On the Importance of Scattering from Poles in Ray Tracing Simulations

For enhancing the latest mobile networks, a more precise approximation of ray propagation in complex environments is necessary to position base stations and optimize network performance. The scattering from a cylindrical metallic object, which could represent lampposts, poles of traffic signs or flag poles, is implemented in ray tracing simulations. In this paper, the addition of cylindrical metallic objects in ray tracing simulations is done via analytically derivable radar cross-sections. Furthermore, objects are decomposed to utilize plane wave excitation in the near field of the object. Implementing this approach results in an augmentation of the channel richness and increases the best available path gain. The comparison of simulation results to measurements indicates that poles contribute significantly and should not be ignored in ray tracing simulations.
