Fresnel Zone¶
There is a theoretical area around the line-of-sight of an antenna, called the Fresnel Zone. Objects that penetrate the Fresnel Zone block some of the signal travelling from transmitter to receiver, causing the path loss to increase. The Fresnel radius at a point along the path is defined in the following equation:

|---|---|
d1 |
distance from one end in meters |
d2 |
distance from the other end in meters |
f |
frequency in MHz |

For a thorough understanding of the Fresnel Zone refer to ITU-R P.526-14.
