Signal Jammer can interfere with the signals of various electronic communication equipment. At present, it has been used in many places. The most widely used place is that it can often be seen in school exams. After the changes of the times, today's information dissemination speed is very fast. With a mobile phone, through some communication software and networks, the information sent in the blink of an eye can be spread to all corners of the world. For some environments such as the examination room, mobile phones can not be used, so it is very necessary to use signal jammers at some times. How do jammers interfere with mobile phone signals?

Before that, we should first understand the principle of communication equipment. Within a certain working range, the base station completes the transmission of information through wireless signal technology and the state of frequency modulation of the mobile phone. For the above contents, the Signal Jammer scans from the low frequency band to the high frequency band at a certain speed in the forward channel during operation, so as to interfere with the normal use of the mobile phone. In this way, the signals received by the mobile phone within the working range of the Signal Jammer form garbled code, and the mobile phone cannot receive the normal data signal transmitted from the base station. Naturally, the mobile phone can no longer establish contact with the base station. At this time, some functions of the mobile phone on the Internet can not be used. The main performance is that there is no signal in the search element and no service in the system, so as to achieve the desired effect.
