Jammers work by blasting electromagnetic noise at the radio frequencies that drones use to operate and emit information. Short of shooting down a drone with physical projectiles, the only anti-drone technology in existence is what is commonly known as a “drone jammer.” Effectively, they drown out the conversation between a drone and its operator. This is usually either 2.4Ghz or 5.8Ghz– that a drone uses to communicate with its ground station. This prevents jammers from interfering with manned aircraft, cell phones, public broadcasts, or other dedicated radio bands.
The drone jammer does this by sending its own electromagnetic signal at the same frequency, thus overriding the drone’s communication systems. In most cases, this will result in the drone activating its Return to Home function, through which the drone pilot can be identified.
Jammers can either be stationary, mounted devices, or built into highly mobile, gun-like devices to allow someone to land the drone on the ground safely.
