Fast and accurate path loss prediction is a prerequisite for effective planning and optimization of cellular radio networks [1]. Ray optical algorithms often achieve very high prediction accuracy, see [2], but consume much computation time. However, semi-empirical prediction models suffer from inherent low prediction quality but require reasonable computational effort.
