o) they use Cisco enterprise AP's, which are not badly over buffered. I
don't have data on which enterprise AP's are overbuffered.
Note that there's a lot more to this kind

Dave,
About this point that I've seen you make repeatedly:
My biggest problem with all the work so far is that it starts with a
constant baseline 150ms or 100ms RTT, and then try various algorithms
over a wide range of bandwidths, and then elides that base RTT in all
future plots. Unless you

I don't suppose anyone has set up a lab containing several hundred wireless
clients and a number of APs? A stepping stone towards that would be a
railway carriage simulator, with one AP, a simulated 3G uplink, and a
couple of dozen clients.
I wonder how well simply putting fq on each of the

We regularly test out our WiFi Traffic Generator against a slew of
commercially available APs: Netgear, Cisco, Asus, Dlink...etc..
For 802.11a/b/g/n we have a 1200 station emulator:

I have to say that looks very promising as a testbed vehicle. Perhaps
