Tuesday at 6 p.m. Eastern time was the deadline for broadcasters to sign up for the auction. Once the FCC knows what spectrum will be available for sale, it will rearrange the frequencies in the band to make room for blocks that are big enough for carriers to use. So viewers may find their favorite channels moved around.
The "forward auction" where mobile operators bid for spectrum is expected to begin in June. It will go on until no one comes up with any higher bids.
The action could get pretty heated, considering this is the last major auction on the FCC's calendar for the foreseeable future. Carriers will be motivated to stock up on frequencies, Entner said. "This is the last stop through that desert."
