Realistic simulation of a wireless signal propagation in an urban environment

Abstract

This paper presents results obtained from a 3D ray tracing electromagnetic model designed to map the signals in a high rise environment (urban) within the same floor and at the floors above and below that floor. Apart from using ray tracing, the dielectric properties of the materials from each floor are included to achieve realistic signal profiles. The simulation is done for scenarios based on a single base-station and multiple base-stations on the same floor and multi-floors. We have refined existing indoor propagating model to obtain realistic signal distribution in a high rise building. New model include the dielectric properties of materials exists in real environment. The simulation program is written in Visual C++.
