FCC PROPOSES $48K FINE FOR FLORIDA MAN WHO
JAMMED CELLPHONE CALLS DURING DAILY COMMUTEWashington, D.C. – A Florida man who allegedly jammed consumer cell phone service from his car for
nearly two years and interfered with first-responder communications faces a possible $48,000 fine by the
Federal Communications Commission.
Jason R. Humphreys of Seffner, Florida, apparently interfered with these services while commuting along
a section of Interstate 4 in Florida. In taking this enforcement action, the Commission noted that Mr.
Humphreys’ jammer operation “could and may have had disastrous consequences by precluding the use
of cell phones to reach life-saving 9-1-1 services provided by police, ambulance, and fire departments.”
FCC Enforcement Bureau agents identified Mr. Humphreys as the source of the interference by using
sophisticated interference detection techniques. They then worked closely with the Hillsborough County
Sheriff’s Office, which stopped Mr. Humphreys’ vehicle while he was apparently operating the jammer
and seized the illegal jamming device. According to deputies from the Sheriff’s Office, communications
with police dispatch were interrupted as they approached Mr. Humphreys’ vehicle.
Signal jamming devices or “jammers” are radio frequency transmitters that intentionally block, jam, or
interfere with authorized communications, such as cellphone calls, GPS systems, Wi-Fi networks, and
first-responder communications. It is a violation of federal law to market, sell, import, or use a signal
jammer in the United States and its territories, except in very limited circumstances involving federal law
enforcement. While these devices have been marketed and sold with increasing frequency over the
Internet, their use by U.S. consumers is illegal under any circumstances. Unlawful use of signal jammers
could result not only in substantial monetary fines, but also imprisonment.
