There are many ways for mobile phones to obtain information, such as the most common Internet, and then SMS calls. Even Bluetooth can transmit information within a certain range, and the radio can also receive information from a certain station within a certain frequency to obtain information. There are many ways, but they are all transmitted by a fixed-length wave, and the wave of the mobile phone is linked with it, and the information is obtained.
Then the wave is invisible and intangible. If someone does not want the mobile phone to receive the message, it is to block or disturb the regular wave. The signal jammer is capable of this. When the mobile phone is working, the wavelength of the mobile phone is connected with the radio waves of the base station, but within a certain frequency range, a certain wave frequency is used for data and sound transmission. If there is no radio wave of the base station, there is no way for mobile phones. normal operation.
According to the mobile phone communication principle, the mobile phone jammer scans around at a certain speed during work, and the scanned low-port device will be interfered with by another specific wavelength, which disturbs the wavelength of the message received by the mobile phone to form garbled interference, The mobile phone cannot normally detect the data sent by the base station so that the wave of the mobile phone cannot be connected with the wave of the base station, and the information cannot be transmitted. The mobile phone will display phenomena such as searching the network, no signal, and no service system.
The signal interference of the mobile phone is divided into man-made and natural. Man-made interference is the signal shielding device, and natural interference in the environment, and the problem of the hardware facilities of the mobile phone.
