When the mobile phone communicates with the base station, Cell Phone Tracker Blocker Iphone is like a troublemaker, deliberately making noise around you. The noise signal is so large that the mobile phone can't understand what the base station is saying, and the base station can't hear what the mobile phone is saying. In fact, this is not to shield the mobile phone signal, but to obliterate the signal sent by the mobile phone in a large number of noise signals, so as to achieve the purpose of interference. At present, the mobile phone signal jammers used in the examination room are all full frequency bands, which can interfere with all the frequency bands of the three operators 2G/3G/4G/5G, and WIFI signals and Bluetooth signals can also be shielded. cell phone jammer

The principle of mobile phone signal jammer. However, the frequency range of electromagnetic waves ranges from several Hz to several hundreds of GHz, and each segment may be used as a communication signal. Will there be some special frequency bands that are used in the examination room? Indeed, radio communication tools with dedicated frequency bands "came into being" in this context. The working frequency band of these devices is selected outside the frequency band covered by the mobile phone jammer, Cell Phone Tracker Blocker Iphone has no effect on them. For this special radio communication tool, the examination room is specially equipped with a monitoring vehicle equipped with a radio monitor for real-time monitoring of radio wave signals from unknown sources.
