FresnoMesh is a community-driven initiative dedicated to building a mesh network of solar-powered Meshtastic radios across Fresno, California. This network functions like a city-wide text messaging system, enabling people to communicate publicly or privately with anyone connected. It operates without any external infrastructure—no reliance on the power grid, cell phone towers, or the internet. Think of it like text message walkie talkies.
We're working to set up solar-powered radio repeaters in Fresno. These radios communicate on the 906.875 MHz frequency using the LoRa protocol. The radios mesh using the open-source Meshtastic software. Users can connect to these repeaters by Bluetooth using their phone if they’re close enough, or they can use their own handheld nodes which will also act as repeaters. The messages hop from node to node, extending the reach of the network and ensuring everyone receives every message.
