Rob - Please explain to the members of the Board what WiMax is.

Members of this Board - Rob will not comply with the above request, because to do so will either show his lack of understanding as to what WiMax is, or will make irrelevant all his pro WiMax arguments on this and other public boards. Instead, he will re-direct members of this thread (myself included) to find the answer ourselves, or that he has already posted the answer, or to intemperate the public information on WiMax for ourselves. He may choose to ignore this post entirely, but doing so will also be conceding that his WiMax spamming is just that. One thing for certain, he will continue spread his WiMax FUD, clouded by a complete misunderstanding of the technology he so dearly endorses, but will refrain and/or re-direct any attempt to understand (because, of course, he has been touting it is a breakthrough technology that will render data over wireless phone service useless, just wait... its coming....it really is..just read the article...well, some of it...just enough to re-direct.

Go ahead Rob - put me to shame.

Thought you meant 802.20

802.16:

Overview of IEEE 802.16
Task Group 1 of IEEE 802.16 developed a point-to-multipoint broadband wireless access standard for systems in the frequency range 10-66 GHz. The standard covers both the Media Access Control (MAC) and the physical (PHY) layers. Task groups a and b are jointly producing an amendment to extend the specification to cover both the licensed and unlicensed bands in the 2-11 GHz range.

A number of PHY considerations were taken into account for the target environment. At the higher frequencies, line of sight is a must. This requirement eases the effect of multipath, allowing for wide channels, typically greater than 10 MHz in bandwidth. This gives IEEE 802.16 the ability to provide very high capacity links on both the uplink and the downlink. At the lower frequencies, line of sight is not required, giving other tradeoffs.

I don't see anything about mobility in this or on the rest of the WiMAX forum site http://wimaxforum.org/

Now I did not spend days looking, so perhaps I missed something, but again this simple presents an opportunity for overlapping technologies to be used side by side where best suited. Very similar to the Cyberbus example.
