About the Fresnel Zone Appendix D
RADWIN 1000/2000/5000 User ManualVersion 2.6.50p D-14
The amount of the Fresnel zone clearance is determined by the wavelength
of the signal, the path length, and the distance to the obstacle. For reliabil-
ity, point-to-point links are designed to have at least 60% of the first Fresnel
zone clear to avoid significant attenuation.
The concept of the Fresnel zone is shown in figure D-9 above. The top of
the obstruction does not extend far into the Fresnel zone, leaving 60% of
the Fresnel zone clear; therefore, the signal is not significantly attenuated.
