From what Intel has told me, it's going to try a different route - eventually! The plan is to have all the wireless in CMOS on the cpu, and have it entirely "soft" - that is, some kind of instant configuration loaded into the radio to change its wavelength and the protocols at the same time.

Inbetween, I guess they can get whatever technology they want onto the core, using designs, like this perhaps.

Most people who are actually planning commercial WiMAX for the next two years or so, however, won't be interested in seeing WiMAX on mobiles. They're looking at 802.16d not .16e - and there really isn't any hope of getting .16e approved and validated and into production for another year after that, or maybe two years. We're looking into 2009 before notebooks with mobile WiMAX appear.

Well, a lot can happen in four years... you're right, it could go that way, but right now, I'm not betting like that. I think WiFi and WiMAX mobile are going to be so similar, in power and range and data rate, that either will be equivalent to the other, at 2.4 GHz and 5 GHz.

So the question that matters is: "What happens at 3GHz?" and that's politics!
