The mobile phone jammer can interfere with the signals of various electronic communication equipment, and has been used in many places. And the most widely used place is in the school examination, we can often see its presence and absence. With the changes of the times, the speed of information transmission is very fast. With a mobile phone, through some communication software and networks, the information sent can be spread to all corners of the world in the blink of an eye. Mobile phones cannot be used in such environments as examination halls, so it is very necessary to use mobile phone jammers in some cases. How does the mobile phone jammer interfere with the mobile phone signal?

Before that, we should first understand the principle of communication equipment. Within a certain working range, the base station transmits information through wireless signal technology and frequency modulation of mobile phones. For the above contents, the mobile phone jammer will use a certain speed to scan from the low frequency band to the high frequency band in the forward channel, thus interfering with the normal use of the mobile phone. In this way, the signals received by the mobile phone within its working range will become chaotic, and the mobile phone will not be able to receive the normal data signals transmitted from the base station, so the mobile phone will not be able to establish contact with the base station. At this time, some functions of the mobile phone related to Internet access can not be used, mainly showing that there is no signal in search and no service in the system, which achieves the desired effect.
