Hi Guys,

What is the max clients you have ever tested on the newest Cisco AP's?

I have a setup with about 200 PDA's (802.11b only) and I have a few
1231 Aironets that can handle about 120 before they start dropping
clients.  I am considering upgrading to the newer series.

Bandwidth is pretty small, about 30kb per PDA (just viewing webpage).

Do you think the newest Cisco gear could handle 200 PDA's on them?

No:) Sorry.

Cisco do publish Design guidelines. Maybe search [cisco enterprise
design].
Oh yes, maybe reference design.
Here is one.
"LAN Baseline Architecture Branch Office Network Reference Design
Guide"

Worth looking there (not that specific document I wouldn't imagine)
for
sensible limits.

Also alt.wireless.internet has some people very experienced with
wireless. Not generally cisco but there may be 802.11
limitations to run into on any platform.

I can warrant that none of our APs will support *more* than 200 clients
on any given radio ... 200 is the hard limit.

What is your aversion to using multiple APs for this many clients?

Picture 1,000 people with Wi-Fi PDA's walking into a large conference
room, no bigger than a few thousand square foot.  We have to provide a
TON of access points to support the distribution.

Because these people are sitting classroom style, and like 1 foot from
each other, it is very difficult to distribute a good network without
like 30 AP's, and tons of duct tape as you can imagine on the floor
with all those Cat-5 cords.

Any suggestions?

Re: Max Clients, Stress Test Results from anyone using Cisco Wireless Ap's? (WDS) HELP!!
All the AP's are not going to be using on the same frequency and with RF
power controll you can support a large number of AP's in a "small" area.
With 802.11b you will have 3 non-overlapping frequencies.  A wireless LAN
controller will automatically select the frequencies and set the appropriate
power levels to support high density wireless.  The Cisco WLAN controller
software now supports "micro-cell" technology to support very high density
deployments.

Thanks for the help on the micro-cell deployment.  It just seems so
overwhelming to have to setup 30+ ap's in a room where it will be used
for 2 hours though.  Any other suggestions?

If you have to have this working as part of the conference for
1000 people, get someone in who has done it before.

Will presumably be a bit tough to test in advance?

"like 30 AP's, and tons of duct tape as you can imagine on the floor
with all those Cat-5 cords. "

You could perhaps use dual radio APs and use 802.11a to link
the APs together and 802.11b/g (presumably) for the clients. You
will  of course still need power but that may already be distributed
for you.

Even as a wired network this might need some significant design.
For example - limited CPU power devices, how many can you
have in a broadcst domain?
How many will connect at once - dhcp server performance.

If you want any kind of roaming on top of that you could be in
a world of pain unless you go the whole hog with a managed
system.

Thanks bod43.  It seems like Micro-Cell is my only option.  I could
run POE for the AP's which would help with the cabling requirements,
but man, this seems like such a nightmare.

I am in talks with Cisco to find an expert on micro-cell, so hopefully
that will bring some ideas to the table.

Is there a solution for upgrading or chaining together AP's to boost
the amount of clients they can handle?

Have you had deployments that will handle 200 clients? Was it just web
browsing?  Any other metrics for that 200 client limit?  Thanks!
