I am not terribly concerned. As long as Sprint has 20-60 MHz of contiguous BRS/EBS spectrum for TD-LTE 2600, everything will be fine. Anything beyond 60 MHz long term is excess.
Some of you root for Sprint to become the clear cut spectrum champ, but that is just not realistic. The other carriers and the FCC will not allow that. In an increasingly consolidated market, spectrum parity/proportionality will be the regulatory goal going forward.
So, have Sprint consent to drop many of its EBS leases within a few years. Let those leases float in the open market. That should appease the FCC. And the other carriers will have no choice but to go along. They talk a big game, as if Sprint has an unfair advantage by hoarding all of this BRS/EBS spectrum. But that is all they are -- talk. They are incredibly two faced. The other carriers do not really want any BRS/EBS spectrum, but they just do not want Sprint to have it either.
Thus, Sprint should let most/all EBS leases float freely in the open market. Then, when the other carriers show their true colors with their disinterest, Sprint may be able to pick up some EBS leases on the cheap. That is the fair way to proceed.
