At present, in terms of security, very few criminals, terrorists and spy organizations, in order to endanger society and obtain confidential information, try to create vicious explosions and obtain important information by placing remote controlled explosives, remote monitoring and other means in public places and confidential meeting places. Therefore, electronic jammers are widely used at explosion disposal sites, confidential meeting places and other places to ensure the safety of people's lives and information. The electronic jammer is specifically used in these aspects:

① Protection of bomb disposal force: before bomb disposal, the wireless signals around the bomb can be effectively shielded to ensure that terrorists cannot detonate bombs during bomb disposal to avoid losses;

② When carrying out the arrest task, the police can use electronic jammers to shield the on-site signals, so as to prevent the bandits or the undercover officers of the police force from leaking secrets through wireless devices, and ensure the smooth execution of the arrest task;

③ It can be used to prevent terrorists from detonating wireless detonating bombs placed in military protected areas, government agencies and other important places; At the same time, the electronic jammer can effectively prevent terrorists lurking near the army from using wireless communication equipment to communicate with the outside world;

④ For some emergencies, electronic jammers can be installed in some fixed places to provide safety protection.

To sum up, with the development of radio technology, the application scenarios of electronic jammers, which used to be used as protective equipment for explosive disposal sites, are becoming more and more extensive.
