It's actually conversations like this that give me hope for WiMAX in the US. Having met WiMAX engineers in Europe and Asia, smaller nations such as India, Pakistan, and Saudi Arabia, have been making far greater strides in WiMAX deployment than the US has. This is for two reasons, smaller geographic area and differing economic conditions allowing a more rapid deployment.

The sheer size of the US is prohibitive in deploying any network regardless of technology. Urban areas will almost always see deployments before rural areas do. Having multiple carriers with the same tech will also speed deployment than one single carrier. Up until recently, XOHM has been going it alone. Sprint/Clearwire changes things (albeit, arguably "slightly")

I'm still weighing in with allnameswereout on this discussion. The US is not indicative of WiMAX's success worldwide. There is room enough for both LTE and WiMAX in the US.
