And I guess to be a little less oblique.... In theory that should work well
Dave,  If everybody lived in a faraday-cage, rf aneochoic chamber 
above a perfect ground plane it would be very cool... In a real world 
office environment with metal girder construction the multipath 
interference and reflections is... a bitch. I've been working on 
solutions  for that in a number of applications. Maybe one of 
these days I can cut some time out to write a paper on this 
and the tests... :)

But right now I'm swamped... so you have to find me in 
some bar at the conference if you want  to get me to explain 
more :).

cheers,
