I know, it is a work for my diploma thesis. I'm trying to combine it
with some kind of round trip time measurements. It is in the very
early stages,...

That works on my laptop, but on not on my Openmoko Freerunner devices.
There I get the following:

runner1:~# iw dev eth1 station dump
nl80211 not found.

I assume that something with the freerunner wireless driver is not
compatible with the linux wireless stack. The driver is called
"ar6000".
