In the era of advanced smart technology, various high-tech technical tools are constantly appearing, which brings us great convenience, such as smart phones, smart watch TVs, drones, etc. Different communication systems use different frequencies, so Everyone has nothing to worry about and does not interfere with each other. Once the frequency is disturbed or intercepted, these high-tech devices become a pile of scrap iron. The cell phone jammer is designed to prevent the abnormal use of the mobile phone, and the signal scramblers device specially designed to shield the cell network is successfully developed.
The working principle of the mobile phone jammer is to transmit the same frequency band signal as the mobile phone. Because the frequency is the same, the mobile phone cannot distinguish which signal is a conventional base station signal, thereby achieving "interference", and the mobile phone cannot work normally. As long as there is a cell scrambler with the same frequency as the phone, when the base station tries to connect to the phone, it will emit a lot of "noise". The phone is not recognized by the normal signal, which makes the phone can not work. Today's cell signal jammers not only block 2G bands, but complex network scramblers can block multiple types of networks at the same time, such as 2-3-4-5G and GPS WiFi signals.
