Unmanned Aircraft Systems (UAS) are becoming increasingly popular in the military sector, and to ensure their safe operation, they rely on specific frequency bands for remote control and telemetry. The most commonly used frequency bands for military UAVs are between 840.5 MHz and 845 MHz for remote control uplink, and 841-845 MHz for telemetry downlink. In addition, drones with remote control typically use the 900 MHz frequency, while those with camera transmitters usually use the 2.4 GHz frequency. However, some of the most recent drones have shifted to the 5.8 GHz frequency to avoid interference from wireless transmissions. The use of different frequency bands is essential for the safe operation of UAVs.
By using the right frequencies, military personnel can ensure that their drones are able to communicate with their remote control systems without interference from other wireless signals. It is important to note that different countries have different regulations regarding the use of UAVs and their associated frequencies. Therefore, it is important to check with local authorities before operating a drone in a particular area.
