Could Google build an ad-supported free mobile network?

According to CNN, Google are "very interested" in participating in the upcoming radio spectrum auction.
"Last month Google pledged $4.6 billion to the auction if the FCC would amend the rules applying to "C Block", a part of the spectrum set aside for smaller companies to use. Google wants to keep these airwaves open, so none of the winning bidders can lock them up with proprietary services."

Google's hope were dealt a blow when the FCC refused to approve two of the internet company’s conditions.
"Google had said that it would match the $4.6 billion (£2.3 billion) reserve price set for a 700MHz licence, which could be used to provide wireless broadband internet access across the US from 2009, if the eventual winner was forced to meet four “open access” conditions."
