Can a school install signal jammers really organize students to go online?

While many feel installing signal jammer in schools is not a solution as children have access to internet at several other places including at their homes and in open wi-fi zones across the city, some feel it as a good initiative. Children in adolescent years do not have enough maturity to make proper use of internet. Sometimes out of curiosity or under peer pressure they may get exposed to content which they should not. It is a very good initiative to install jammers so that even unintentionally anyone cannot commit such a mistake.

Since a classroom usually is not of very large area, then a portable signal 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.

There are devices which will interfere with the phone signal, in essence pretending to be a base station while not being one. The problem with that is that it disables emergency calls. In theory, you could implement something which switched phones to “manner mode” when they were in a location where calling was not allowed (since the operator always knows where the phones are). But nobody has suggested this either as a product or a standard, evne though it would not be particularly difficult. Perhaps beacuse the ones who would have to pay for it would be the cinema owners, restaurateurs

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.
