The growing power of science and technology has brought many conveniences to people's lives. The emergence of mobile phones has completely changed people's previous ways of communication. Nowadays, the functions of mobile phones are becoming more and more powerful, which also leads to people's reluctance to leave mobile phones for a moment, and even feel that they lack mobile phones, which makes people more prone to anxiety. While you can't live without mobile phones in your daily work and life, don't forget that using mobile phones in some places is inappropriate and even illegal. For example, using mobile phones in theatres is very inappropriate, and using mobile phones in confidential places will be suspected of violating the law. Therefore, in some places where mobile phones cannot be used, it is particularly important to use mobile phone signal jammer. For example, in order to prevent candidates from cheating, mobile signal jammers are usually installed in the examination room, which also shows that the examination is fair to every candidate.

We all know that the mobile signal scrambler will interfere with wireless signals, but its working principle is not well understood by many people. Let's popularize it here.
During the working process, the mobile phone signal jammer scans from the low frequency band of the forward channel to the high frequency at a certain rate, and transmits white noise interference signals to interfere with the signal of the mobile phone receiving messages, so that the receiver cannot normally detect the data connection sent by the signal source, so it cannot establish a connection with the signal source, and the receiver presents a state of no signal, limited service, etc.
