I will justify my response and modify it slightly. We are a small
college that has big old buildings. We started wireless three years ago
with a very small budget. In order to maximize "bang for buck" we
deployed using mostly directional antennas to cover the largest possible
areas, this also allowed us to secure the AP's in secured rooms. This
model does not work for "a" which has to use a fixed antenna.
Congestion was not an issue for us and is still not, although I expect
this to change in the next two years mainly in the Dorms. In summary,
if low density environment, such as ours b/g, works fine and can cover a
larger area ("b") using directional antennas.
However, all these postings have convinced me that any additional
deployments will include "a"

We have never received a request for 802.11a and most laptops do not
support it built-in. It may be a better technology but for a University
that has to support customers who supply their own equipment in does not
make sense.
Also, Cisco and maybe other vendors (we are a Cisco shop) are using the
"a" frequency to inter-connect access points where hard wired Ethernet
is unavailable (mesh technology). For example a light pole in a parking
lot.

Subject: [WIRELESS-LAN] 802.11a
CU-Boulder is significantly expanding wireless in student and academic
areas. The question has been raised about support of 802.11a. Even
though our new access points support 802.11a it may not necessary make
sense to deploy the technology.
For those who have adopted 802.11a could you answer the following
questions:
1) How much usage of 802.11a do you have vs 802.11b/g?
2) Do you have coverage of 802.11a in all locations where you also have
802.11a or is it provided for specific applications?
3) Has 802.11a generated additional support calls?
