The Federal Communications Commission (FCC) will put aside its work freeing up TV white spaces until Microsoft and broadcasters reach an accord on sharing the spectrum for wireless broadband, FCC Chairman Ajit Pai told the House Communications Subcommittee. He cited “tricky” technical and policy matters the agency needs to address even as Microsoft and TV stations try to find middle ground on the band’s use.
Pai was asked by Rep. Morgan Griffith (R-Va.) about the status of the white spaces “experiment,” who said that probably every part of his district has such white spaces. Pai said he had seen the promise of white spaces technology in places like South Boston, Va., a town in rural southern Virginia,
The chairman said there had been a lot of “tricky” technical issues and policy issues the commission had been hammering out (a number of them involving how to use that spectrum without interfering with licensed broadcast transmissions nearby).
The FCC in March resolved a number of petitions to reconsider the remote sensing database works, which is how unlicensed mobile devices can use the spectrum without–hopefully–interfering with TV station signals. So far broadcasters have questioned the efficacy of that process.
The FCC is permitting the use of white space devices (notably computers), both fixed and mobile, in unused channels, ch. 37, guard bands between broadcast and wireless spectrum and between uplink and downlink spectrum in the 600 MHz band–which they are sharing after the incentive auction.
It is part of the FCC’s focus on freeing up more spectrum for advanced wireless and closing the rural digital divide, which computer companies argue “white spaces” play a key role.
Pai praised Microsoft, the prime mover behind a white spaces rural broadband project, and the National Association of Broadcasters, who have agreed on a number of outstanding issues, though not on Microsoft’s desire to use adjacent channels, which NAB has argued is too close for comfort.
“If there is a consensus that allows us to move forward, we would like to do so,” he said, though he could not provide a timeline.
