The FCC finished the week with its first request for information in its decision on whether or not to approve AT&T's buyout of T-Mobile. A set of 50 questions will check how AT&T's wireless spectrum is being used, the nature of its overall network, and why it believed it needed T-Mobile's spectrum to meet its goals for 4G. Officials at the US agency also wanted to know what AT&T had considered, if anything, as a solution to its airwave demands instead of making the $39 billion proposal.
