The basic principle of cell phone jamming devices is to emit the same radio frequency signals as cell phones. Because of the same frequency, the phone can’t tell which signal is the regular base station signal, thus achieving “interference”. As long as there is a machine with the same frequency as the phone, it makes a lot of “noise” when the base station tries to connect to the phone. You will find that the signal from the phone is unrecognized, so you will refuse to communicate with the phone.
In this modern society, with the fast development of internet, the function of computer and mobile phone has developed, too. People have not only regard them as the basic communication tool, they have treated them as the necessity even best friends in their daily life. They can do lots of things in it. Especially when we welcome the coming of smart era, smart machines, smart mobile phones, smart robot, etc. While behind the smart devices, people become more lazy, more indifferent, more cold and more strange. Sometimes we really need such selectable cell phone signal WiFi .GPS jammer to get us back to the reality life.
Most people don’t understand the difference between bluetooth, wi-fi and mobile data. It seems to be wireless communication technology, but the main difference between them is frequency band. In the mobile communication technology, 2G mainly works in the band of 900-1700mhz, 3G works in the band of 1900-2100mhz, and 4G works in the band of 2300-2500mhz. Bluetooth and WiFi work in 2.4GHz.
Russia has very advanced capabilities to disrupt GPS. Over 250,000 cell towers in Russia have been equipped with GPS jamming devices as a defense against attack by U.S. missiles. And there have been press reports of Russian 4G jammer in both Moscow and the Ukraine. In fact Russia has boasted that its capabilities “make aircraft carriers useless,” and the U.S. Director of National Intelligence recently issued a report that stated that Russia and others were focusing on improving their capability to jam U.S. satellite systems.
