As we all know, the smart jammer consists of many interference modules with different frequencies, and these interference modules correspond to the frequencies of the antenna one-to-one, so why do they correspond to one-to-one? If not, what are the problems. The interference module of smart jammer is divided according to the signal frequency used by mobile phone. The frequency ranges from 800M to ...

According to the style selection of mobile phone signal jammer, portable shield can be divided into built-in antenna and external antenna according to the style. The advantage of choosing a built-in antenna is that if the portable jammer is fixed in the test room, the built-in antenna is better than the external antenna. The external antenna is bare. It is easy to unscrew the antenna and cut off t...

Whether smart jammer can cause damage to mobile phones is a question that many shielded people have. Smart jammer transmits interference signals with the same frequency as the mobile phone receives, but it only blocks the connection between the mobile phone and the base station, so that the mobile phone is always in a signal-free or search state, which will not harm the mobile phone itself! When t...
