A recent FCC NPRM on wireless microphones (http://bit.ly/ZymDj0) “takes a long-term view” of associated issues, while recognizing the importance of the devices, Mitchell Lazarus, a lawyer with Fletcher Heald, said Friday in a blog post. The FCC “asks for extensive…

and detailed information on how wireless microphones work and what spectrum they use today,” Lazarus wrote (http://bit.ly/1yWtQJH). “The NPRM goes through a catalog of possible alternative frequencies to the TV bands, asking about the suitability of each for wireless microphones and whether rule changes would help to improve that suitability while still protecting other users. Many of these alternative bands would require the development of technologies not currently used by wireless microphones.” Production microphones and performers’ ear monitors have “particularly demanding requirements: extremely high audio fidelity with very low latency,” he noted. These requirements are incompatible with significant data compression, requiring “relatively high radio bandwidth,” he said. “Many of the alternative bands suggested by the FCC are too narrow for these critical applications, but may be suitable for other production needs."
