How much scope do schools need to use cell phone jammers?

Mr. MacNeil has taken steps in the past to prevent use, including the purchase of a cell phone jammer, a device that cuts out service. The device is considered illegal, yet no one has been prosecuted in the United States for having one, he said. Mr. MacNeil added that at the time he purchased the jammer, he talked to the teachers in neighboring classrooms about it, who were in full support. The jammer is less effective at this point because it has become outdated. It only blocks up to 3G signal, and students with smartphones can still use WiFi.

Within the adjacent middle school students to tell a reporter, at 10 PM every day half pipe teacher after the name of these signal jammer to begin to work, the students of mobile phone have no signal, emergency call function can’t use, it was not until the next day morning QiBaDian recovery.

Since a classroom usually is not of very large area, then a portable cell phone jammer is recommended, which is quite convenient to carry and put into use– What you need to do is simply press the button to switch it on. Surely, you needn’t worry about an emergency that someone needs to make a phone call, they can just walk out the classroom and make the call without disrupting others. Or you can just switch off the jammer unit when needed.

A female teacher told reporters that the school did install a jammer in the dormitory building, which was an act of internal management and was a good thing. He said that most of the time is now smartphones, and that many students spend the night in bed playing an all-nighter, and the next day classes are very unspiritual and affect learning. After installing the jammer, the students no longer stay up to play with the phone, and the second day will be better.

Now almost every student in a school own their cell phones. What’s worse, cell phones have become many students’ “weapon” against their teachers. Most students are found using their cell phones to surf on the internet during a lecture; many students tend to listen to music or play video games in classroom; it frequently happens that a sudden cell phone ring during a classroom lecture often arouses distractions; or even worse that some students make use of cell phones to help them cheat in an exam…. It has been reported that a new phenomenon “cyber bullying” refers to that students electronically torment others via text messaging and social networks, when they should be paying attention to lectures.
