Experimental Study of Frequency Characteristics and Spatial Characteristics of Propagation Through Foliage

Coverage prediction of wireless communication systems requires a precise knowledge of how the environments surrounding the base station and mobile station influences radio propagation. In residential and rural areas, vegetation is one of the major propagation loss factors. However, relatively few studies deal with the effect of trees have been reported in this paper. In context of wireless communications, signal attenuation caused by the forest is due to absorption and scattering by branches and leaves of the trees.
