Cell phone jammers in everyday life may seem like a pretty good idea: Who wants to sit next to someone on the train who’s yammering away to their doctor about the gross details of their last bowel movement? Wouldn’t you get more work done in the library or at your job if you stopped texting your best friend every two minutes?
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.
Enter the Next Generation cell phone jammer program, the first documents for which were released by the Pentagon in 2004, with the aim of bringing jamming into the digital age. The NGJ had originally been envisioned as an automated pod for use on single-seat F-35 Lightning stealth fighters, which would serve in all three branches of the military. However, this concept proved much more expensive and time-consuming than expected—which could summarize be the F-35 program in a nutshell. Instead, the Pentagon eventually decided to focus on re-equipping the Navy Growlers with the new jamming system, and in 2013 chose the design proposed by Raytheon over three major competitors.
Since a classroom usually is not of very large area, then a portable mobile 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.
