Prediction of urban propagation loss

Two significantly different methods to calculate the path loss in urban areas are investigated in order to test their applicability to predicting the received power of a broadband DAB signal for mobile reception. The results were verified by broadband measurements of the received power in a DAB single-frequency network recently installed in Munich. Although these methods use totally different approaches to calculate the path loss, their predictions of the mean received power are of comparable accuracy. However, in order to cope with the need of a coverage for 99% of the locations for a digital service and mobile reception, it is worthwhile to use rather complex methods that are capable of providing information about the local variation of the signal. One such method will be described in this paper
