For Immediate Release
FCC FINES FLORIDA DRIVER $48,000 FOR JAMMING CELLULAR &
PUBLIC SAFETY COMMUNICATIONS DURING WORK COMMUTE
  --
WASHINGTON, May 25, 2016 – The Federal Communications Commission today issued a 
$48,000 fine against Jason R. Humphreys for using a cell phone jamming device in his car during 
his daily work commute to and from Tampa, Florida.  Mr. Humphreys’ illegal operation of the 
jammer continued for up to two years, caused interference to cellular service along Interstate 4, 
and disrupted police communications.    
“This case highlights the danger posed to public safety by use of a single signal jamming device, 
which can disrupt all wireless and public safety communications in the area,” said Travis 
LeBlanc, Enforcement Bureau Chief.  “These devices may not be used by the public under any 
circumstances.” 
FCC Enforcement Bureau agents opened the investigation after receiving an interference 
complaint from a local wireless service provider. Using FCC equipment designed to detect the 
source of the interference, the agents identified Mr. Humphreys while he was using the jammer 
during his commute.  Enforcement Bureau agents worked closely with the Hillsborough County 
Sheriff’s Office, whose officers stopped Mr. Humphreys’ vehicle while he was operating the 
jammer.  In April 2014, the Commission proposed to fine Mr. Humphreys $48,000 for illegal 
signal jamming.  Mr. Humphreys failed to respond to the proposed fine.  Today’s order fully 
affirms and imposes the $48,000 fine. 
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 United States Armed Services 
or the United States Department of Justice.  Cell and other signal jamming devices operate by 
transmitting radio signals that overpower, block, or interfere with authorized communications.  
Jammers are designed to impede authorized communications, thereby interfering with the rights 
of the general public and legitimate spectrum users.  They may also disrupt critical emergency 
communications between first responders, such as public safety, law enforcement, emergency 
medical, and emergency response personnel.  Similarly, jamming devices can endanger life and 
property by preventing individuals from making 9-1-1 or other emergency calls or disrupting 
communications essential to aviation and marine safety.  
To report the sale or use of an illegal jammer, contact the FCC through the FCC online complaint 
portal.  Additional information, including the FCC Consumer Alert on the jamming prohibitions 
and the FCC Enforcement Advisories regarding illegal signal jammers, is available at
