Network 3G/GSM/CDMA Killer

Cell phone jamming isn't a new concept but the fact that it can also interfere with other signals, such as police radios, means they're not exactly common-place. In 2010, one Maryland prison installed a cell phone jammer as part of a test -- the aim was to stop prisoners using cell phones to plan crimes happening outside of prison. At present, most prisons in the United States are introducing such equipment. According to statistics, the re-crime rate in prisons decreased by 10% after the use of such equipment.
