Core benefits

Everything that makes MeshCore a practical addition to a Sonoma County emergency kit.

No license, no test

Unlike ham radio, MeshCore uses license-free 915 MHz ISM band hardware — anyone in the household can use it immediately, including kids.

Real hill-to-hill range

LoRa radios can cover miles between ridgelines with a good antenna position — useful across Sonoma's valleys and coastal hills.

Runs for days on a battery

Companion nodes sip power and can run over a week on a single charge; repeater nodes can run indefinitely on a small solar panel.

Works without cell or internet

Messages hop device-to-device across the mesh, so the network keeps working through PSPS shutoffs and cell tower outages.

Encrypted messaging

Direct messages and private channels are end-to-end encrypted; public channels let whole neighborhoods coordinate in the open.

Open source & inexpensive

The firmware is MIT-licensed and free; a starter companion node typically runs about $25–$50 in hardware — see meshcore.io.

How it compares

MeshCore isn't a replacement for ham radio or GMRS — it's a low-barrier layer that gets more devices, in more pockets, talking to each other.

Fits alongside Sonoma County's existing networks

MeshCore is designed to complement, not replace, the emergency communications infrastructure Sonoma County already relies on.

Sonoma County GMRS network

The county has deployed roughly 500 handheld GMRS radios and a 14-repeater network covering about 80% of the county for CERT and COPE groups in West County communities. MeshCore gives households a free, complementary text layer. Read the county announcement.

ACS & Sonoma County Radio Amateurs

Sonoma County's Auxiliary Communications Service runs 60+ trained volunteer radio operators under the Department of Emergency Management, working alongside SCRA's ARES and Storm Watch nets. Learn about ACS.

North Bay Communication Cooperative

WiConduit's grassroots North Bay Communication Cooperative already distributes free two-way radios and runs workshops for Sonoma County neighborhoods — a natural fit for adding MeshCore nodes. Visit WiConduit.

North Bay Area Mesh (AREDN)

A separate, ham-radio-based high-speed data mesh (AREDN, not MeshCore) already links nodes along the Highway 101 corridor from the Golden Gate to Healdsburg. Different technology, same goal: resilient regional comms. Visit North Bay Area Mesh.
