by way of an fyi - if it has the 802 designator, you might want to
check out the IEEE web site. there are actually working groups which
have these designations and by way of an FYI, they typically have nerds
from a variety of vendors.
candidly, i haven't been following either of these groups too closely.
if you're interested in getting updates on what's going on in them,
here are some useful URLs.
802.16 - wireless MAN technologies. more akin to what the WUG is
interested in doing. supports both licensed and unlicensed portions of
the spectrum and makes some provisions for "L2" centric QoS iirc.
http://grouper.ieee.org/groups/802/16/index.html
802.20 - mobile broadband wireless, targeting licensed spectrum <3.5Ghz
w/speeds in the 1Mbit+ range and support for moving users.
