Speed of light is slightly less than 1 foot per nanosecond in a vacuum, so 10 
nanoseconds should be 10 feet.  Perhaps it was 50 nanoseconds.  That would be 
49.178 feet in a vacuum.

I don't know if this is still true, but it used to be that air delay was a 
count of 10 nanosecond intervals, and if you multiplied by 49 feet you'd get 
the actual range. 

49 ft/10ns being the speed of the signal through the medium.

  Air Delay on the PTP450 is at:  .1.3.6.1.4.1.161.19.3.1.4.1.24.2

  The current round trip air delay in bits measured between the AP and SM.
