Radio Mobile - RF propagation simulation software

In radio communications a Fresnel zone is one of a (theoretically infinite) number of concentric ellipsoids which define volumes in the radiation pattern of a  circular aperture. Fresnel zones result from diffraction by objects at the edge of the circular aperture.
