With the improvement of people’s living standards, mobile phones seem to have become their main tools. They not only use mobile phones, but also use them as social and entertainment devices in their leisure time. They use mobile phones not only at home but also at school, which seriously affects their studies and teachers’ courses. We know that many schools are banning students from using mobile phones, on the one hand, for students’ learning, on the other hand, for better management of the school, and the school is in a normal system. But the student rebellion did not take the school’s ban seriously. Although it said that the school found that students were severely punished for using mobile phones, it did not stop the phenomenon. Then, the school adopted a more effective method, that is, using cell phone jammer to block cell phone signals from the school.
