FCC 700MHz Wireless Compliance
In January 2010, the FCC ruled that all wireless microphones that broadcast in the 700MHz frequency band (including any frequencies between 698MHz and 806MHz) must cease operating no later than June 12, 2010. The Commission aims to prevent unlawful interference with public safety entities and commercial users that operate on the 700MHz band following the June 2009 digital television transition and to prevent wireless mic users from suffering interference.

The FCC’s website includes a section dedicated to providing consumers with important information about 700MHz wireless microphones, which can be found at . The Commission provides links to other consumer information, including FAQs, the “Consumer Fact Sheet,” the “Consumer Advisory,” and the FCC’s wireless microphones press release, at

A table is available at that might be helpful in ascertaining whether specific wireless microphones operate within the 700MHz band and, thus, will have to be replaced or retuned.

Finally, a link to the actual FCC decision can be reviewed at Numerous wireless manufacturers are offering or have extended rebate programs. Contact them directly for details.
