How can schools comfort mobile phone use? Recently, a responsible teacher in Philadelphia tried to explain to her parents that her school had just taken the phone from her son and the children would stop using the phone within a few weeks. Parents are not impressed. We can see that most people support teachers who use signal jammer. The jammer can help them block most types of signals, prevent students from cheating, and use cell phones in the classroom. Therefore, the proper use of jammers is not a bad thing.
