Wimax isnt aimed at phones. Sprint is pushing it in an attempt to be an isp. Wimax will find a place in laptops, desktop modems, UMPCs, camera etc. You will even see it used as a backhaul connection to link remote cell sites to Sprint's network.
It is a seperate network distinct from Sprint's current CDMA/IDEN and future 4g networks.
It is highly likely that Sprint will join AT&T and Verizon in using LTE as a next gen network replacing their CDMA/IDEN network.
I am glad AT&T is finally putting money into 3g again. It seemed like they hit the pause button in 2007.
