There is a way to safely eliminate these problems immediately, by using a signal jammer. Learning how signal jamming works on wireless devices will make it possible to clearly understand and appreciate their overall value.
 
Mobiles are great communication tools that are effective and efficient in many ways, but there are still people that use these devices at the most inconvenient times. Within a wide range of different public places (theaters, restaurants, concerts, funeral parlors, churches), people simply do not know when to put their mobile phones away. It can be socially unacceptable for others, who are frustrated by these individuals that decide to do whatever they want, even in situations with clearly marked signs prohibiting cellular use.

A cell phone jammer is a device that blocks reception between cell towers and mobile phones. Developed for use by the military and law enforcement, these devices were originally created to combat threats like cell phone-triggered explosives and hostage situations.

How do cell phone signal jammers work?
Known as cell jammers, signal blockers, GPS jammers, or text stoppers, a cell phone signal jammer holds up the radio frequency in a given area, creating a sort of signal traffic jam that blocks all communication. Like a radio silence bubble, no calls or texts can be sent or received as long as the user is within range of the cell phone signal blocker.

The actual range of the jammer depends on its power and the local environment, which may include hills or walls of a building that block the jamming signal. Low-powered jammers block calls in a range of about 30 feet (9 m). Higher-powered units create a cell-free zone as large as a football field. Units used by law enforcement can shut down service up to 1 mile (1.6 km) from the device.

Cell phone jamming devices were originally developed for law enforcement and the military to interrupt communications by criminals and terrorists. The bombs that blew up commuter trains in Spain in March 2004, as well as blasts in Bali in October 2002 and Jakarta in August 2003, all relied on cell phones to trigger explosives. It has been widely reported that a cell-phone jammer thwarted an assassination attempt on Pakistani President Musharraf in December 2003. When President Bush visited London in November 2004, it was reported that British police considered using jammers to protect the president's motorcade through London.
