Mobile cell phone jammer have become standard equipment in the exam room. Not only high school entrance examinations, but also postgraduate exams, civil service exams, and various qualification certificate exams, mobile phone jammers are needed to prevent candidates from communicating with the outside world through wireless signals. The current mobile phone signal jammers are all full frequency bands. It can shield all the 2G 3G 4G signals, 2.4G WIFI signals and Bluetooth signals under all the three operators of China Mobile, China Unicom and Telecom. Its principle is sent by itself. The frequency interferes with the mobile phone receiving the frequency sent by the base station and the wireless router, so as to achieve the purpose of shielding them.
We can compare a mobile phone to a radio for the time being. The radio often churns or the channel is simply disorganized and cannot be heard. This is the signal is disturbed.

For the uplink and downlink channels of the mobile phone system, it uses techniques such as frequency multiplication, frequency division, and frequency hopping filtering to analyze the required shielding frequency; customize a spherical shielding space according to the power of the shielding device, and automatically form a shielding magnetic field within a specified range. Make mobile phones (including PHS-PHS GSM-China Unicom, China Mobile, CDMA-China Telecom) mobile phones in this space invalid. When the shielding device is in working condition, it can disable the function of sending and receiving signals of the mobile phone within the specified range, and cannot dial out and dial in, so as to achieve the purpose of compulsory prohibition.
