An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices.

Meshtastic® is a project that lets you use inexpensive LoRa radios as a long range off-grid communicator for areas without reliable cellular service. These radios are great for hiking, skiing, paragliding - essentially any hobby where you don't have reliable internet access. Each member of the mesh can send and view text messages and enable optional GPS based location features.
