How do you define throughput? Do you mean the coding rate the wifi
driver has chosen to use, or iperf/netperf measurements of throughput?
Also, does babel perform its measurements using unicast or
broadcast/multicast packets/frames?

I've got no results on 11n. I've done most of my work on 11g.  I will
see if i've got any results for 11g which might be appropriate.

Maybe
