Can schools jam cell phone signals

Hello June

It is true that many schools are now using such devices. The main reason is that more and more students cheat on their smartphones. At the same time, students who use mobile phones for a long time are likely to become short-sighted. So the French education ministry has a new policy. Middle school students are prohibited from carrying mobile phones to school.Many countries, such as Japan and China, use jamming devices directly. Recently, the United States began to use the device. Therefore, the school has the right to do so.
