I am a teacher and I've seen a lot of students using WIFI to access Youtube and Facebook in class recently. I don't think it's a good phenomenon. I learned that there's a device called a WIFI jammer. I want to know that it can be used in school?
Currently, it is legal for education institutions in most countries to use WIFI signal jammer. If you want to stop students from getting distracted in class. It is recommended that you use jamming devices that can block WIFI and 4G signals
