Today we live in a high technology world, there are many high tech device around us every where. High technology help us to live easily and conveniently. Among them the most common high tech device is cell phone. As technology develops, the cell phone could help us to do a lot of things, it could be used in many ways. It is an electronic device, but more like a friend, a company. That is why we always carry our cell phones everywhere. But too much cell phone noisy also cause trouble to us, especially in some places that silence is absolutely needed, like law court, conference room, church, concert and other places. We need to find a new way to disable the service of cell phones in those places. But it is not easy to achieve our goal, technically it is difficult to ask our telecommunication companies to offer no signal only in those places. But, luckly we have cell phone jammer now. It solves our problems perfectly. Cell phone jammer is a kind of electronic device used to block cell phone signal in a certain working range, so we could disable cell phone service in that certain area.
There are many kinds of cell phone jammers available in Internet. Some are single function jammer, that means it could block cell phone signal only. Some are multi functions cell phone jammers, besides cell phone signal, they could also block other one or more signals like 4G signal, RF signal, GPS signal, wifi signal, UHF/VHF signal and so on. There are also portable cell phone jammer and desktop cell phone jammer. Portable cell phone jammer is small in size, and could cover smaller place. But it is convenient to carry, could be put in handbag or pocket to carry any where. It have built in rechargable battery, and could be use any where after charged. Desktop cell phone jammer is bigger, normally use AC adaptor, it could cover bigger place, normally have more functions. It could be used in a fixed places like conference room, concert, church, library, restaurant and so on. And there are also low power cell phone jammers and high power cell phone jammers. High power cell phone blocker could cover longer distance, it is some kind of professional cell phone jammer.
Of course, more functions means higher cost and higer price. Some small cell phone jammers, which are small in size, could cover shorter distance, while some big desktop jammers could cover a very long distance. They are different in prices, some cost only tens of dollars, while some others may cost you thousands of dollars. To select a suitable cell phone jammer, we must think about many things. First is where to use it. In a fix place, or in difference places. And how big is the place. You konw that every cell phone jammer has a working range, exceed the range it won't block the cell phone signal. Second is what kind of functions you need. Third, you need to consider your budget. Some portable cell phone jammer cost very less, only tens of dollars. But some professional cell phone jammers may cost a lot. |
