The companies looking to make the spectrum deal have apparently wised up to the fact that it won't be rubber-stamped. They have "committed to go beyond the requirements of the Commission's orders in this matter by taking additional steps to facilitate third-party review of the record materials," which translates into providing their documents in a searchable electronic form. Add it all up and the FCC says it needs an additional 21 days to review everything before making a decision on the deal.
Although it's not necessarily an indication of how the FCC will rule, it's another sign that the FCC seems to be taking its responsibilities to shepherd the use of spectrum more carefully. After seeing AT&T's attempted buyout of T-Mobile fall apart, it's no surprise that Verizon and SpectrumCo appear taking this process a bit more seriously now.
