Diffraction around corners and its effects on the microcell coverage area in urban and suburban environments at 900 MHz, 2 GHz, and 6 GHz

Ray theory and the uniform geometrical theory of diffraction (UTD) were combined to predict the spatial average of signal strength for rectilinear streets in urban and dense suburban environments. The model was compared with data measured at 900 MHz, 2 GHz, and 6 GHz. The results show excellent agre...

More Information
Summary:Ray theory and the uniform geometrical theory of diffraction (UTD) were combined to predict the spatial average of signal strength for rectilinear streets in urban and dense suburban environments. The model was compared with data measured at 900 MHz, 2 GHz, and 6 GHz. The results show excellent agreement between theory and measurements for different bands and different locations. Furthermore, theoretical microcell coverage areas were determined and compared to existing diamond-shaped models at 900-MHz and 2-GHz with the base station antenna located in the intersection. The theoretical and empirical results were in very good agreement.
