Abstract :
In this paper, a software tool has been developed that provides accurate, site specific radio signal predictions for outdoor to indoor or outdoor to outdoor locations. The tool provides results very quickly, and is adept at providing new results for changes in transmitter and/or receiver antenna locations, and building geometries. The propagation prediction tool combines techniques from several different disciplines, including computer graphics and asymptotic electromagnetic theory, to reduce the calculation time without compromising accuracy. Using computer graphics techniques, the time necessary for shooting the rays through the urban geometry is greatly reduced.
