Did you know US Federal Communications Commission (FCC) in February announced [pdf] that they were going to step up their enforcement against GPS jammer devices? They want everyone to know that marketing, sale, and use of cellphone and GPS jammers is illegal. FCC considers these sorts of jammers a safety risk pointing out that they may stop someone in need placing a 911 call or prevent emergency responders from homing in on your location.
This issue has been on the rise since people started using them in classrooms, theaters, restaurants, or business meetings. FCC says:
A single violation of the jamming prohibition can result in tens of thousands of dollars in monetary penalties, seizure of the illegal device, and imprisonment.
If you know a person or a loved one that is using GPS jammers you can turn them in with the info on FCC’s Jammer Enforcement page or maybe show them this poster [pdf]. By the way – 48% of you think GPS jammers should be legal.
