Subject: Re: [IP] WiMax whats up?

Even if WiMax was economically viable, it (and no commercial technology on the horizon due to both today's tech and the spectrum policies described by Brett) is not an alternative to fiber except where its really economically vialble to lay fiber such as 3rd world countries or wide open rural areas)

The aggregate shared bandwidth of a WiMax cell tower is at most a few 100Mbps. That is SHARED with 100 - 1000 subscribers.

One fiber can easily deliver gigabits and should be deployed in non- shared architectures (or at least not shared till it hits a non- blocking switch)

So WiMax or any wireless tech that is going to be with us in the next 5 - 10 years is not going to deliver the bandwidths needed for the US to be a modern technological country. It can deliver ubiquity, but not be an alternative to wired/fiber services.

I haven't heard much discussion on WiMax and related wireless technologies on IP lately, just a lot about physical cables or fiber.
