I'm not sure if that was in my particular location, but I can only assume Sprint stopped adding WiMax capacity in my area when they decided to build-out LTE.
Anyway, I'm glad to hear Sprint is devoting more resources to LTE...
That was all Clear doing the WiMax thing. I heard the same thing as well about some areas. I never really had an wimax coverage. I have a couple of spectrum protection sites some what near me, but they usually located them in the hood so I didn't get to use them.
