This Recommendation presents several models to enable the reader to evaluate the effect of vegetation on radiowave signals. Models are presented that are applicable to a variety of vegetation types for various path geometries suitable for calculating the attenuation of signals passing through vegetation. The Recommendation also contains measured data of vegetation fade dynamics and delay spread characteristics.
