Dave,

There is a very good video explaining how RCP (Rural Connectivity
Platform) works at the following link:

<http://blogs.intel.com/research/2008/03/rural_connectivity_platform_be.php
>

Headline: "Intel (r) Rural Connectivity Platform becomes a reality."

"The demo that was presented at the Berkeley Lab open house had two
antennas transmitting video via WIFI connection. One of the antennas
was on top of the Space Sciences Laboratory (SSL) at the UC Berkeley
campus which is about 1.5 miles (2.4 km) away from the lab in downtown
Berkeley."
