Use of signal jammers in police activities

Use of signal jammers in police activities

  • 2022-10-09

The signal jammer is a widely equipped explosion-proof equipment in places related to explosion elimination. Signal jammers are usually used to conduct defensive jamming against remotely controlled explosive objects, and can play a role in many important police activities. With the full popularity of 4G networks, the data traffic charges of major operators have been reduced, and various real-time video communication software and video live broadcast platforms have risen rapidly. Although these softwares bring convenience and entertainment to people's lives, they also interfere with the law enforcement activities of the public security organs to varying degrees. The signal jammer shields and covers the radio signal by transmitting high-power multi band radio waves. It is usually used to conduct frequency interference on the remote explosive device at the explosion site, so that the explosive device cannot be detonated.

There is no trivial matter in the explosion case. The public security organs are equipped with signal jammers to prevent the threat of remotely controlled explosives. The application of signal jammer in dealing with explosion related cases is relatively mature. Turning on the signal jammer at the blasting site has become one of the primary means for some explosive disposal teams.

When dealing with the explosion site, the full frequency band shall be used as far as possible to block interference, and the point-to-point remote control low-frequency signal shall be completely covered with the high-frequency signal of 5G mobile phone. The number of RF channels and RF power required by this interference mode are very large, so high requirements are put forward for equipment performance. The upgrading and daily maintenance of signal jammer equipment in the later stage should be strengthened.
