The intelligent jammer shields and covers the radio signal by transmitting high-power multi band radio waves. It is usually used to interfere with the frequency of the remote-controlled explosive device at the explosive disposal site, so that the explosive device cannot be detonated. At present, the rapid development of wireless network has brought great convenience to people's life, but also brought many new challenges to the disposal of major police cases. The most essential purpose of public security organs equipped with intelligent jammers is to prevent the threat of remote-controlled explosive devices.

When dealing with explosion related sites, the police should try to use full band blocking interference to fully cover low-frequency signals from point-to-point remote control to high-frequency signals of 4G mobile phones. This interference method requires a large number of RF channels and RF power, so it requires high equipment performance. It is aimed at the possible remote-control explosive devices nearby, as well as the interference to communication signals and GPS signals. Interference with GPS signals can prevent the location and trajectory of motorcade and personnel from leaking, and illegal personnel from using drones to attack.

The intelligent jammer cuts off the suspect's communication, which can prevent him from knowing the deployment of the police through communication tools, and avoid him from contacting his partners outside. The control of radio is mainly the control of mobile phone communication signals. Only one intelligent jammer can effectively control field communication.
