Which Frequency Bands Are Used by Commercial and FPV Drones?

Learn common commercial and FPV drone frequency categories, Remote ID, cellular links and how to specify RF detection coverage with a site survey.

A buyer-focused guide to common commercial and FPV drone link categories, Remote ID, cellular connections and why a spectrum survey matters. Commercial and FPV drones do not use one universal frequency. Many consumer systems use unlicensed 2.4 GHz or 5 GHz spectrum for command, telemetry and video, while other platforms use region-specific sub-GHz links, cellular networks, proprietary radios or multiple connections at the same time. **The procurement answer:** define the aircraft and links in your threat model, then verify the local RF environment. A printed list of frequencies is not a substitute for signal analysis, protocol coverage or a site survey. What links can exist on a drone? A single aircraft can contain several radio functions: command and control between pilot and aircraft; telemetry from the aircraft to the controller; analog or digital video transmission; Remote ID broadcast; cellular or other network backhaul; satellite-navigation reception; payload-specific data links. These functions may share one integrated radio or use separate devices. Frequency hopping, adaptive channel selection and proprietary waveforms further complicate simple band-based detection. Common drone frequency categories Frequency category Common legitimate use Detection implication 2.4 GHz unlicensed/ISM spectrum Control, telemetry, digital video, Wi-Fi or Bluetooth-based functions Busy band; protocol recognition and interference rejection matter 5 GHz unlicensed spectrum High-throughput video and control links Propagation and regional channel rules differ from 2.4 GHz Region-specific sub-GHz spectrum Long-range or lower-data-rate control and telemetry Legal channels and permitted power vary by country Cellular networks Networked control, telemetry or payload data Not covered by many conventional drone RF libraries Remote ID broadcast Identification and location data from compliant drones Useful cooperative source, but not complete threat detection GNSS reception Position, navigation and timing Receive-only navigation function, not the same as a pilot-control link The ITU identifies 2.4-2.5 GHz and 5.725-5.875 GHz among internationally recognized ISM bands, but national administrations control how radio services use spectrum. The exact channels and operating requirements must therefore be checked in the destination country. W…
