The wifi jammer device in our school, even if I put my mobile phone next to the shielding device, it cannot block Unicom 3g. Other mobile numbers are blocked. I have not heard of telecommunications. A better shielding device should do full-screen segment shielding. , the school is only used to pretending slightly.

Now the standard wifi jammer on the market can block all 2G/3G/4G mobile phone signals and 2.4G WIFI signals, so 4G can definitely be blocked. Unless there are 4G signal amplifiers of the three major operators in the place of use, the 4G signal in the environment is particularly strong, and the power of the wifi signal jammer is relatively small and cannot be suppressed. At this time, 4G shielding is not good or not shielded. Happening. 4G can definitely be blocked under a normal signal environment.
