FCC Votes to Prohibit Distribution and Sale of Wireless Mics Using 700 mHz
Current users have until June 12 to get off band — Wireless microphones using the 700 mHz band will be following the stand-alone analog TV set into the sunset. — The FCC has voted to prohibit the distribution …
Context & Ripple Effects
This vote closes out a fight that began with the 2007 auction of 700 MHz spectrum, when carriers and investors including Paul Allen's bid vehicle put billions behind the airwaves being freed as analog TV shut down. Wireless microphones were the squatters in that transition — operating unlicensed in a band now sold to Verizon and AT&T, as Bloomberg's framing ('Broadway Must Vacate Airwaves to Make Room for Verizon, AT&T') makes explicit.
It also lands during an unusually active stretch for the FCC: within days of proposing network neutrality rules, opening the Comcast dispute in court, and pressing Verizon on early termination fees, the commission under Genachowski is showing it will enforce spectrum policy as aggressively as it pursues its broadband agenda.
First-order effects
- Current 700 MHz wireless microphone users — broadcasters, Broadway productions, touring acts and venue operators — have until June 12, 2010 to vacate the band or face interference from licensed cellular traffic.
- Manufacturers are immediately barred from distributing or selling new 700 MHz wireless mics, freezing that product line at retail.
Second-order effects
- Equipment makers must re-engineer their wireless-mic lines around other UHF frequencies, pushing replacement purchases through rental houses and venues ahead of the June deadline.
- Verizon and AT&T gain clear air to deploy the spectrum they bought in 2007, converting auction outlays into network capacity while unlicensed users absorb the migration cost.
Third-order effects
- The move hardens the precedent that legacy unlicensed occupants of TV-band spectrum yield to licensed mobile broadband whenever the two collide, making 'clear the band' deadlines a recurring feature of spectrum transitions.
- It signals a more interventionist FCC under Genachowski — willing to pair pro-consumer rulemaking like the neutrality proposals with hard-edged enforcement of existing licenses, after the CableCARD-era drift.
The trend: TV-band spectrum is being systematically reallocated from legacy unlicensed users to licensed mobile broadband, with the FCC's auction-and-clear cycle setting the pace.
