In order to prevent students from excessively surfing the Internet, some universities have begun to use wifi signal jammer
Now the school's signal jammers 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. Therefore, as long as the jammer is turned on in the room, the mobile phone cannot normally make calls, send and receive text messages, and surf the Internet. You want to use WIFI to surf the Internet, unless you use 5.8G frequency WIFI, because 2.4G WIFI has been blocked by the wifi signal jammer. In addition, the only way to use the mobile phone normally is to install a mobile phone signal amplifier near the place where the mobile phone signal blocker is used to compete with it. When the mobile phone signal becomes stronger, the blocker is more difficult to block.
