Indeed. I'm no expert in wireless stuff either, but I know a couple  
of things for sure:
  - it's a shared medium. Like original ethernet. So, bandwidth is  
limited, unlike in a switched ethernet, where it depends mostly on  
the backplane-bandwidth of the switch
  - whatever you do with your APs/Repeaters - they all share the same  
spectrum (shared medium, see above)

Who sold them on this "wireless everything stuff"?
I hope it wasn't you ;-)

Indeed.
But wireless is not meant to shuffle around big amounts of data. At  
least, last time I looked. Maybe it has changed with Draft-N - but  
there are no drivers (yet) for Draft-N in FreeBSD anyway, and it's  
still a shared-medium.
Back when we had 10BaseT, files were also much smaller, nobody was  
sending around 20 MB PPT presentations and downloading a DVD ISO in 3  
hours would have been an out-of-body experience.



cheers,
Rainer
