The FCC has received a "provisional" winning bid for the national "C Block" licenses in the 700 MHz auction underway: The C Block, a national set of about 20 MHz of prime frequency real estate, has received a bid crossing the minimum $4.6 reserve price: $4,713,823,000 to be precise. The overall auction now stands at $13.7b after 18 rounds. This pretty much ensures that the open access, open device rules so fought over and then acquiesced to by major carriers will be enforced, and it's likely to push more openness into existing U.S. cell markets.
