The entire point of WiMAX may be interoperability, but from a fixed
wireless standpoint interoperability is meaningless. When and if mobile
WiMAX becomes interesting interoperability will be important. Until then
there is no need for it in a fixed wireless network, so the
certification badge isn't desirable. What is desirable is the
capabilities of the radios. We certainly want to see 802.16-based radios
in 5.8Ghz.

If a system hasn't been through the interoperability testing, it ISN'T
WiMAX - at all. Absent the certification of interoperability, at best
what the vendors will be shipping and selling prior to achieving
certification is a proprietary product with perhaps some "WiMAX
features".
Vendors have been known to change their mind about guaranteeing
"upgrade to final specifications" and likely a number of vendors will
ship products and completely eschew the formalities of WiMAX
interoperability certification. Nothing wrong with that unless they
try to pull a fast one trying to associate such products with WiMAX,
implying interoperability, where none is actually guaranteed.
There is not, and cannot be, 4.9 GHz "WiMAX" products because there is
not, nor is there likely to be, a WiMAX Forum profile for 4.9 GHz
given that band is US only, and the US is projected to be a minor
market for WiMAX gear. So those vendors that claim to be, or soon will
be, shipping "4.9 GHz WiMAX" gear are in fact shipping a PROPRIETARY
system; absent WiMAX certification, there's no guarantee whatsoEVER of
interoperability.
The entire POINT of WiMAX is interoperability!
The market is going to have to sort out the vendors who falsely claim
"WiMAX" for their systems; apparently the WiMAX Forum has no intention
of doing so.
Thanks,

That is correct, however those companies are expected to be shipping
product ( and are taking pre orders ) that will comply with the
testing whenever the gods at wimaxforum decide to get off their
collective arses and certify 5.8. Airspan for example, already has
wimax 4.9 product and is getting FCC certification. So in conclusion,
yes on product, no on the interop profile or tests yet.
