Scope of application of mobile phone jammer

Mobile phone signal jammers are generally directly called jammers, mobile phone jammers, signal jammers, mobile phone signal jammers, mobile phone signal blockers, mobile phone isolators, mobile phone cutoff devices, etc. There are also called mobile communication signal jammers, mobile phone signal jammers, mobile phone jammers, signal jammers, mobile phone blockers, signal blockers, mobile phone signal isolators, signal isolators, mobile phone signal cutters, and radio signals based on their functions. Jammer etc.

Within a certain frequency range, mobile phones and base stations are connected through radio waves to complete data and sound transmission at a certain baud rate and modulation method. The jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during operation. This scanning speed can cause garbled interference in the message signals received by the mobile phone. The mobile phone cannot detect normal data sent from the base station, making it impossible for the mobile phone to establish a connection with the base station. Mobile phones show symptoms such as searching the network, no signal, and no service system.

The cell phone blocker uses frequency multiplication, frequency division, frequency hopping filtering and other technologies to analyze the required shielding frequency for the uplink and downlink channels of the mobile phone system. Then a spherical shielding space is customized according to the power of the shielding device, and a shielding magnetic field is automatically formed within the specified range, and the mobile phone signal in the shielding space becomes invalid. When the mobile phone jammer is in working condition, the mobile phone cannot make and receive calls, send and receive messages, and surf the Internet normally within the shielding range. At the same time, it will not interfere with the normal work of other electronic devices. After the mobile phone leaves the shielding range, it can resume normal use, and the machine can There is no harm to the human body.

Mobile phone signal jammers have a wide range of applications and can be used in many occasions or areas, such as various invigilation examination rooms, prisons, detention centers, drug rehabilitation centers, offices, conference rooms, gas stations, oil depots, churches, hospitals, courts, military Important places, libraries, theaters, factory workshops and other places.
