Abstract :
The purpose of this paper is to investigate the accuracy of path loss estimation of the propagation from roof-top level to street level. From the analysis, based on measurements, it is found that a single diffraction screen combined with a reflection screen utilizing the height information reduces the standard deviation of the prediction error by 2.4 dB for 90% of the investigated heights
