Is the interference range of the police frequency jammer to each frequency band the same?

Is the interference range of the police frequency jammer to each frequency band the same?

Police frequency jammer, also known as police jammer, is mainly used for police handling cases or performing special tasks, such as suspect arrest, sudden group incident handling, communication control, anti-terrorist EOD, low-slow Small drone defense and more.

Police frequency jammers mainly interfere with radio signals, and there are many types of radio signals, and the radio technology and system are different, as well as the difference in the signal strength emitted by the signal transmitter of the radio signal, which will cause the police jammer to interfere. These radio signals, the range of interference will also be different.

At present, the frequency range of civil radio signals is from 20M-6000MHz. According to the different signal frequencies, it can be divided into various uses. Common frequencies such as 20M-100MHz are mainly used for broadcast radios. The advantages are low signal frequency and diffraction distance. far, strong penetration. 100M-500MHz, mainly used for remote control, walkie-talkie communication and so on. 700-5000MHz, mainly used for communication, including the frequency of our common mobile phone 2, 3, 4, 5G, WiFi frequency, GPS navigation and positioning frequency and so on.

The interference range of police frequency jammers to radio signals of different frequencies is also different. In a specific test environment, after testing, the interference range of police jammers to radio radios is 50-200 meters, and the interference range of police jammers to remote control signals is 50-200 meters. The interference range of the mobile phone is about 50-200 meters; the interference range to the mobile phone signal is special, because the mobile phone signal is mainly transmitted by the base station of the operator, and the interference of the police frequency jammer to the mobile phone signal depends on the distance of the base station, different signals Under the intensity, the interference of the police jammer to the mobile phone signal will also be different. The interference distance of the police jammer to the GPS positioning of the drone is generally more than 1500 meters. The interference distance of the drone's digital image transmission is 300-500 meters.

Police frequency jammer have very different interference ranges for different signal frequencies, different signal strengths, and different uses of radio signals.

In general, it can be summed up in one sentence. The size of the interference range of the police jammer is mainly determined by the distance between the signal transmitting end and the signal receiving end, the strength of the signal transmitted by the signal transmitting end, and whether the signal reflection end and the receiving end are determined by obstacles.
