Cell phone was invented at first to talk to somebody when we need. But things changed as time goes by. Now cell phone is not only a phone, but a computer, a portable entertainment device, an Internet terminal, a wallet, a GPS navitation item, a movie center and so on. You can see now every one is carrying a cell phone whereever he goes, sitting, walking, eating, shopping, meeting, every where, every time. So now have you noticed the problem? Is it a problem if someone talk to his cell phone loudly when we are praying in a church? Is it a problem if a cell phone rings loudly when you are watching a movie in a movie center? Or, is it a problem if somebody yell to his cell phone in a library? Yes, we could agree now that the abuse of cell phone will cause serious problem. We must find a way to stop the use of cell phone in some places. To do this, we need cell phone jammer.
