Drone Jamming Technology
Drone jammers are designed to disrupt the communication between the drone and its controller, by transmitting interfering radio signals, at bands usually used by drones, and at a power level high enough to “drown out” the signals transmitted by the drone.
Commercial drones operate on 2.4Ghz or 5.8Ghz, which are usually used as public frequencies and are not assigned to specific use, such as manned aircrafts, cellular communication, TV & Radio broadcasts, etc.
As such, these bands can be jammed without causing major interferences to the environment. In case the drone relies on stable GPS signal for navigation, the GPS band can be blocked as well, preventing the drone from completing its mission (the drone either crashes or returns to is take-off point).
Drone jammers are typically effective against drones over few kilometers away. The closer the drone is to the jammer, and further from its controller, jamming will be more efficient.
Using EW countermeasures, as a mean to mitigate drones, is the safest way, with the least collateral damage and risk for the “blue forces” (the jammer operator). In the event an armed drone is directed towards a target in risk, the mitigation team can thwart the mission without risking lives and leading to the detonation of the bomb.
