So this maximum is the largest poll value over the last 24 hours?
You can see that 9.4 Mbps is the maximum an access point had over the 10-minute period. I think that should reduce the "panic" level that some people about the 300+ Mbps capability of a dual-radio 802.11n AP. These (relatively) low numbers underscore my conviction that controllers with one Gbps uplinks are sufficient for most controller configurations.

The only exception I have heard is one university that is using a lot of custom applications to control the "fat" APS much like a controller would. They still do not have the control that the controller firewall gives us. Bruce From: Frank Bulk [mailto:[email protected]] Sent: Saturday, February 28, 2009 10:43 AM Subject: Re: Aerohive 340AP Bruce, and perhaps others: If you do 5-minute polling of your APs, what's the highest throughput you've seen on your APs? And looking at your controllers, what's the highest average bandwidth/AP you've seen (i.e. if you saw 250 Mbps on a controller that serves 500 APS, that would be 0.5 Mbps)? It's my personal bias that even peak product throughputs don't touch close to what a properly sized controller theoretically could handle.

We now have almost 600 802.11n APs on 3 controllers that are managed centrally from the master controller. We can handle up to 500 APs per controller (2000 per chassis). This allows you to standardize configurations & OS versions. We are supplementing this with Airwave Wireless Management Suite for monitoring. We moved from 450 Cisco 1231G "fat" APs. The centralized solution scales much better for us.

I don't think that we are going to be purchasing anything this year due to the economic downturn but they are on my short list as well as Xirrus and Meru simply because they use non-standard architectures. My personal opinion is that centralized controller environments don't scale very well when you are considering large 802.11n rollouts.

No idea how they are on the likes of fast roaming, etc. But part of my brain yearns for the days when there were no controllers, and wireless life was a lot simpler.
