Can signal jammers be used in the classroom?
I am an examiner. During the exam, I found that many students are using mobile phones to find answers on the Internet and use mobile phones to cheat. Can I use a signal jammer to block mobile phone communication so that the mobile phone cannot access the Internet?
Hello, if you are trying to prevent students from cheating in the exam room, you can use a signal jammer, because the signal jammer can indeed block the signal communication, so that the mobile phone can't access the Internet, but if people use mobile phones under normal circumstances , then I do not recommend you to use it because you cannot hinder the freedom of communication of others.
