Analysis of the Influence of Different Resolutions on Radio Propagation Models at 900 and 1800 MHz

The accuracy of propagation models strongly depends on the geographical database which is the basis for the predictions. The accuracy of the predictions increases with increasing accuracy in the geographical database. However, a high accuracy in the geographical database leads to higher computation times for the predictions. Thus, more inaccurate predictions are often accepted due to faster predictions. The effect of different resolutions of the geographical database on the prediction accuracy is analysed in this paper. Furthermore, the influence of the carrier frequency (900 MHz and 1800 MHz) on the prediction results is determined.
