Nowadays, mobile phone communication technology is becoming more and more advanced. There are only two ways to affect the transmission signal of mobile phones:
1. The first method is the same as the basic operation of TV. Put the mobile phone in the product packaging bag made of wire mesh, and generally every radio wave can be blocked.
2. Another main reason is that when we enter a range, there is no signal on the mobile phone.
In fact, the cell phone signal blocker manufacturer tells you the working state of the blockage-the mobile phone signal blocker has the same radio wave transmitter as the fully automatic mobile phone. The data signal it releases will destroy the signal in the mobile phone. At present, the mobile phone signal blocker works in the equipment market in the second way. In fact, the basic concept is so simple, but it is illegal to use this frequency band without permission, and it is not easy to cause economic benefits, but now schools have gradually used these to prevent it.
Mobile phone signal blocker working mode acceptance: blocking the mobile phone to send the signal to reduce the specific principle? When the mobile phone is working, the mobile phone and the base station should be connected naturally in a certain working frequency band according to electromagnetic waves, and transmit information and sound effects through a certain serial port baud rate and allocation. According to this communication principle, under the premise of operation, the data signal blocker in the mobile phone should be powered at a certain speed to extract high-quality scanning signals from the wireless channel. Scanning speed will destroy the data signal of the mobile phone receiving protocol type, and the mobile phone cannot detect the traditional data transmitted by the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone mainly manifests itself as web search, poor signal, mobile phone no service and other systems.
Within a certain working frequency band, the mobile phone and the base station are connected by electromagnetic waves, and the information and sound are efficiently transmitted according to a certain serial port baud rate and configuration. During operation, the mobile phone signal blocker should be adjusted from the low-power scanning channel to the high-end. Scanning speed will destroy the error code in the data signal of the mobile phone receiving protocol type, and the mobile phone cannot detect the traditional data transmitted by the base station, so that the mobile phone cannot establish a connection with the base station, so as to ensure the effect of shielding the mobile phone data signal.
