mobile WiFi accesspoint?

Its not 802.16.. based on Atheros so it probably has a modified 802.11 MAC
and custom RF. No systems are yet certified for WiMAX. We will very likely
see equipment show up that is based on 802.16 but is not yet certified by
the WiMAX Forum. That doesn't much matter for 3.65 GHz and doesn't matter
much at all if you want to use it for PtP links.. except that to maintain
compatibility with other vendors you want to try to stay within the two
major standards, 802.16h and 802.11y. Any off-standards gear gear like this
can be useful but it will probably not be compatible with other vendors.
For WiMAX equipment, Airspan is among the leaders. Alvarion, NextWave are
also active but Airspan appears more focused and has preliminary acceptance
by FCC (as mentioned in their recent ruling). Many large vendors are not
focused on 3.65 because it is particular to the U.S. and Canada. However,
as the market develops others are likely to be drawn in because it is
relatively easy to modify 3.5 Ghz systems. You still have to use an 802.16h
type MAC which will take time for some vendors.

this product is interesting as it also supports 3.5GHz licensed.
I wonder if this is 802.16d, or how soon 802.16d (or16e for that matter)
will be available at 3.6? Could 3.6GHz be the band for the first true
wimax deployments in the USA?

In regard to reasonably price hardware, I'm presuming the following are
relevant, but I don't have a clear sense of when the non-exclusive
licensing process will be in place or what other issues remain before
activity starts in that band.
http://www.ubnt.com/xtreme_range3.php4 ("3.65 GHz Unlicensed Wireless
with Contention Protocol")
and
http://www.ubnt.com/ps2.php4
From the ISP wireless list, the Powerstation pricing is:
http://www.doubleradius.com/Ubiquiti-PowerStation2?sc=2&category=4503
Quantity Price
1 – 4 $159.00
5 – 19 $149.00
20 – 99 $139.00
100 – 249 $129.00
250 +$119.00
On page 66 here, you'll see a map showing that much of Washington state
falls into "exclusion zones" where the new uses of the spectrum will be
severely restricted to protect existing uses. But it looks like Seattle
itself is not in one of those exclusion zones.
