About Cell Phone Signal Jammers

The cell phone jammer device transmits signals at the same frequency and high enough power to overload the mobile phone, so that the two signals collide and cancel each other. The mobile phone is designed to increase power when it encounters low-level interference, so the jammer must recognize and match the power increase of the mobile phone.

Mobile jamming devices were originally developed for law enforcement agencies and the military to interrupt communications between criminals and terrorists. Jammers have played a major role in the past. For example, the bomb that blew up a commuter train in Spain in March 2004, and the explosions in Bali in October 2002 and Jakarta in August 2003 all relied on mobile phones to trigger explosives. According to extensive reports, in December 2003, a mobile phone jammer prevented an assassination attempt on Pakistani President Musharraf. When President Bush visited London in November 2004, it was reported that the British police considered using jammers to protect the President’s motorcade through London.
