Is there any current WiMAX gear that offers 4.5 bits per Hz efficiency and 10 MHz channels? If so, which one?

Also, realistically, what's the max bandwidth (up, down, combined?) available on this system? If up/down ratio can be set via profiles, list all of 'em.

Has to be current and satisfy both requirements. I know about Alvarion stuff, but they don't seem to offer this yet.

If nothing meets the requirements, which gear will meet the requirements the soonest, and when?

Wow tough question. Um... not that I know of. May need to up your tip to like $20 and hope for some WiMAX guru to pop by.

I'd love to give you a positive answer, but to my knowledge no current gear matches that spec. Now i could be wrong if a guru does pop in to correct me that would be wonderful. I also am not aware of anything planned for that spec, although some calling around to companies could probably get you further.
I regret not being able to send you a simple purchase link ;)

Frequency Reuse Factor
An uplink data rate per user is minimum 128Kbps and maximum 1Mbps
for data traffic at the cell edge. A downlink traffic per user
between 512Kbps and 3Mbps, respectively.
A frequency reuse factor is specified to 1. A maximum frequency
efficiency is 6bps/Hz/Cell for downlink and 2bps/Hz/Cell for
uplink respectively.

Good, but I already know that the spec supports that efficiency. I need actual equipment (vendor names, model numbers) info for stuff that adheres to the spec.
