Common Frequenciesįrequency lists for many models of wireless microphones can be found on the manufacturer's websites. NOTE: Operation of wireless microphones on most frequencies in the 614-806 MHz band in the USA is prohibited. Reception thus requires close proximity or use of directional antennas. Wireless microphones in the 600 MHz band that interfere with these new licenses may be required to cease operation in that band sooner than the 2020 deadline. Wireless microphone transmit power levels are normally very low, to reduce the potential for interference. Answer: The FCC has repurposed spectrum in the 600 MHz band for use by wireless services, including bandwidth for smartphones. Many modern professional wireless microphone systems are frequency agile - that is, tuneable to different frequencies - to find clear channels and avoid interference, with most operating within unused television channels. ![]() Cordless microphones or "wireless microphones" can be found transmitting throughout the RF spectrum, most often in the 70-74 MHz, 170-220 MHz, and 580-800 MHz ranges. ![]()
