Hi John,
Wireless Lan from the technology point of view would be 802.11g
There is a Cisco product which would address Fixed Wireless LAN environment 8 mac addresses, you may look at that as an option.
The Cisco Aironet Product has almost full IOS in it, feature rich and very flexible one.
As you said, 5 separate wireless zone, its kind of like 5 VLANs in an switched environments, you can do all these thing easily with Aironet.
Besides, to start with the basics, learn the antennae fundamentals, its very important area to know, in the IP world once u can ping the reachability is achieved, but in wireless that aint sufficient, check the retransmissions ....huh.. Just the reachability is not sufficient.
Don't radiate full power .... Would cause you a lot of issues.
I think you have 14 channels ... Space it properly ... 1, 6 and 11 are non-overlapping channels .....make use of it.
Do not operate in all the available throughputs ..... Do the survey in the top two (one) levels.
Do not go with standard omni antennae, its cheap copper rod, absolutely unpredictable radiation pattern, usually avoid ... Better Antennae can be bought cheaper from regular RF vendors than from Cisco (sorry guys...)
Its amazing to work on the wireless data link ... If have some of the above aspect clear .... Wishing you a great fun working on this new technology.... I just wrote what came to mind, shoot a specific question once u zeroed in on a specific solution.
Thanks and regards,
Raja

Subject: OT: Wireless networking question
Hi Guys,
OT question on wireless networking.
What's a good solution or place for me to start looking at for the following scenario:
Client want's wireless access in a large-ish building (Over 4 floors), area wise at least 10,000 square feet per floor.
Want's to have about 5 seperate wireless zones which can't see each other, as well as a fixed LAN with shared server, intranet, printing and common internet access. Doesn't have to be cisco - also it's a pretty much 100% Mac environment.
Not looking for a solution, just any helpful pointers at areas I can research myself. Any help much appreciated.
Regards,
John
