Meshtastic

Meshtastic is a LoRa-based mesh networking protocol and software platform. The main goal of the project is enabling low-power, long-range communication over ISM radio bands. It transmits at power levels which do not require a license to use. It is designed around exchanging text messages and data in off-grid environments, with potential applications in IoT projects where a decentralized communication system is needed without existing infrastructure. Meshtastic uses LoRa peer to peer (P2P), a long-range radio protocol, to form a mesh network by rebroadcasting messages to extend communication reach. Each device can connect with a single phone, enabling messaging in off-grid areas, making it useful for not only messages, but also data transmission. Meshtastic was created by Kevin Hester in early 2020 as a solution for communication during hobbies where reliable internet access is unavailable. The project operates as a grassroots, community-driven endeavor with established local communities, maintaining a strong DIY ethos. The software is open source, with hundreds of contributors participating in its development.
