Agreed- interop is a great thing steve, but the problem is that
currently no wimax profile requires any level of interop beyond
simple bridging, which most operators will find that they want to use
the QOS features so they can sell services such as voip.
are these products i mentioned using the 802.16 intel chips? yes. To
me thats what determines if something is Wimax grade or not.

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.
