The cell phone was originally invented to talk to someone when we needed them. But things have changed over time. Now the cell phone is not just a phone, but a computer, portable entertainment device, Internet terminal, wallet, GPS navigation item, cinema center, etc. You can now see that everyone is carrying a cell phone where they go, sit, walk, eat, shop, meet, everywhere, every time. So now have you noticed the problem? Is it a problem if someone speaks loudly on their cell phone when we pray in a church? Is it a problem if a cell phone rings loudly when watching a movie in a movie theater? Or, is it a problem if someone yells at their cell phone in a library? Yes, we could agree now that cell phone abuse will cause serious problems. We need to find a way to stop cell phone use 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 cell phone signal emitted by cell phone tower by emitting stronger signal in same frequency. After covering the cell phone signal, all cell phones in a certain area will be turned off and out of service. Cell phone jammer is very useful for us in many public places where cell phone is not welcome. Once we have cellphone jammer, when we don't need noisy cellphone, we just turn on the jammer, all cellphone nearby can not call or receive calls. Cell phone jammer is so good we need to know more about it.
