WiMax is All About Money

Now that the technical specifications for roaming are set, WiMax is at the peak of its hype cycle and also at the peak of its confusion. According to WiMax Faces Doubt, Despite Momentum
the challenges WiMax faces are not technical anymore, but mainly economical:

“The challenge that we face over the next three to four years in the WiMax area is that we have to drive the price down,” Maloney added. “All of us have to drive the deployment costs down so we can bridge that digital divide.”

This links to a comment I made on the challenges to create a “cloud of connectivity”. Pieces of technologies might be at disposal, but there is a huge scale up effort (technologicaly, economicaly, politicaly, user appropriation, …) to integrate them together in a valuable and profitable fashion.
