# Sub-GHz
The Flipper Zero "Sub-GHz" radio is used for receiving and transmitting frequencies below the 1GHz (1000MHz) range.  In particular, the firmware supports 300-348 MHz, 387-464 MHz, and 779-928 MHz operational bands.  Depending on your region there may be additional [restrictions](https://docs.flipperzero.one/sub-ghz/frequencies).
