Simple method for outdoor LOS propagation model using ray tracing tools

Abstract

Ray tracing tools used to described the signal scattering and the delay happened in the urban street with a low base station are shown to be characterized via MATLAB program using a set of Digital Terrain Model (DTM). The path loss exponents for line of sight condition, has been developed to estimate a field of view from single transceiver to compute the delay between the source and receiver. The frequency and the road width's affects on the path loss are discussed. All sensible explanation for the results is also presented and discussed. © 2006 Asian Network for Scientific Information.
