They use MVDDS for downlink. They only use Wimax air interface for uplink and they have to in the 5GHZ region. For fixed broadband wimax can be better because how the frequency selection is done (unpaired spectrum). Since this is upload only, Wimax makes sense.
For all intensive purposes the US carriers are going to LTE. Clearwire has boucoup spectrum, which will probably be repurposed for uplink services and backhaul. Maybe they use LTE better once the microcells come down in price because their higher frequency will make it an issue as those have come to see.
Sorry to be a grammar nazi but after seeing this several times today on various sites the I just have to say that the correct wording is "for all intents and purposes" -- ...as an individual, I have a right to [do] what I think, what I feel, and I think we all have a right to our own destiny as individuals. And I think I have a right to choose mine and everybody else has a right to choose theirs. »jonestown.sdsu.edu
