Mobile phone has become an indispensable tool and has the functions of transmitting information, video and recording, so it is likely to lead to the leakage of important information of some institutions. Many departments have taken measures to install wireless jammers to safeguard their own interests. Well, in places where information must be kept strictly confidential, such as government organs, banks, examination halls, and so on. In some important examinations, basically every school will install signal jammers to prevent candidates from cheating. During the final and college entrance examinations, as long as the mobile phone enters the interference area, it will not receive the signal or the signal is very weak. In addition to these places, wireless jammers should also be used in gas stations, because gasoline is easy to volatilize, and the air in gas stations will be mixed with many gasoline molecules, so the sparks generated by open flames or other substances will cause explosions. The mobile phones we use have this safety hazard when making calls or sending messages, which may lead to fire in gas stations.

The wireless jammer can generate specific electromagnetic signals, which limits the use of mobile phones in the specified interference area. By installing such equipment, we can avoid the interference of mobile phone noise, prevent those leaks and criminal incidents, and more importantly, play a major role in maintaining social order and protecting people's lives and property.
