Weissberger's model
Estimates path loss from foliage in point-to-point links.
Last updated
Weissberger's model is a radio wave propagation model that estimates path loss due to foliage in a point-to-point telecommunication link. It is categorized as a foliage or vegetation model and is applicable when the line-of-sight path is obstructed by dense, dry, and leafy trees.

Background
Formulated in 1982, Weissberger's model was developed from the ITU Model for Exponential Decay (MED). It is designed for line-of-sight propagation scenarios, such as microwave transmission, where foliage obstructs the path between transmitter and receiver.
The model is specifically intended for situations involving dense, dry, and leafy trees. Its mathematical formulation expresses the loss due to foliage as a function of transmission frequency in gigahertz and the depth of foliage along the path in meters. The model is significant for frequencies from 230 MHz to 95 GHz and foliage depths up to 400 m, as noted by Blaunstein.
