Abstract :
The growing trend towards high bandwidth wireless services operating in the millimetre-wave frequency band requires the development of new models and modelling tools for accurate prediction of coverage. This paper presents a simple model of LOS visibility as a function of transmitter and receiver heights for urban environments parameters derived from a 3D building. A comparison is made with similar coverage plots generated using ray tracing techniques on the same data set. Limitations and means of improving the prediction accuracy are discussed.
