Mobile WiMAX in Europe

This article frames mobile WiMAX as a disruptive technology in the European telecommunications market. The essence of the article is this:

For the past 15 years, American tech giants such as Intel and Microsoft have been largely shut out of the European-dominated mobile phone industry. Not that they haven't tried—Intel (INTC) made processors and memory for handsets and Microsoft (MSFT) is still pushing a pint-sized version of Windows for handheld devices. But the business was still largely controlled by telecom companies such as Nokia, Ericsson, and Vodafone.

Now, with the pending arrival of a disruptive new wireless technology called Mobile WiMAX, the U.S. crowd stands its best chance in years at knocking down Fortress Europe. A kind of Wi-Fi on steroids, Mobile WiMAX delivers data at speeds comparable to conventional third-generation (3G) mobiles but promises to be cheaper to implement because it uses newer, more efficient technology.

Do you think this article is correct? Does WiMAX match the criteria for a disruptive technology laid out by Christiansen in his book?
