As the use of mobile phones becomes more and more popular, the smart functions of mobile phones continue to expand. In addition to basic call and SMS functions, they also have more application functions such as digital cameras, camcorders, voice recorders, and Internet access. These smart phone applications have greatly facilitated communication between people, facilitated the transmission of information, and enriched people’s lives. However, while mobile phones are actively promoting social development, there are many problems caused by the proliferation of mobile phones. The disadvantages that come, such as in the production workshops or assembly lines of some large factories and enterprises: It is necessary to restrict the use of mobile phones in some special places, such as factory workshops, and traditionally rely on enumerating rules and regulations, personnel supervision, and punishment systems. Thoroughly eradicate and eliminate the proliferation of mobile phones.
At present, the more feasible method from the perspective of technical products is to install mobile phone signal jammers at appropriate locations in the factory area. Each mobile phone signal jammer can cover a certain area, and these coverage areas can be formed into an area in the form of a cellular network. The coverage to achieve complete signal shielding in large areas. The current mobile phone signal jammers are all full-band. 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.
The working principle of the signal jammer: In a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method. The jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. The scanning speed can cause garbled interference in the message signal received by the mobile phone. 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 and achieve the purpose of shielding the mobile phone signal. No service system and other phenomena.
Eavesdropping, leaks, cheating in examination rooms, medical accidents, and gas station explosions have emerged one after another, accelerating the promotion and use of mobile phone signal jammers. Signal jammers are mainly used in examination rooms, prisons, factories, gas stations, mobile phone bomb prevention, oil depots, liquefied gas stations, detention centers, interrogation rooms, courts, labor reform teams, conference rooms, theaters, churches, libraries, school dormitories, In special security and confidential occasions (confidential offices, negotiation rooms, mobile vehicles, mobile politicians and business dignitaries guarding) scenes, etc., the status of mobile phone signal jammers in social life is becoming more and more important.
