License-free under Part 15
In the United States, Meshtastic radios set to the US region operate in the 902–928 MHz industrial, scientific and medical (ISM) band under FCC Part 15 rules. Certified devices used within those rules don’t require a license for the operator, the city or residents. It’s the same framework that covers many wireless sensors and other unlicensed devices.
What that means for a town
- Residents can join without testing or paperwork.
- The city doesn’t need a license to run relays or a hub.
- Encryption is allowed, so staff channels can be private.
When a ham license comes in
Meshtastic has an optional amateur radio mode for licensed operators. It allows operation under amateur rules, which in turn prohibit encryption. Town networks don’t need it, and we don’t use it for public networks.
Other radios that do need licenses
GMRS voice radios need an FCC license (no exam). Amateur (ham) radio needs an exam-based license. See how the options compare.
This is general information, not legal advice. Rules can change; check the FCC’s current Part 15 rules for specifics.
