Drone jammers of some frequency range have become so popular with the popularity of various radio transmitting devices. Anti-drones are certainly a cutting edge piece of equipment in the development of electronic equipment.
Not always used for peaceful purposes, drones can be installed for surveillance, unauthorized photography, espionage or transport of weapons and drugs. Using drone banks, fraudsters can obtain personal information about the person and even access bank account numbers, safe deposit box passwords and other information. The size of the installation is small, so many people will not recognize the real danger, but can treat the drone as a bird.
A drone signal jammer is designed to disrupt a drone by emitting electromagnetic noise at the radio frequency at which the drone operates and transmits video, and at a power level sufficient to drown out any effective communication between the drone and its pilot. Typically, these are 2.4Ghz or 5.8Ghz ("RF jamming"), which are "unassigned" public frequencies, meaning that the drone jammer will not interfere with manned aircraft, cell phones, public broadcasting, or other dedicated radio bands.
Why are drone jammers safer than other countermeasures?
Drone frequency jammers are effective against drones and do not damage them or evidence. Other options typically result in damage or destruction of the drone, which can destroy evidence and lead to private property damage costs.
Another consideration is whether the drone is carrying a bomb or other dangerous item. The use of jammers is probably the safest approach, as jammers usually cause the drone to return to its point of origin. This is much safer than shooting down a bomb-laden drone, which could result in a bomb explosion, injury or even death.
