Simulation of radiowave propagation in a dense urban environment

Abstract

One objective of this thesis was to investigate the effect of details, such as the windows of high-rise buildings, on the radiowave propagation in the dense urban environment through modeling and simulations. If adding windows does not significantly change the signal distribution on average, it may not be necessary to build such a detailed model. Simulations are performed using several levels of detail and the results compared to estimate the impact of the fine details on the signal level. A second issue is base station antenna coverage. The antenna gain, half power beamwidth (HPBW), location, and pointing angle should be chosen to give the maximum coverage over a specified sector. Simulations can be used to select the optimums set of base station properties. Specifically this research looks at the coverage from the two sectored antennas versus a single one over a quadrant.
