Jammer-MartOctober 2022
After the wifi jammer is installed in the toilet of the office building, the 4G network can be blocked. At present, the wifi signal jammer is in the full frequency band. All Bluetooth signals are blocked. Therefore, if you move into the toilet, and all the cards of China Unicom have no signal and cannot make calls, it may be that a wifi blocker is installed.
