First Fresnel Ellipse Evaluation

This paper presents the mathematical formulas for the first Fresnel ellipse / ellipsoid, applied to the radio waves propagation. The final purpose is to check line-of-sight path condition and 1
^st
Fresnel zone clearance, in order to use the free space formula for propagation loss calculation and required transmitted power, for a given geographic map and for different parameters of the transmitter - receiver link.
