Can the student party still go online after the school uses the mobile phone signal jammer?

Nowadays, many schools have installed mobile phone jammers. After the shielding is turned on, can the student party still be able to access the Internet? Let’s find out with the editor of the mobile phone signal jammer manufacturer:

Generally speaking, there are three ways to surf the Internet on a mobile phone.

One way is to surf the Internet via the mobile phone operator's signal. As soon as the shielding device is turned on, the mobile phone cannot receive the operator's signal, which leads to the inability to make calls or text messages, so the Internet cannot be accessed naturally, and the shielding is effective.

In two ways, the mobile phone is connected to WIFI to surf the Internet. If you are lucky enough, the blocker does not carry the function of blocking the 2.4gwifi channel, then congratulations, although you can’t call and text messages, but I have a network in the world, QQ and WeChat voice and video can still be carried out, and it’s no problem to watch movies and play games. However, if the shielding device supports the wifi shielding function, then the Internet cannot be accessed in this case, and the shielding is effective.

There are three ways, the LAN port of the wired network is directly connected to the mobile phone. This method is like entering the world of no one, just like a computer directly connected to a network cable, no matter whether the shield is opened or not, there is no interference at all, and the network speed is smooth. But if there is no LAN interface on the external network, it will be called not every day, and it will not work.
