With the rapid development of smart phones, many people have it. It has the same intellectual and functional diversity as an adolescent. They can use their smartphones to play games, watch videos, and browse novels, which are very important to their spare time. They are students after all, and students should focus on their studies and not their phones. So many parents worry about how to get their children to put down the phone and go back to school, which is a common concern. Here I suggest that you can use a wifi jammer to cut off your phone's network so that it doesn't work.
I don't think as a network job we should install wireless wifi signal jammer ourselves. Let's go to a coffee shop and have a cup of coffee to relax and do what we like, and the wifi network is what we must use in the network environment. What's the fun in going to a coffee shop if you use a WiFi jammer? You can also make your own coffee at home. I think cafes, theaters, concert halls should install signal shielding devices, and where should they be installed. The device can provide people with a good rest and work environment. A wireless internet scrambler is installed.

I want to buy my own wifi scrambler, it will interfere with the video signal, the neighbors watching TV is too loud, when I rest, it always bothers me, I am very angry, communicate with them, they don't listen to your advice, I think Should I do something because I can get a device here that can interfere with all kinds of cell phone signals and video interference? I desperately need such equipment to ensure rest.
