I have one client (my MBPro) on the AE/n network.  The MBPro is  
currently 5 feet from the AE/n base station.  The Airport Utility has  
a logs and statistics panel with a "Wireless Clients" tab showing in  
real time, the current stats:

Signal 	-36
Noise	-96
Rate	130

Under the HELP menu, there doesn't seem to be any information on how  
to interpret those values.
When I'm a floor above and about 20 feet away, My Signal is about -85  
to -90 with the noise level staying the same.

Is there info from Apple on how to understand these values?
