## What is Meshtastic
|
||||
Meshtastic® is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source!
|
||||
|
||||
Meshtastic is an off-grid, encrypted communication platform that runs open source software on affordable radios. These radios rebroadcast messages they receive in order to create a mesh network. The underlying technology, LoRa is a long range radio protocol that is available to most regions without needing certification like ham operators.
|
||||
### Features
|
||||
|
||||
Paired with the Meshtastic companion app, you are able to send and receive encrypted messages on your personal mesh. These radios have low power draw so they have excellent battery life. Perfect for outdoor excursions like backpacking, hiking, paragliding, and skiing where communication can be sparse.
|
||||
- No phone required for node to node communication.
|
||||
- Encrypted communication
|
||||
- Excellent battery life (LoRa radios have a very low power draw)
|
||||
- Send and recieve text messages between members of the mesh
|
||||
- Enable optional GPS based location features
|
||||
- And more!
|
||||
|
||||
Radios can be paired to a single phone so that you're able to message your friends and family, and they can address your specific radio.
|
||||

## How does it work
|
||||
The underlying technology, LoRa is a long range radio protocol that is available to most regions without needing certification like HAM operators.
|
||||
|
||||
The radios automatically rebroadcast messages they receive in order to create a mesh network so that everyone in the group can receive messages - even from the furthest member. Depending on settings used, the Meshtastic mesh can sustain up to 80 device nodes.
|
||||
|
||||
Radios can be paired to a single phone so that your friends and family are able to address a message to your specific radio. Each device supports a connection from a single user at a time.
|
||||
|
||||
<!--- FIXME: too technical for intro ?
|
||||
When you send a message on your Meshtastic companion app, it is relayed to the radio using bluetooth. That message is then broadcast by the radio three times over a certain interval in order to create redundancy for lost packets.
|
||||
|
||||
When a receiving radio captures a packet, it checks to see if it has heard that message before. If it has it ignores the message. If it hasn't heard the message, it will rebroadcast it at a certain interval three times.
|
||||
|
||||
For each message a radio rebroadcasts, it marks the "hop limit" down by one. When a radio receives a packet with a hop limit of zero, it will not rebroadcast the message.
