Scope of application of mobile phone blocker
Mobile phone signal blockers are generally referred to as blockers, mobile phone blockers, signal blockers, mobile phone signal jammers, mobile phone signal blockers, mobile phone isolators, mobile phone interceptors, etc. There are also functions called mobile communication signal blockers, mobile signal blockers, mobile jammers, signal jammers, mobile blockers, signal blockers, mobile signal isolators, signal isolators, mobile signal truncators, wireless signal blockers, etc.
Within a certain frequency range, mobile phones and base stations are connected through radio waves to transmit data and sound at a certain baud rate and modulation method. The shield scans from the low end frequency of the forward channel to the high end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the phone, and the phone cannot detect normal data sent from the base station, making it unable to establish a connection with the base station. Mobile phones exhibit phenomena such as searching the internet, no signal, and no service system.
The mobile signal blocker is designed for the uplink and downlink channels of the mobile phone system, using techniques such as frequency doubling, frequency division, and frequency hopping filtering to analyze the required shielding frequency. Then customize a spherical shielding space based on the power of the shielding device, which automatically forms a shielding magnetic field within the specified range, and the mobile phone signal within the shielding space becomes invalid. When the mobile phone shield is in working mode, within the shielding range, the phone cannot make or receive calls, send or receive messages, and access the internet normally. At the same time, it will not interfere with the normal operation of other electronic devices. After the phone leaves the shielding range, it can resume normal use, and the machine does not cause any harm to the human body.
The application range of mobile signal blockers is very wide, and they can be used in many occasions or areas, such as various invigilators, prisons, detention centers, drug rehabilitation centers, offices, conference rooms, gas stations, oil depots, churches, hospitals, courts, military areas, libraries, cinemas, factory workshops, and other places.
