Abstract

        Fast radio wave propagation predictions are of tremendous interest, e.g., for planning and optimization of cellular radio networks. We propose the use of ordinary graphics cards and specialized algorithms to achieve extremely fast predictions. We present a ray-optical approach for wave diffraction at building edges, exploiting the programming model of graphics cards. Prediction time is about a quarter of a second in a 7 km^2 urban area with a mean squared error of less than 7 dB when compared with measurements.
