Latest FCC Rule Changes For Wireless Microphones and In-Ear Systems

June 13, 2010

FCC published an order that prohibits manufacture, import, sale, lease, offer for sale or lease or shipment of 700MHz band (698-806 MHz) wireless microphone and inear monitoring systems for operation in the U.S.

The transition period for wireless microphone users to vacate the 700MHz band (698-806 MHz) ends June 12th, 2010. After this day, operation of wireless microphones or IEM systems in this frequency range must cease, operation is illegal and prohibited.

The future operating bands for wireless microphones and IEM systems will be the core TV bands.  In Doket DA 10-92, FCC ruled, that….

“… any person who manufactures, sells, leases or offers for sale or lease wireless microphones and or other low power auxiliary stations operating in the core TV bands must display a consumer disclosure text.”



Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.

Purchasers should also be aware that FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC´s wireless microphone website at
