We're having issues with a microwave link (2.4ghz, but not WiFi) between two 
buildings about a mile apart in Oro Valley.  When the link was put in, the 
line-of-site was clean, but in the 10 years since, there has been so much 
construction that roof lines between the two antennas now impinge upon the 
Fresnel zone and throughput has dropped significantly.  For political reasons 
we can't raise the antennas.

What I'm saying is that you need to be absolutely sure no new growth of trees 
or new construction will interfere with your microwave links.
