At present, there are two forms of jamming mobile phone data signals:
1. One way is the same as the principle of Internet TV. Put the mobile phone into the packaging bag of wire mesh products, and each electromagnetic wave will be shielded normally.
2. Another reason is that when we enter a range, there is no signal on the mobile phone.
In fact, the manufacturer of the wireless signal jammer tells you how the shielding works - the wireless signal jammer has the same electromagnetic wave transmission system as the automatic mobile phone in this area. The signal it releases will damage the signal in the phone. At present, the wireless signal jammer equipment works according to the second method in the sales market. In fact, the basic principle is so simple, but it is illegal to use this frequency band without permission, which is not easy to cause economic benefits, but schools have gradually used it to prevent it.
Working principle of wireless signal jammer: What is the specific principle of harming the decline of mobile phone data signal? When the mobile phone is working, the mobile phone and the base station should be connected within a certain frequency range according to the radio wave, and complete the transmission of information and sound effects through a certain baud rate and modulation. According to this communication principle, under the premise of working, the wireless signal jammer of data information in the mobile phone should output power at a certain speed to export the high-end scanner of the channel. The scanning speed will damage the data signals of the protocol type received by the mobile phone. The mobile phone cannot detect the traditional data information transmitted by the base station, making it unable to establish a connection with the base station. Mobile phones are specifically shown as website search, poor signal, no service system, etc.
Within a certain frequency range, the mobile phone and the base station can transmit information and sound efficiency through a certain baud rate and modulation according to the radio wave connection. During operation, the wireless signal jammer shall scan to the high end according to the low power of the trend wireless channel. The scanning speed will damage the error code in the data signal of the mobile phone receiving protocol type. The mobile phone cannot detect the traditional data information transmitted by the base station, making it impossible for the mobile phone to establish contact with the base station, so as to ensure the purpose of shielding the mobile phone data signal.
