Wireless Mic Makers Meet With FCC on Unlicensed Mic Concerns

Representatives of wireless mic maker Sennheiser explained its pursuit of changes to rules for unlicensed use of the TV spectrum after the incentive auction. Sennheiser representatives met with staff from the FCC Office of Engineering and Technology, said a filing in 12-268. On rules for antenna connectors, Sennheiser said the agency should “retain the waiver for unlicensed wireless microphones,” echoing Shure's recent filing (see 1609260061). On rules for measuring output power for Part 15 certified wireless mics, Sennheiser said: “A microphone that meets conducted power [requirements] will meet the same limit when measured as EIRP [equivalent isotropically radiated power], but measurements of conducted power are more precise. Sennheiser does not object to measuring by EIRP, so long as manufacturers are given the opportunity to measure using either conducted power or EIRP.” Audio-Technica also reported on a call with FCC staff. “We discussed Audio-Technica’s position regarding requirements relevant to the use of conducted or radiated power measurements as applied to its products,” said a filing by the company. “We also discussed Audio-Technica’s position regarding the application of Part 15 restrictions and requirements for antennas and antenna connectors as applied to its products.”
