See the sentences just before “Conformance Testing” in:

The deployment, carried out also with engineering construction firm Black & Veatch, has been completed in Boston, New York, Philadelphia, Washington DC, Baltimore, Pittsburgh, Buffalo, Richmond and Cincinnati.

Paul Allen: I’m aware that there are many fixed Wimax links. I’m not sure there are many mobile ones around. I was under the impression those in the US were the first.

I’m puzzled as to why a technology deployed all over the world, WiMax, is seen as a “failure”.
There are existing networks worldwide to “roam” on.
There are many smaller commercial networks in the US to “roam” on. Are there any LTE networks yet available?

People are missing the “sleeping” giant!

(LTE and WiMax are both OFDM based networks.
Given enough demand, some chip maker will have
a dual-mode software defined radio chip-set.)

History may decide that (mobile) WiMAX’s chief contribution was to accelerate the introduction of LTE. I think there are good rasons to prefer LTE, and its adoption in the US could at last give us an almost universal standard through most of the world for a mobile broadband communications system. (I’m not counting wi-fi as a mobile system because of handover problems.)

Sprint being the only carrier to deploy a technology, is the cellular equivalent of the kiss of death.

I agree, we are in thought times for deploying new nationwide cell network, but Intel being of of main supporters behind WiMax will not stand aside on “egg/chicken” situation.
Does any remember what first Centrino did to WiFi deployments ??
