guarantee of shelter, shops, electricity, mobile telephony and the Internet, even a toilet. Make the imagined duration at least 3 full days. You will likely find that the list of dependencies is longer than you think.&lt;br /&gt;
&lt;br /&gt;
Here is a generic example of essential needs and supplies for a single individual for 3 days of instability:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|+ Needs table 3 days&lt;br /&gt;
|-&lt;br /&gt;
! Needs !! Item !! Critical || Expires&lt;br /&gt;
|-&lt;br /&gt;
| Hydration || 3L of drinking water, water filter || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food || Dehydrated or dry food or canned food || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Food preparation tools || Camping stove, pot, plate or bowl || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Fuel || Gas or fuel blocks, foraged wood || N || Y&lt;br /&gt;
|-&lt;br /&gt;
| Shelter || Tent or improvised tarpaulin || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Bedding || Sleeping bag or blanket || Y || N&lt;br /&gt;
|-&lt;br /&gt;
| Light || Torch and batteries, mobile phone, headlamp || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Medical needs || Medicines || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Toilet needs and hygiene || Toilet paper or wipes, hand sanitiser and/or soap, sanitary pads || Y || Y &lt;br /&gt;
|-&lt;br /&gt;
| Clothing || Clothing, raincoat, 2 changes of underwear || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency information || Radio and batteries, mobile phone (if network) || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Emergency signal || Whistle, mirror, torch, Personal Locator Beacon || N || N&lt;br /&gt;
|-&lt;br /&gt;
| Emergency communication || Mobile phone (if network), walkie talkie charged batteries || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Identification || Passport and/or driver&#039;s license, medical documents || Y || Y&lt;br /&gt;
|-&lt;br /&gt;
| Money || Cash || N || Y&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Note there are likely other needs for members of your community not met by the above list. Mobility support, like a wheelchair or crutch, may be one example, as is an oxygen tank and mask for someone with challenged breathing. Pets and their needs will need to be considered also. &lt;br /&gt;
&lt;br /&gt;
==== Needs example: Family of 5 ====&lt;br /&gt;
&lt;br /&gt;
A family of two parents, their two children and their grandmother.&lt;br /&gt;
&lt;br /&gt;
* Parent 1: Migrainer, takes prescription medicines&lt;br /&gt;
* Parent 2: Short sighted, glasses and contact lenses&lt;br /&gt;
* Grandmother: Arthritic knee, uses crutch. Gluten-intolerant&lt;br /&gt;
* Child 1: allergic to bees, needs antihistamine&lt;br /&gt;
* Child 2: diabetic, takes insulin&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=== Size and weight considerations ===&lt;br /&gt;
Those in the needs list that can be fit into a bag or bags will comprise your local community or family&#039;s Go Bag contents. For this reason, the bag chosen should be suitable to meet the size of the contents inside. Backpacks used for camping make a better choice for Go Bags than a suitcase or hand-held bag as they are designed to carry weight on the hips, freeing up the arms. More weight can be carried which may be critical if it is required that you need to walk by food for long periods. Further, such bags have compartments and pockets designed around easy and rapid access to essentials, and as such help you organise your bag around priorities, while also protecting the important and more vulnerable items. The physically strongest and most able in the group should carry the heaviest bags with items for the whole group, with the weakest and least able carrying the lightest or none at all. All should carry their own ID and a day&#039;s rations of food in the event they are separated from the group.&lt;br /&gt;
&lt;br /&gt;
=== Protecting contents ===&lt;br /&gt;
&lt;br /&gt;
In an environmental or other disaster the conditions you and your gear are exposed to can change suddenly. As a result, it is important that you consider what the elements can do to the contents you depend upon.&lt;br /&gt;
&lt;br /&gt;
==== Water and humidity ====&lt;br /&gt;
&lt;br /&gt;
[[File:Dry bag.jpg|thumb|A &#039;dry bag&#039; can be a good option for keeping many items dry at once, then placed into the larger backpack.]]&lt;br /&gt;
&lt;br /&gt;
Food in cans can be exposed to humidity, so does not need to be sealed, whereas identification papers, cash, toilet paper and towel do need to be sealed. For the purposes of waterproofing, protect what you need to imagining that the entire Go Bag can be briefly submersed in water. Solutions to dry storage:&lt;br /&gt;
&lt;br /&gt;
* Quality zip-lock plastic bags. Typically transparent, can help you quickly find what you need&lt;br /&gt;
* Diving and ocean &#039;dry bags&#039; with roll-over clips. Can hold and keep dry many items&lt;br /&gt;
* Simple large trash bag, rolled several times and taped. Can be done in a hurry if above items not available&lt;br /&gt;
* Plastic container with screw-top lid. A used plastic vitamin bottle or similar is robust and is a good solution for medicines and other small items&lt;br /&gt;
&lt;br /&gt;
==== Fire ====&lt;br /&gt;
&lt;br /&gt;
It may be that you are forced to move through an area with sparks or flame. For this reason highly flammable and vulnerable items should not be exposed in exterior pockets of your Go Bag. This includes medicines, identification papers but also, importantly, fuel for gas cookers or cigarette lighters and other gas based fire-starters.&lt;br /&gt;
