FCC PLANS $34.9 MILLION FINE
AGAINST CHINESE ONLINE RETAILER OF SIGNAL JAMMING DEVICES
Warns U.S. Consumers that Importing and/or Operating a Signal Jammer is Unlawful
Washington, D.C. – The Federal Communications Commission plans to issue the largest fine in its history
against C.T.S. Technology Co., Limited, a Chinese electronics manufacturer and online retailer, for
allegedly marketing 285 models of signal jamming devices to U.S. consumers for more than two years.
The FCC applied the maximum fine allowed to each jammer model allegedly marketed by C.T.S.,
resulting in a planned fine of $34,912,500.
“All companies, whether domestic or foreign, are banned from marketing illegal jammers in the U.S.,”
said Travis LeBlanc, Acting Chief of the Enforcement Bureau. “Signal jammers present a direct danger
to public safety, potentially blocking the communications of first responders. Operating a jammer is also
illegal, and consumers who do so face significant civil and criminal penalties.”
C.T.S. operates a website that markets consumer electronics to individuals in the United States, where it
allegedly misled U.S. consumers by falsely claiming that certain signal jammers were approved by the
FCC. In fact, the use of such devices by U.S. consumers is illegal under any circumstance. C.T.S. also
sold 10 high-powered signal jammers to undercover FCC personnel.
In addition to the planned $34,912,500 fine, the Commission is ordering C.T.S. to cease marketing illegal
signal jammers to U.S. consumers and provide information to the FCC about any persons and entities in
the United Sates that purchased its devices.
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
To report the sale or use of an illegal jammer, contact the FCC Enforcement Bureau through the FCC
online complaint portal or call 1-888-CALL-FCC (or 1-888-225-5322). To voluntarily relinquish a signal
jammer, please e-mail firstname.lastname@example.org. Additional information, including the FCC Consumer Alert
on the jamming prohibitions and the FCC Enforcement Advisory to retailers regarding the marketing of
illegal signal jammers, is available at www.fcc.gov/jammers.
Images of a sample of the illegal signal jamming devices allegedly marked by C.T.S. are available in the
enforcement action. The FCC enforcement action against C.T.S. is available at:
