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. Cell phone jammer is a kind of electronic anti cell phone signal device, it could cover and hide the cell phone signal issued by cell phone tower by issuing a stronger signal in a same frequency. After covering the cell phone signal, all cell phones in a certain area will be disable and out of service. Cell phone jammer is very helpful for us in many public places where cell phone is not welcome. Once we have a cell phone jammer, when we don't need cell phone noisy, we just turn the jammer on, all cell phones in nearby can not call out or receive any calling. The cell phone jammer is so good that we need to know more about it. To know more about the cell phone jammer, lets take a look at the following item:40 Meters Range Mobile Phone Signal Jammer Be Used In Car.
