The 700 MHz auction ended yesterday, and the $19.59 billion going to the Treasury looks like a lot until you realize the government’s total budget is $2.9 trillion. But now the waiting (and speculating) can begin. What will happen with the failed auction for the D block, which had been allocated for public safety? Who paid the $4.75 billion for the C block — Verizon, Google (not likely) or AT&T? What will an “open network” look like? As in life, the answer to one question often leads to many more.
