Although several telecommunication companies have representatives in attendance, and although the FCC's 700 MHz spectrum auction concluded recently, the companies involved aren't yet permitted to divulge certain details of their plans for whatever portion of the airwaves they may have won. The auction is no doubt near the top of many attendees' minds, but those who know the most will have to keep quiet.
