With the rapid development of science and technology, some interference devices have also emerged, which are mainly used to prevent computers, network servers and communication electronic devices from leaking important information during operation, and to prevent cheating in school examination rooms. Of course, the emergence of wireless jammers is not only because of these reasons, but also to pave the way for the development of high-tech. At present, jamming devices can be used in many places, and the application range of wireless jammers is quite extensive.

During operation, the jammer scans the communication signal from the low frequency band to the high frequency band of the forward channel (the channel from the base station to the mobile phone) at a certain speed, so as to interfere with the normal signal received by the mobile phone, showing no signal and no service status, making it unable to communicate. In fact, the jammer product does not really interfere with the mobile phone signal, but transmits a large number of interference signals to cover the signal used by the mobile phone, so as to achieve the purpose of interference.

In short, the wireless jammer is built to interfere with the work of communication equipment. This device uses the working frequency of the mobile phone, so it cannot affect the mobile phone application according to the data signals received by the communication base station. If you want to stop the mobile phone communication and Internet access, you only need to install these jammers. The mobile phone will stop receiving calls and messages within a special period of time.