&lt;br /&gt;
==== Theft ====&lt;br /&gt;
&lt;br /&gt;
[[File:Money belt.jpeg|thumb|A money belt can be used to hold cash, some medicines and identity papers | left]]&lt;br /&gt;
&lt;br /&gt;
It may be that you share transport or are walking with people you do not know. Items like cash and identity papers can become targets for theft in such circumstances. Similarly, an exposed knife can be taken from a pocket on worn backpack and used as a weapon. For these reasons, it is important that cash, knives, medicines and identity papers are not sitting in available exposed pockets and so easily accessed by someone that wants them.&lt;br /&gt;
&lt;br /&gt;
Another contingency to consider is that the whole back is stolen. For this reason critical items like identity papers, cash and medicines can be best stored on the body itself, rather than inside the backpack. A water resistant &#039;money belt&#039; that sits under clothing can mitigate for such a situation.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Example Go Bag item list ==&lt;br /&gt;
&lt;br /&gt;
The below (draft) list is intended as a guide for groups providing 3 days of support&lt;br /&gt;
&lt;br /&gt;
* Tent(s), or tarpaulin(s) and rope, or plastic sheeting and rope and/or duct tape (in order of preference)&lt;br /&gt;
* Sleeping bag per person&lt;br /&gt;
* 3L of water per person, sealed in plastic bottles or hiking bladder&lt;br /&gt;
* 1 Water &#039;straw&#039; with carbon filter per group&lt;br /&gt;
* 1 full meal per person per day, plus sealed bought bag of dried fruits per person&lt;br /&gt;
* Camping stove and pot, camping bowls, &#039;spork&#039; (spoon and fork in one) per person&lt;br /&gt;
* First aid kit, including painkillers and sterilisation spray&lt;br /&gt;
* One small traveling towel per person&lt;br /&gt;
* One roll of toilet paper and hand sanitiser, per person&lt;br /&gt;
* One reflective gold/silver rescue blanket per person&lt;br /&gt;
* One full change of clothes per person including warm thermals and hat&lt;br /&gt;
* Raincoat per person&lt;br /&gt;
* Wet bag, strong rubbish/trash bag will do, used for wet clothes that need to be transported&lt;br /&gt;
* Cigarette lighter and/or safety matches in plastic ziplock bag&lt;br /&gt;
* Torch, with fully charged batteries and set of spare batteries (USB charged torches with LiPo batteries better) per person&lt;br /&gt;
* One full tang fixed blade knife for group&lt;br /&gt;
* One small locking folder knife per adult&lt;br /&gt;
* Whistle per person&lt;br /&gt;
* Mobile phone per person&lt;br /&gt;
* Hand held AM/FM radio with retractable antenna and pre-charged batteries&lt;br /&gt;
* Pre-charged USB (minimum 20,000 mAh) power bank, solar banks better&lt;br /&gt;
* Analog compass&lt;/div&gt;</summary>

&lt;hr /&gt;
&lt;div&gt;==Introduction==&lt;br /&gt;
&lt;br /&gt;
A Go Bag or Go Kit (sometimes known in the USA as &#039;Bug Out Bag&#039;) is a single bag or backpack that contains essential items when you need to suddenly leave your location. Because geographical and even political environments differ so much, there is no single go-bag solution to fit all applications. There are however items necessary to every Go Bag, regardless of context.&lt;br /&gt;
&lt;br /&gt;
Building up a Go Bag is rarely a project done in a rush, not only because it&#039;s rare that all the items needed are already at hand. Rather, thought, planning and perhaps even budgeting is required. Following a &#039;recipe&#039; online or buying a pre-made Go Bag kit is not advised, as you may find that it does not meet the needs of you and those you care about when you need it to. Further, almost every Go Bag outline popularised is for a single individual, rather than groups, rarely accounting for those with special needs, like the differently abled, children and elderly. For this reason, sometimes a &#039;Go Bag&#039; comprises more than one bag, carrying items to support the needs of a group, and where heavier bags are carried by those physically stronger in that group.&lt;br /&gt;
&lt;br /&gt;
==Planning your Go Bag(s)==&lt;br /&gt;
&lt;br /&gt;
Take time to sit down with those in your community and make lists of needs. Invoke the thought experiment of suddenly having to leave in a hurry, thinking about daily routines and dependencies and imagining trying to meet those needs with no guarantee of shelter, shops, electricity, mobile telephony and the Internet, even a toilet. Make the imagined duration at least 3 full days. You will likely find that the list of dependencies is longer than you think.&lt;br /&gt;
&lt;br /&gt;
Here is a generic example of essential needs and supplies for a single individual for 3 days of instability:&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
It may be that you share transport or are walking with people you do not know. Items like cash and identity papers can become targets for theft in such circumstances. Similarly, an exposed knife can be taken from a pocket on worn backpack and used as a weapon. For these reasons, it is important that cash, knives, medicines and identity papers are not sitting in available exposed pockets and so easily accessed by someone that wants them.&lt;br /&gt;
&lt;br /&gt;
Another contingency to consider is that the whole back is stolen. For this reason critical items like identity papers, cash and medicines can be best stored on the body itself, rather than inside the backpack. A water resistant &#039;money belt&#039; that sits under clothing can mitigate for such a situation.&lt;br /&gt;
