When the cell phone signal jammer<\/a> is working, it will scan from low frequency to high frequency of the forward channel (the channel from the signal tower to the mobile phone) at a certain speed. This scanning process will interfere with the mobile phone’s ability to receive information signals, causing the mobile phone to fail to detect the base station’s signal and unable to establish a connection, thus being in a state of no signal and no service.<\/p>\n\n\n\n

At present, the mobile phone signal jammers used in the examination room cover all frequency bands, thus affecting the 2G\/3G\/4G\/5G frequency bands of the three operators. In addition, these jammers<\/a> can also block all Wi-Fi and Bluetooth signals.<\/p>\n\n\n\n
