Use wireless wifi to surf the Internet. In this case, it depends on whether the mobile phone signal shielding device installed by the school has the function of shielding the 2.4gwifi channel. Block students from using wifi. However, if the signal shielding device carries the function of shielding the 2.4gwifi channel, all signals will be completely shielded, and the students’ mobile phones may be connected to the Internet, and the shielding is effective.
Use the base stations of major operators Mobile, Telecom, China Unicom, etc. to send signals to access the Internet. To add to this problem, our mobile phone signal shielding device is installed. After the mobile phone signal shielding device is turned on, the mobile phone will not be able to receive the signal sent by the operator’s base station. At this time, the student’s mobile phone will not be able to receive calls, send text messages, and surf the Internet. Effectively Prevent students from playing with mobile phones in class.
Use the wired network LAN interface to link the mobile phone to the Internet. If students use this method to surf the Internet, no matter what means they use, it will be useless, and no matter how powerful the mobile phone blocker will be. But if you don’t use the wired LAN interface to access the Internet, no matter what the network will be blocked. In any case, as a student, my main task is to read books well, actively study hard, and become the hope of the motherland’s future. I can’t just spend a day on the Internet and playing with my mobile phone.
