New fast approach to wideband propagation prediction in picocells

For the design and maintenance of cellular networks of wireless personal communication services a knowledge of the signal propagation in different environments is required. Indoor propagation is one of the most complicated propagation topics based on the specific type of the building structure and materials used. There are two conventional approaches to the modelling: empirical and deterministic. These approaches are overviewed with their advantages and disadvantages. Then a new semi-deterministic approach is introduced. The new model performance and comparison of its results with measurements are discussed as well. An outlook for the future work concludes the paper.
