What Is A Drone Signal Jammer?

UAV (Unmanned Aerial Vehicle) jammers are devices that operate at the same frequency as quadcopters and jam data transmission. However, the matter is not limited to this; they can completely disable the control of the flying device, causing it to either land on the ground or be carried away by the wind in an unknown direction.

A drone jammer is not a pair of pajamas that you put on before going to bed. It’s also not as vicious as the name suggests – it won’t freeze your drone’s propellers mid-flight and make it drop to the ground (legally, of course).

A UAV jammer, or simply a jammer, is a machine that emits electromagnetic noise at radio frequencies with the purpose of superimposing the same radio and GPS signals that your drone uses to operate. The frequency of a drone jammer is generally fixed at 2.4GHz or 5.8GHz, which are public frequencies not allocated to manned aircraft, public broadcasting, or cellphone signals.

Drone jammers often resemble guns and work by projecting the jamming signal in a cone-shaped pattern of about 15-30 degrees. When a drone is hit with the jammer’s signal, the most common reaction is for the drone to return to its starting point (unless the GPS is also jammed), giving the jammer a chance to track the drone back to the pilot. In some cases, a UAV jammer may cause the drone to land in place or crash, allowing for a forensic investigation.

The high-performance drone jammers available on the market can operate from a distance of up to several kilometers and become more effective the farther away the pilot’s remote controller is from the drone. This technology is an asset to both pilots and control authorities, as it poses far less risk than other anti-drone measures and allows the pilot’s drone to remain unharmed in most situations.
