Mobile radio propagation prediction in irregular cellular topographies using ray methods

The performance of a UTD-based technique for cellular mobile radio propagation modelling is investigated in situations of irregular topography and nonuniform building heights. The comparison between theoretical simulation (with limited topographic and ground cover data) and experimental measurements at 851 MHz is encouraging. The UTD-based technique is seen to exhibit a flexibility which is unlikely to be replicated by alternative physical optics based techniques.
