I remember the day when we put a limit of 128 subs per AP...

Yah. Depends on where the data hogs are.

For planning purposes, I assume we'll get 2/3's of advertised throughput from the AP and then plan on 8:1.

In real life you have to abandon the over subscription rate after the planning phase and monitor what's actually happening on the AP's. Averaging hundreds of users together you'll get actual usage that seems in line with an 8:1 or 6:1 ratio. On an individual AP you tend to not have enough capacity for more than 30-50 people, so you can easily get a few statistical outliers in the mix that make actual consumption not line up with the planned over subscription rate.

It goes both ways too....I've seen sites with actual over subscription of 20:1 and everything's working ok, and other actual sites fall apart when oversub was only 4:1.

At what level do you over subscribe your APs? 4:1? 8:1? 15:1? Or something else?

Thanks
