Comparison of Various Urban Radiowave Propagation Models With Measurements

Abstract

A measurement campaign performed at 1.8 GHz in an urban environment of the city of Cartagena, Spain, is presented. The measurement procedure and data analysis are properly described. The experimental results are then compared with various urban propagation models in order to study their validity in predicting radio signal losses. The analysis shows that different considerations assumed in the models such as the type of wave incidence that is impinging over the series of buildings (plane or spherical) as well as the number of the latter existing across the different propagation paths can be significant in order to obtain more precise and realistic predictions of signal losses.
