Needless to say, cellphone jammers are also a necessity in prisons. Authorities have confiscated more than 6,000 cellphones in North Carolina’s 55 prisons since 2005, including 443 so far this year. The numbers rose steadily until 2012, when authorities implemented airport-like entrance and exit procedures, such as metal detectors, X-ray scanners and trained dogs, at higher-security prisons. A state law passed after Janssen’s kidnapping that made it a felony to provide a cellphone to a prison inmate also served as a deterrent, authorities said. Some facilities used “managed access,” an expensive system that blocks unauthorized cell signals, in portions of the prison, but Solomon said signal jamming would extend that across entire prisons and be more effective.
While the U.S. military is unlikely to intentionally attack Russian forces in Syria, the situation highlights the importance of suppressing enemy air defenses—one major tactic U.S. flyers have long relied upon is radar jamming, or saturating enemy radars with “noise” and false signals so that they can’t track and fire upon friendly airplanes. The U.S. Navy has relied on the ALQ-99 cell phone jammer system for nearly half a century, even as opposing radars grew in ability. However, by the beginning of the next decade it will begin fielding the superior Next Generation Jammer, boasting significant electronic-attack and signal-intelligence capabilities.
In addition to this. Cell phone use in classrooms is now so rampant that the students now think they have a right to use them during class. They are not listening to instruction and directions need to be repeated many times because they were texting, listening to music on their phone playing a game or watching a video or movie. Some students have even taken or made a voice call during class. In this case, the phone signal jammer should be used.
The powerful ALQ-99 tactical jamming pod first entered U.S. Navy service in 1971, carried by the EA-6 Prowler, an electronic-warfare variant of the A-6 Intruder carrier-based attack plane with a four-man crew. The U.S. Air Force eventually supplemented the Prowler with faster and larger EF-111 Ravens, informally known as Spark Varks because of the intense static buildup their jammers generated.
Cell phone jammers in everyday life may seem like a pretty good idea: Who wants to sit next to someone on the train who’s yammering away to their doctor about the gross details of their last bowel movement? Wouldn’t you get more work done in the library or at your job if you stopped texting your best friend every two minutes?
