Multi-Components Mobile Propagation Model of Park Environment

This work extends a previously published theoretical propagation model to a park environment and compares measured and computed data for different types, size and shape of vegetation or trees. Horizontal and vertical attenuation values of leaves, trees and branches, as a contribution to total attenuation are separately obtained and effects of each element to total attenuation are assessed. Finally a comparison is done between 900 MHz, 1800 MHz and 2270 MHz. The difference in path loss between the three frequencies has been analyzed for park environment. The result shows that the loss from vegetation which depends on biophysical parameters is substantially higher for the higher frequencies.
