A Philadelphia man was caught red handed this week for using a mobile phone jammer to keep his fellow passengers on a public transit bus from using their cell phones.
“I guess I’m taking the law into my own hands,” he told a reporter from NBC10 about the illegal jammer, “and quite frankly, I’m proud of it.”
But while today’s news and ensuing outrage online is all over a single man, the practice of jamming cell phones is actually much more commonplace on the rails in both New York and Washington DC. I spoke to two such “jammers” this morning on what led them to buy devices, which range from $40 to more than $10,000 on websites like Jammerall.com. Some boast radiuses of as little as 15 feet while others claim they’re used on military vehicles and for anti-terrorism maneuvers.
A mobile phone signal jammer transmits on the same radio frequencies as the cell phone, disrupting the communication between the phone and the cell-phone base station in the tower.
