Integrated Intelligent Research (IIR) 64 Comparison of Propagation Models for Small Urban Cells in GSM Network

Abstract — It was summed up purpose of this work is to compare the models of spread for the small urban cells in GSM, with objective to test their behaviour. Engineering radio constitutes one of the most important aspects during the deployment of a cell network as much as it is responsible for the quality level of service given to the subscribers. In environment to indoor, the sign is subjected to different weakening that can attain 30 dB. In effect, the spread in this middle depends on several characteristics to know the architectural data of buildings, in other words types of used building materials, the size of the windows, etc. We are interested in this paper to introduce different models of prediction of urban spread in environment. After different comparisons, we concluded that the model of COST-CNET is the most appropriate to make a prediction of weakening for a local zone with strong concentration.
