Clearwire has announced plans to operate its proposed national WiMax network as an open access system, and major players like Sprint, Comcast, and Time Warner have apparently already agreed to become resellers on the network. It will be interesting to see how this turns out, as an enormous investment will be required to build the national infrastructure required to meet the promised goals. One of the backers of Clearwire is Sprint, which is losing cellular marketshare rapidly, and may regard Clearwire as its last chance to keep from being broken up and sold.
A national wireless network makes sense only if the operator truly operates it as open. The dangerous part of the proposal is that Clearwire can make any rules it wants, and can change them anytime it likes. If most of the U.S. ends up relying on a single network owner for mobile access, is that a good thing? Again, it *could* work, if competitive service providers truly get treated equally.
Note also that the article talks about very realistic bandwidth projections of 6 megabits down and 3 megabits up for the WiMax system--excellent for mobile access but that kind of bandwidth won't support much video or other high bandwidth, multimedia services, like movie downloads, live HD events, and videoconferencing. We'll still want and need fiber to the premise (FTTP).
