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.
