you cannot determine the frequency by the path length.
to determine the actual frequency you'll require a Spectrum analyzer, made for Gig range ( they are not cheap)
Typically the lower the frequency the farther the signal can travel without impairment.
Approximate max distances
60Gig 1 to 2 Km
38Gig up to 5Km
18 Gig up to 8 maybe 10K
4.5 Gig 20 to 30Km
Also depends on line of site and the transmitted power.
A good way of know the frequency is look at the waveguide or the feed horn. The smaller the higher the frequency.
Google it, to get more information on waveguide sizes.
Hope this helps

You can only determine the microwave frequency if you know what the cycle time is. Frequency is the inverse of the cycle time. The path length in free space would just be a red herring in the question.
