With the voting on the Federal Communications Commission (FCC)’s ban on the distribution and sale of wireless devices operating in the 700 MHz frequency coming through on Friday, the manufacture, sale, and import of wireless microphones using the 700 MHz band has been forbidden.

Marking the most recent step in the country’s switch to digital television (DTV), the FCC prohibition order clears the way for the adoption of the 700 MHz band for the upcoming 4G consumer wireless devices from carriers like Verizon and AT&T, as well as for communications services for public safety agencies.

While the wireless microphones with 700 MHz band were initially designed to use frequencies between 698 and 806 MHz that are used by television stations (channels 52-69) for broadcasting TV shows, the DTV transition last year stalled the use of these frequencies by the TV broadcasters.

Since the ban takes effect on June 12, 2010, the FCC website has posted an exhaustive list of wireless devices that would be affected.

As a result of the ban, a number of pricey hardware would need to be replaced before June 12. However, the order does not impact the other wireless microphones that work on other frequencies, and corded microphones that are generally used in theatrical productions, sporting events, and church services.
