Advice on Upgrading of Section of LAN to Wireless

We are trying to figure out how to get a portion of our LAN wireless. We
have 9 users that would be affected by this and the area that would have to
be supported would be about 300 ft.

Our network consists of a T1 coming into the building, then going out to
other buildings using fiber optics. There are 6 small (4-5 rooms) buildings
that are currently using coax and BNC connectors, and we are having problems
with the electrical storms taking out the BNC - RJ-45 devices. The 6
buildings house about 9 users total.

We have done some research and found 3 different types of wireless access
points.

1. 802.11a
2. 802.11b
3. 802.11g

I am familiar with the B and G, but not with the A. And then we found one
that combines A and G. Can anyone give me some advice to what we will need?

Thanks,
Drew

Hi
The current main stream Wireless is 802.11g which is down compatible with 802.11b.

If you do not have users that specifically use 802.11a you do not need it.

Wireless is heavily depending on the envioroment it is not so much an issue of what to
buy but rather how it should be set to provide adequate coverage. It seems to me that
you need a professional consultant to survey the site and give you advice.

Nope "A" has nothing to do with cellular. Generally you would want to
support "B" or "G" with "G" being the newer standard. "B" will be required
if you wish to support users with Windows Mobile Pocket PCs. You may want to
think about "A" if you want the extra security it may provide, by being less
popular.

Another reason to go with "A" is that it will not interfere with a video
sender, so if you are wirelessly transmitting video from one room to another
you'll want to disable the "B" and "G" or go with an "A" mode Accesspoint.
