The United States will vigorously develop electronic jammers
Different gps jammer worked in different ways. Active jammers screamed and interrupted radio-controlled bombs with a flood of radio waves on pre-selected frequencies that drowned out the triggering signal. Reactive jammers “scanned and blocked” by monitoring the electromagnetic spectrum – like a human ear in a crowded restaurant listening for a voice that “detonate, detonate, detonate” – and then block the frequencies that blocked it.
The US strategy was defined in six words: “Get it back on the wire.” By neutralizing remote-controlled bombs, jammers would force riotous bomb makers to use more rudimentary triggers, such as command waves. These triggers would theoretically be easier to spot and would bring the triggers closer to their bombs, where they could be captured or killed by US troops.
Prior to this test, the 2010 BOP had conducted a limited demonstration of cell phone jamming with NTIA, in the same field in Cumberland that supported NTIA’s conventionally required study of cell phone interception technologies.
As part of the January 17 test, NTIA conducted an independent assessment of Micro-WiFi jammer technology to determine its effectiveness and interference potential in radio frequency communications. The BOP and NTIA will review the data and analysis results of BOPs and NTIA tests and develop recommendations for strategic planning and possible acquisition.
Cell phones were seized from blocks 1, 2, 3, 4 and high security block 1. A jammer had been installed in the prison room two months ago. Last year, 72 cell phone cases were reportedly registered, this year there are already 64.
Governor Henry McMaster and South Carolina Department of Corrections director Bryan Stirling reiterated their call for cell phone jamming in prisons for a fatal uprising that left seven inmates dead.
As a supporter of cell phone jammers in South Carolina prisons, Stirling has previously said that prisoners’ access to cell phones is no different than access to weapons. McMaster has also supported jamming cell phones in prisons.
