Chinese company fined $34 million for selling signal jammers

The Federal Communications Commission (FCC) finalized a penalty of more than $34 million against a Chinese company Wednesday for selling devices that illegally jam wireless signals.

“In today’s mobile world, cellular, GPS, and other signal jamming devices seriously jeopardize communications, business operations, and public safety,” said Travis LeBlanc, the FCC’s chief of the enforcement. “Marketing or selling these devices to the public is unlawful and comes with substantial penalties.”


The company, C.T.S. Technology, sold a range of jamming devices, according to the commission. Some had a range broad enough to block signals within multiple blocks, it alleges.

The agency said the company falsely claimed that at least one of its products was approved by the FCC.

The fine totals roughly $34.9 million. The agency proposed it in 2014, when it was the largest proposed fine in commission history. C.T.S. Technology had the chance to respond to the allegations at the time but did not, and on Wednesday the commission finalized the penalty.

Jamming radio signals is illegal under federal law except in select instances involving law enforcement. It is also against the law to sell or market such devices.

It is an active area for the FCC. The agency lists at least five other enforcement actions from this year related to the practice, including reaching agreements with organizations that had installed the devices.
