Our school has opened a wifi jammer device, why can my mobile phone (mobile) still be connected to the 4g network?
Jammer-MartOctober 2022
The working principle of the wifi jammer is that the frequency emitted by the jammer, itself interferes with the normal frequency of the mobile phone receiving the router so that the mobile phone cannot be connected to the router it cannot normally make calls, send and receive text messages and surf the Internet. You said that the 4G signal cannot be blocked. There are two possibilities. One is that the wifi signal jammer itself does not have a 4G frequency band, and the other is that the mobile base station may be used to make the signal stronger, and the wifi frequency jammer is difficult to block.
