Using drone jammers to restrain "black flying" drones
In recent years, the drone industry has developed rapidly, and drones have gradually entered the public's field of vision. When some ordinary people came into contact with drones, they did not receive professional training to control drones, which also caused a large number of "black flying" phenomenon of drones. For example, once an airport was continuously disturbed by drone activities in just one week, resulting in large-scale flight delays, return flights, or temporary landings at other airports, causing serious losses to airlines and seriously affecting the safety of social and public order. . The use of drone jammer can effectively restrict the "black flight" situation.
The drone jammer transmits high-power interference radio frequency signals by means of signal interference blocking to interfere with the signal connection between the target drone and the operator, so that the drone cannot continue to be controlled, thereby triggering the drone to return to home or landing function. The UAV jammer can continuously transmit electromagnetic wave signals of directional signal frequency to the UAV within the effective range, and cut off the signal transmission between the target UAV and the ground remote controller. This jamming method is not for a single part of the frequency signal, but for all the signals used by the drone. Therefore, as long as it is within the frequency band used by drones, drone jammers can be effective.
Certain devices can interfere with telephone signals and pose as uninterrupted base stations. The problem is that it disables emergency calls. In theory, you can implement some functionality by placing the phone in a place where calls are not allowed (because the operator always knows where the phone is), which puts the phone in "mode". But nobody recommends it as a product or standard, although it is not particularly difficult. It may be because the owner of the cinema or restaurant has to pay.
