RCR Wireless News reports that the FCC could hit their goal of $10 billion in 700Mhz auction bids by sometime today. Bidding for the highly desirable "C block" spectrum has hit $3.8 billion, or 83% of the FCC reserve price of $4.6 billion. That's important, given the fact that if the FCC didn't see the kind of money they were hoping for, they'd likely auction off the spectrum a second time without the open access conditions (for what they're worth) attached. Rules require bidders remain anonymous, so it's still too early to tell if incumbents AT&T & Verizon, Google, or some other entity are leading the C Block push, though yesterday's Spring/Clearwire/Google news could make things interesting.
