Precision enhancement in ETSI‐Hata propagation model tuning using experimental data in a dense urban area

Abstract

AbstractIn this paper an enhanced ETSI‐Hata propagation model tuning is presented. The three‐dimensional (3D) digital terrain map (DTM) was included in the simulation process. For the enhancement of the model tuning process and precision verification of ETSI‐Hata model, the real 3D map of the buildings of the simulated area was incorporated over the DTM. Multiple knife edge diffraction method and the antenna effective height method were used to calculate the diffraction loss. This method was applied for a real urban scenario. For every sector in the coverage area, a tuned model was exploited. Using a genetic algorithm, frequency planning for the entire urban area was performed, which resulted in an improvement in the quality of service. Copyright © 2009 John Wiley & Sons, Ltd.
