A Florida man who allegedly jammed consumer cellphone service from his car for nearly two years and interfered with first-responder communications faces a possible $48,000 fine from the FCC, the agency said in a release Tuesday (http://fcc.us/1iHV3GJ). FCC Enforcement Bureau agents identified Jason Humphreys of Seffner, Fla., as the source of the interference by using sophisticated interference detection techniques (http://fcc.us/1m7XHIX). Hillsborough County Sheriff’s deputies stopped Humphreys’ vehicle while he was apparently operating the jammer and seized the illegal jamming device, the release said. Humphreys’ jammer operation “could and may have had disastrous consequences” by precluding the use of cellphones to reach 911, the FCC said. Signal jammers are transmitters that intentionally interfere with cellphone calls, GPS systems, Wi-Fi networks and first-responder communications..
