They will certainly want to bid on some, but I suspect they will be more interested in more n41 spectrum when it goes to auction. FCC needs to get moving if this will be done before January 20th will a possible political change. Thete are many areas where they only have 55Mhz contigous b41 spectrum.
Not necessarily. Depends who bids for it, how much they get and what they have to pay for it.
Had the merger not occurred (with Masa failing to infuse any cash into the business), Sprint would be in an even worse position as T-Mobile could have picked some up, unless AT&T or Verizon grabbed it all. Sprint was already circling the drain. This would have finished them off in my opinion. Sprint didn't have the money for lowband, and it wouldn't have had the money for this spectrum either.
The efficiencies realized through merger synergies should allow T-Mobile to pick up some if it wanted to.
