Meshtastic

Meshtastic is a Mesh Network consisting of low-power, long-range (many miles/km), small communicators. These are little battery-powered boxes that can optionally link to a phone with Bluetooth or Wifi. The communicators form an automatic mesh and can share text messages or GPS coordinates. All traffic on meshtastic is end-to-end Encrypted.

Meshtastic is based on LoRa radios.

A network in which the nodes typically discover each other and the routes between each other automatically.

When things are difficult – maybe there’s been a disaster, or an invasion (this page is being written in 2022 just after Russia invaded Ukraine), or maybe you’re just backpacking off the grid – there are tools that can help you keep in touch, or move your data around. This page aims to survey some of them, roughly in order from easiest to more complex.
