Web2 mrt. 2024 · To simplify, the maximum operating link distance is a function of level of availability desired (for example, 99.999% or 99.99%) and rainfall rates in the geographic area of intended use. Again to simplify, link distance increases as level of availability and rainfall rates decrease. Rain fade is not limited to satellite uplinks or downlinks, as it can also affect terrestrial point-to-point microwave links (those on the earth's surface). Rain fade is usually estimated experimentally and also can be calculated theoretically using scattering theory of raindrops.
