Abstract :
In this paper, a ray tracing based software tool has been developed that provides accurate and site-specific radio signal predictions from outdoor to indoor locations. The tool provides results very quickly, and is adapted to find new results for changes in transmitter and/or receiver antenna locations and/or building geometry. 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.
