What is the reason why I don't have a signal when everyone else has a signal?

In the final exam, the school turns on the shielding device, the kind that has been a long time. We are all new 4G cards, but mine will be blocked, and my deskmate will be full of letters.
The wifi jammer on the market are full-band, which can block all 2G 3G 4G signals, 2.4G WIFI signals, and Bluetooth signals under the three operators of China Mobile, China Unicom, and China Telecom. You said that the signal at the same table is full. It may be because there are mobile base stations around, so the mobile signal is stronger, and it is difficult for the wifi signal blocker to completely block it. If you want the mobile phone to be used normally, unless the mobile phone signal in the place of use is very strong, if it is a mobile signal amplifier, then the mobile signal is difficult to shield.
