In order to prevent and eliminate cheating in exams, many schools now generally choose to install mobile phone signal jammers to prevent students from cheating in exams. After the jammer is turned on, can the Student Party still use mobile phones to surf the Internet?

Then let's talk about the three ways of mobile internet access.
The first way is to get online through the network signal provided by the operator. This is a common way to get online. When you go out, you basically use this way to get online on your mobile phone. If you use this way to play games or watch videos, it will consume traffic. If you enter the range covered by the jammer, the mobile phone will not be able to receive the signal provided by the operator normally, resulting in that the network data cannot be obtained by the mobile phone, and you cannot receive and make calls, and you cannot send and receive messages.
The second way is to connect the mobile phone with WIFI. In the coverage of mobile phone signal jammer, if you are lucky enough that the jammer does not carry a device that can interfere with the WIFI channel, then congratulations, although the mobile phone can not receive and make calls and send text messages, but I have a network in hand and can freely surf the Internet. However, if the jammer supports the function of WIFI interference, then in this case, WiFi will also be interfered by the jammer, and the mobile phone will also be unable to access the Internet.
The third way is to connect directly to the mobile phone through the wired LAN port. This method is the same as the direct connection of the computer to the network cable. The transmission of network data through the wire is not affected by the mobile phone signal jammer. This is because the medium of network signal transmission is changed. The jammer can interfere with various wireless signals transmitted through the wireless, and has no effect on the wired data transmission equipment.
