Today FCC Chairman Kevin Martin made public the agency’s plans to hold another auction for spectrum. This new auction, called AWS III, would sell off a 25MHz chunk of airwaves in the 2155-2180MHz range. The winner of this spectrum would be required to offer free broadband services to 50% of the population within four years, and 95% of the population by the end of the license term. The FCC did not provide any details on when this auction might occur, but it is scheduled to vote on the matter June 12. There is also no word whether or not this new auction would affect the terms of the unsold 700MHz D Block from the recent spectrum auction. The FCC has asked the public for ideas on what to do with that block of spectrum.
