The answer is cell phone jammer. What kind of things can the cell phones help us? A cell phone is a computer, a wallet, a movie center device, a music player, a game box, a camera, an Internet terminal, an email sender, a navigator, a TV set, a radio. Actually, as technology develops, it could help us in many other ways, like exercise monitored and so on. But why do we need cell phone jammer? Because we like our cell phones too much, we keep looking at our cell phones all the time no matter where we go. Now the problem comes, what to do for some places that silence is needed? In church, movie center, theatre, conference room, law court, examination room, concert, restaurant, library and many other places we need to keep silent. But we have seen that many people will allow their cell phones to ring and after that they will yell to their cell phones. We must find a simple way to disable the cell phones in a certain place. The key is cell phone jammer. It is a kind of electronic device that could jam cell phone signal, so all cell phones in a certain distance could not work. The cell phone jammer is very good and it is very helpful to us, because it will not do any harm to any devices. It will start to work once you turn it on, and it will stop working if you turn if off. Once it is turned off, all cell phones will come back to work in a minute. Want to know more about the cell phone jammer? Lets take a look at a very popular cell phone jammer, the 12W Adjustable 3G, 4G LTE, 4G Wimax Cell Phone Jammer.

The product that you are viewing is the 12W Adjustable 3G 4G cell phone blocker (4G LTE + 4G Wimax), which owns the ability of blocking the signals of 3G and 4G at the same time.

The isolating signal bandwidths of this device are CDMA (850-894MHz), GSM (925-960MHz), DCS (1805-1880MHz), PHS (1920-1990MHz), 3G (2100-2170MHz), 4GLTE(725-770MHz ) and 4G WIMAX(2345-2400MHz or 2620-2690MHz). And you can select five of above frequency bands you need in a jammer. With 12watt total power, the jamming range of this device is powerful, which can reach up to 40 meters depending on the signals in the given area.

More details are provided at our website. If you are interested in such kind of jammer device just come here. And if you have requirements about selecting the above frequency bands please also contact with us, as we can OEM and ODM the jammer device that you required for you!

The above is a good cell phone signal jammer, and it is a multi-functions jammer. It could jam CDMA, GSM, DCS, PHS, 3G, 4G LTE and 4G Wimax at the same time. More over, it has a very special design: every antenna is controlled by a separate switch. that means, you could turn on or turn off any antenna without affect the other antennas. For example, you could turn off the CDMA antenna, so it will not jam CDMA signal while it jam the others. And if you want to know more about the jammer, please come to our website.
