I wonder what the PtP backhaul links have been provisioned with in terms of BW. At what point will WiMax users begin to feel a pinch. I wouldn't think that they would lay out all kinds of capital for 10-30Mb of backhaul right off the bat....??
Some WiMAX testers were saying they got 11-14Mbps so they must be supplying a pretty large backhaul. Sprint is conservatively estimating 2-4Mbps when factoring shared usage. But you may be able to peak much higher if on a low used tower. WiMAX also has better latency than EVDO.
