However, many students use mobile phones, leading to poor grades. Some students secretly use mobile phones in class. If he finds a teacher, he thinks, he will have to stop classes and be careful when that happens. This will reduce the concentration of all students. In addition, students who will not give up even if they are careful are recorded, and a certain number of students cannot participate in extracurricular courses, etc. Therefore, in consideration of this situation, a deterrent device is used. Is an explanation.

Now, with the rapid development of electronic communication methods, the methods are becoming more and more diversified. Cheating seems to happen at the same time as the examination system. Students want to get good grades, so they cheat. There is a case of posting entrance exam questions found in a university. I don’t know how I posted it during the exam, but by the way, I tried to enter actual questions into my mobile email, but it was a lot of work. Every university is prepared to submit damage reports and complaints. On the other hand, we have taken measures such as prohibiting the use of mobile phones, considering the use of metal detectors, and checking the names of people who go to the toilet.

Many people study in places such as buses and subways. But some people play mobile games. Make a loud sound. This makes people who read books feel uncomfortable. Violations of etiquette are common in public places such as libraries, movie theaters, and hospitals. For example, in a movie theater, if a mobile phone rings during a performance, it may interfere with the audience watching the movie, cause discomfort or hinder the performance of the performance. Request to turn off the power of mobile phones in the lobby. However, there may also be bystanders deliberately failing to comply with this, or forgetting to turn off the phone without malicious intent. It is difficult to prevent the bell from ringing on all the mobile phones in the lobby. If the interference wave of the frequency used by the mobile phone can be emitted, it will interfere with the communication of the mobile phone, so it is sure to prevent all the mobile phone bells in the hall from ringing. For the same reason, similar effects can be expected in hospitals where patients need to rest quietly.
