Jammin' the jammers.
Chinese electronics maker C.T.S. Technology Co Ltd faces a $34.9 million fine -- the largest ever levied by Federal Communications Commission, for marketing illegal devices that block phone calls and other radio signals. U.S. law prohibits devices that block or interfere with authorized radio signals such as telephone calls, GPS systems, Wi-Fi networks or first-responder communications. FCC regulators accuse C.T.S. of marketing 285 models of signal jamming devices to U.S. consumers on its website for more than two years, falsely claiming that some were actually approved by the FCC. The Chinese company sold 10 high-powered signal jammers to undercover FCC personal, the agency said.
