As for some signal jamming equipment, it can directly shield the signals of various electronic communication equipment in the market. At present, it has been applied in many places. The most widely used place is that it can often be seen in school examinations, prisons, detention houses and meetings. 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, you can't use mobile phones, so use the wireless jammer dedicated to the school examination at these times  It is very necessary. The radio jammer    What principle is used to interfere with mobile phone signals?

Before that, let's 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 a certain frequency modulation state of the mobile phone. For the above, wireless jammer    In operation, a certain speed is used in the forward channel to scan from the low-frequency band to the high-frequency band. Thus, it interferes with the normal use of the mobile phone and causes the signals received by the mobile phone within the working range of the signal interference equipment to form garbled codes. The mobile phone cannot receive the normal data signals transmitted from the base station, so it can not continue to be used.
