The installation of cell phone jammer in the test center is the first time in the history of the county's college entrance examination. In the past, individual schools could only deal with high-tech cheating tools by purchasing signal detectors such as "Cheating gram", but the effect was not ideal. The unified configuration of Cigarette Outlet Cell Phone Blocker is mainly to drown the communication signals of ordinary mobile phones and base stations in noise by transmitting noise waves on the same channel.
In this way, no matter whether candidates carry high-tech cheating tools such as PHS or mobile phones, they cannot receive signals normally within the shielded coverage area, which can effectively prevent cheating by using high-tech communication tools. Now that the functions of mobile phones are getting more and more powerful, sometimes you feel that the computer is useless, but it can actually block the signal of the mobile phone. If blocked, it has no effect. Some people will be a little worried, that is, the performance of the mobile phone is so strong, can the Cigarette Outlet Cell Phone Blocker mobile phone signal be blocked? The power of some signal jammers is relatively small, the shielding signal range is also small, and the low-power mobile phone jammers have poor ability to penetrate walls.
