I was looking for some clarification on the capabilities of these devices to allow roaming of clients between AP's. Take a basic scenario of 3 AP's and a single SSID.
I know the AP541N has clustering which uses the Fast Client Roaming Protocol, which basically does a quick re-connect to the new AP. Not quite as seamless as using aironet and a controller, but still pretty good.
How does the WAP321 handle roaming? Obviously without the clustering feature you would have to configure each AP independently. But after setting them up, would it support roaming in a similiar way to the AP541N??
Last question. Would running three standalone Aironet 1141's operate any differently in terms of roaming?
In summary I like the roaming capability of the AP541N but hate the large clunky form factor. I need something that can be mounted in an office environment (ceilings) that will handle easy client roaming. A short disconnect isn't a concern as long as it reconnects on it's own. Wireless controllers are a little out of the price range for this setup.

As you stated, with small business devices you will not be able to get true seamless roaming. That is only available with devices that use a wireless LAN controller (WLC).
Without a WLC any wireless clients would have to disconnect from one signal completely in order to connect to another. To minimize that disconnection time, it is best to configure any wireless client to have both SSID profiles listed as preferred networks and to automatically connect when in range. That way the wireless client when it disconnects from one will automatically see the other and initiate a connect.
With that said something else that you can do within the WAP321 itself is 1) use WPA Enterprise. There is an option for pre-authentication within that portion of the setup. Again not the same as seamless in an Enterprise environment but close.
But those are really the only true options.
As far as the 1141s in standalone. Not being an Enterprise Engineer, my opinion would be without the WLC they are just simple AP's and I don't think seamless roaming would be available.
With the latest release of firmware for the WAP 561, 551, 371, 351 a new
feature was added that would allow customers to upgrade the firmware for
their clustered access points from the main access point.The basic steps
to accomplish this is:1) Download th...
