Discrete propagation model for mobile communications in urban environment

Abstract

The need for wireless communication data has increased considerably in past decades. In this paper we have introduced new propagation model for the streets and avenues in urban areas that can be thought as a waveguide for EM-waves. Using our developed model it is possible to calculate the contributions of each direct and scattered wave separately. We don't assume the sidewalls as perfect conducting materials in our developed model unlike the previous studies. Our simulations revealed that developed model is applicable for broadband of frequencies. If the shape of the wave-guide is entered to simulation program in great detail, the output can be very close to results that are obtained by measurements. Even the shape is not entered very accurately; an approximate result can be obtained if the fast result is needed.
