A model for urban microcell radio propagation prediction focused on reliable implementation

Abstract

A radio propagation model for microcellular environments is presented. The model foundation is the creation of many different virtual sources, for that reason a technique for limiting the number of sources created without loss accuracy is proposed. The main purpose of this model is achieve an easy and reliable algorithm implementation, then the assignment of a radiation pattern; using ray-tracing, radiative energy transfer (RET) theory or uniform diffraction theory (UTD) depending on the phenomenon; as a source's property is shown. Additionally the path loss prediction is improved regarding ground reflection and including the attenuation effects of crossing trees and buildings. This model would play a key role in planning UHF wireless networks that is the case of future implementation of IMT- Advanced because it computes the essential large scale parameters and regard some shadow fading components.
