Although you never use a cell phone jammer, you may know something about it. Phone jamming devices operate by transmitting and receiving radio frequencies, generally the same frequencies of cell phones. Mobile phone jamming devices overpower the mobile initiation devices by transmitting a signal on the same frequency at a high power that the two signals collide and cancel each other out.

The application of cell phone jammer:

Cell phone jammers were originally developed for law enforcement and the military to interrupt communications by criminals and terrorists. It was reported that bombs blew up commuter trains in Spain in 2004 and the blasts in Bali in 2002 were relied on cell phones to trigger explosives. In the war against Iraq, the US Army widely applied numerous cell phone jamming blockers to sweep the terrorists’ homemade bombs and IEDs. Phone jamming devices are proved indispensible in sweeping the enemies bombs. Moreover, mobile phones jammers are good helpers of the Police. Police can block phone calls during a drug raid so suspects can't communicate outside the area. Cell phone jamming blockers can also be used in areas where radio transmissions are dangerous or areas with a potentially explosive atmosphere, such as chemical storage facilities or grain elevators.

With the widespread of mobile phone jammers, they have been adopted by more and more public places, corporations, even ordinary civilians. Corporations use jammers to stop corporate espionage by blocking voice transmissions and photo transmissions from camera phones. Cell phone jammers can be regarded as useful helpers in schools and universities. By blocking cell phone signals, sudden phone rings will no longer disturb the classes. Besides, students cannot cheat by sending text messages to one another during exams. When phone jammers applied in prisons and detention centers, they can prevent illicit communication. Phone jammers can also be seen in workshops. The workshop managers found that some workers using cell phones secretly while working time, which will affect working efficiency. If the workers put too much time on their phones, they will be depressed in their works. Moreover, using cell phones in workshops always involves the security of trade secret. If confidential information of the factory products is given to their competitors by someone's mobile phone, the factory will suffer a huge loss. So cell phone signal jammers are applicable in factories and workshops for the sake of trade secret protection. Besides, cell phone blockers can also be applied in many public places, such churches, cinemas, theaters, libraries, restaurants and cafes since mobile phone jammers are regarded as nuisances in these places. Once a phone blocker is installed, it will create a "dead zone" and all the cell phone in a certain range will be out of service. Worry free for the disturbances of cell phone.
