The use of computers, mobile phones, and other communication electronic devices through network servers inevitably leads to the leakage of confidential information, and the emergence of some interference devices is mainly used to prevent the installation of such devices in school examination halls to prevent cheating, and so on. Of course, the emergence of frequency jammers is not only due to these reasons, but also lays the groundwork for the development of high-tech. Currently, there are many places where jamming devices can be used, and the application range of frequency jammers is quite extensive.

In normal operation, the communication signal of the jammer is continuously scanned from the low frequency band to the high frequency band of the forward channel (from the base station to the mobile phone), thereby interfering with the normal signal received by the mobile phone, presenting a state of no signal or no service, making it unable to communicate. In fact, the jammer product is not truly interfering with mobile phone signals, but rather emitting a large amount of interference signals to cover the signals used by the phone, thereby achieving the purpose of interference.
In daily life, frequency jammers are established to interfere with the operation of communication equipment. This device cannot affect the application of mobile phones based on the data signals received by the communication base station, and can only be adjusted for mobile phones. If you want to stop mobile communication and internet access, you only need to install products such as these interference devices, and the phone will not be able to accept special phone calls and information content within the range, achieving the desired purpose.
