The Meshtastic project leverages _LoRa_ radio protocol to establish a long-range, off-grid communication platform, functioning as a decentralized mesh network. It facilitates sending and receiving text messages using inexpensive LoRa radios, eliminating reliance on traditional infrastructure or a smartphone for core mesh communication. Key features include encrypted communication, extended battery life, and optional GPS-based location services, with radios designed to rebroadcast messages to ensure delivery across the mesh. This system has demonstrated a record range of **331km** and is entirely community-driven and open source, with its codebase hosted on GitHub. Unlike conventional amateur radio, Meshtastic operates on LoRa frequencies generally accessible without specific licenses. Each Meshtastic radio can pair with one phone for message exchange, and support is provided by volunteers.
