Can mobile jammers block three operators?

The mobile phone jammers on the market are all full-band, which can shield all the 2G 3G 4G signals, 2.4G WIFI signals and Bluetooth signals under all 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 to completely shield the mobile phone signal jammer. If you want a mobile phone to work normally, unless the mobile phone signal is very strong, if it is a mobile signal amplifier, it is difficult to shield the mobile signal.

The mobile cell phone jammer used in the examination room is full-band, which can shield all the 2G 3G 4G mobile phone signals and 2.4G WIFI signals of China Mobile, China Unicom and China Telecom. So as long as the mobile phone jammer is placed in the classroom, all mobile phones will not be able to make calls. , Send and receive text messages and surf the Internet. The statement that mobile phone jammers do not shield China Telecom and China Unicom is absolutely incorrect. Unless there are telecom and China Unicom signal transmission towers near the place of use, the signals of Telecom and China Unicom mobile phones are particularly strong, and the power of the mobile phone signal jammer is too small and not suppressed. At this time, Telecom and Unicom may not be able to shield. Happening.

For example, when the mobile phone jammer is turned on in my school examination room, I can only use telecom mobile phones, because there is a telecom transmission tower on the mountain opposite to our school, and China Mobile Unicom is very far apart, and the mobile phone will have a signal against the wall. This is also wrong. , But the farther away from the mobile phone signal jammer, especially at the window, there may be signal leakage.
