With the development of science and technology and the progress of society, mobile phones have become a must-have for the public. Parents rely on mobile phones to communicate with their children, and many courses also require electronic devices. However, this caused a lot of inconvenience to the high school entrance examination. In order to ensure the fairness and justice of the examination, the school will install topsignaljammer signal jammers in each classroom to prevent candidates from cheating and provide a good examination environment. So how does the topsignaljammer cell phone jammer work? Let me reveal to you.

The cell phone jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. The scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as searching the network, no signal on the mobile phone, no service system, etc. Is it very simple? The principle is very simple, but now the network communication is very developed and progressive. 5G mobile phone signals are already fully ubiquitous. Therefore, the technicians of topsignaljammer mobile phone signal jammer have achieved these needs through unremitting efforts, cooperating with production personnel, quality inspection personnel, and after-sales feedback to provide you with more effective products,
