While many feel installing jammers 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.
If there is an urgent meeting going on and you want no one to attend any unwanted calls or messages during that important meeting, you can avail the benefits of cell phone portable jammer technology. This technology makes it possible for a person to avoid calls as well as messages without switching off the mobile phone. Enabling this technology blocks the signal from the base stations directly and makes it impossible for the person to communicate with the other person via a mobile phone.
Anyway, we can see that most people support teachers using signal jammer. Cell phone jammer block most types of signals, effectively preventing students from cheating, using cell phones in class, etc. Therefore, the rational use of jammers is not a bad thing.
In addition to this. Cell phone use in classrooms is now so rampant that the students now think they have a right to use them during class. They are not listening to instruction and directions need to be repeated many times because they were texting, listening to music on their phone playing a game or watching a video or movie. Some students have even taken or made a voice call during class. In this case, the phone jammer should be used.
