The working principle of the mobile phone is that within a certain frequency range, the mobile phone and the base station are connected by radio waves, and data and sound transmission are completed with a certain baud rate and modulation method.
The principle of the mobile phone jammer is based on the above-mentioned communication principle. The mobile phone jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation.
The scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as a search network, no signal, no service system and other phenomena.
HISEA Electronic Technology Company Limited focus on the development and marketing of security and telecom products.
