700MHz Wireless Microphones Banned
The introduction of Digital Television (DTV) service in the U.S. on February 17, 2009 resulted in more intensive use of all TV spectrum, both VHF and UHF, as new digital signals came on the air.
In addition, the FCC has reallocated four UHF TV channels for use by Public Safety stations, and auctioned off the remainder of the 700 MHz spectrum for other wireless services. Many wireless microphone systems are still in use that use channels 52-69 (698 - 806 MHz), generically referred to as the 700MHz band.
The FCC now prohibits the use of wireless microphones in this 700MHz range. 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 http://www.fcc.gov/cgb/wirelessmicrophones.
