Kevin Martin, chairman of US telecoms regulator the Federal Communications Commission (FCC), says that neither the re-auction of D-Block 700MHz spectrum nor the sale of Advanced Wireless Services-3 licences is likely to occur before next year. The D-Block frequencies, which have been set aside to create a national emergency communications network, were part of a sale of 700MHz wireless spectrum earlier this year but failed to attract the minimum bid of USD1.3 billion. The auction of AWS-3 spectrum, suitable for high speed mobile services, is currently up for public consultation. ‘I think it’s very difficult to [start either auction in 2008] because in both cases the commission sought… additional comments. For us to complete either of the auctions by the end of this year, I think that makes it difficult,’ Martin said, according to a report from RCR Wireless News.
