School Cell Phone Disruptor
Cell phone jammer is a device used to block mobile devices from receiving signals from their base stations. Cell phone jammers were originally designed for law enforcement and military use, so they could block communication between terrorists and criminals. Once the public caught on to the technology, many people–especially employers–wanted to use it themselves, especially in large cities where it seems everyone is always on the phone.
Many countries allow limited cell phone jamming, including France, India, Mexico, New Zealand and others. Nearly all these countries allow the jamming of cell phones in prisons. Some of them allow it in schools, and even theaters. Many countries with current bans are considering the use of jammers in prisons. While the use of cell phone jammers by private citizens and local businesses remains controversial, a global consensus is forming around the wisdom of jamming cell phones in prisons. Cell phones are not allowed in prisons. Not the inmates, not the guards. They are a huge problem in the prisons, fights, violence, running scams and extortion, threatening calls to the outside, to calling in hits.
When you get a call at a restaurant or the movies or such, you get the hell away from peopel to continue your conversation. Why are some cell phone users so unconscious of what's going on around them? As others have said, just common courtesy will do, but maybe frequent cell phone use is, indeed, ruining people's brains.
