Abstract :
Modeling the radio channel has been one of the most difficult parts of mobile radio system design, and is typically done in a statistical fashion, based on measurements. A model developed by Bertoni-Walfisch considers the impact of rooftops and building heights by using diffraction to predict average signal strength at street level (see Walfisch, J. and Bertoni, H.L., IEEE Trans. on Antennas and Propagation, vol.88, no.36, p.1788-96). A new extension method is proposed by extending the technique of Bertoni-Walfisch which is now valid for generalized conditions in mobile communications. The parameters of Bertoni-Walfisch model are determined by measurements in urban areas
