meshtastic

Meshtastic is an open-source project that enables long-range, off-grid communication using low-power LoRa radios, allowing users to send text messages and location data without cell service or internet. It is designed for outdoor enthusiasts, emergency preparedness groups, and anyone needing resilient, decentralized communication in remote areas. Its appeal lies in creating a user-owned mesh network that is affordable, extensible, and operates independently of existing infrastructure.
