Inhalt:
Analysis results of commonly used propagation models applied to UMTS Ultra High Sites (UHSs) in urban environment are presented. Differences between predicted values and measurements for two specific locations are presented as functions of the distance between the base and mobile station as well as of the elevation angle at the BS. An assessment of the validity range of the different propagation models is done and a proposal for the extension of the models is made.
