IMHO, 2.4GHz frequency is a relatively "congested" RF band, and the most you
can only have is 3 non-overlapping channels, and that will be a limiting
factor in an enterprise environment regardless b or g. My Panasonic 2.4GHz
cordless phone, my home theatre wireless control, my microwave oven... all
compete for the 2.4GHz range.
802.11a uses 5.4GHz RF, UNII-1 and UNII-2 offer 8 non-overlapping channels
and the air is relatively "quiet" compared to the 2.4GHz band. In 2-3
years, maybe there will be many devices running in this frequency range,...
who knows. So, I still believe .11a will have its advantage over b and g.

Dennis,
It looks like you are doing your homework on the wireless. Make sure
that you don't discount .11g. IMHO .11g will have a far greater market
impact than .11a for WLAN applications. It offers backward
compatability with .11b and offers the higher data rate of 11.a.
Just my $.02
Chris

Several people sent me some excellent links. Thank you all...
Here's what I ended up with...
Cisco - The Aironet 1200 access point can be configured to support any
of
the standards, but they only have 802.11b available right now.
NetGear - They have 802.11b and 802.11a access points, but nothing that
will
do both, which means losing all my current investment in NICs.
D-Link - They have an access point that does both.
I went ahead and ordered the D-link access point and a couple of NICs so
I
could start to play right away; and I'll "upgrade" to the Cisco unit
once
they have a real product offering...
Thanks all, you guys are great...
By the way, if there are any Cisco people on the list who would like to
put
me on a beta list, I'm open to it... :)

There are several good write-ups on the technology on the CCO, so I knew
that; but I was looking for an actual product to play with to determine
if
the 5 MGHz traffic interferes with other systems in my manufacturing
group
(a major concern). Cisco's Aironet 1200 access point has the
capability,
but it looks the antennas and NICs aren't out yet. D-Link has a fully
functioning set-up I can use for my initial testing.

802.11a works at 5GHz and can support upto 54mbps as compared to
2.4GHz/11mbps of 802.11b

Please respond to
Dennis Laganiere
I've been reading about the new, faster wireless solutions. Is
anybody's
802.11a technology ready-for-prime time? I'm ordering a Aironet 1200
access
point to play with, and it should be capable (with the right antenna),
but
I
understand Cisco's product is not out yet... Anybody know anything
about
the new "a" standard?
Thanks...
