Boundary Calculator Fresnel Zone Boundary Calculator 
Fresnel zones
While designing microwave link, very important thing is to check if the
first Fresnel zone is free of obstructions. First Fresnel zone is an
ellipsoid of revolution, whitch focuses are in antennas' place 
Link Margin
This calculation gives you the difference between the power of the signal
recieved at the remote end, and the receive sensitivity of the remote end.
From this you can determine the viability of a link. Around 10dBm (better:
10dBm) of margin
is desirable for a reliable link (WLAN antennas)
