    Exploiting the power of the finite element beam propagation method in wireless communication

    Résumé : Wireless propagation modelling is key in wireless systems design. Systems designers are interested in knowing the channel parameters. Traditionally they have employed models such as the free space model, the Hata-Okumura Model, the COST231 model and a host of other models to obtain an estimate of the channel parameters. The FEM has a long history in the engineering field. Initially it was applied to structural engineering problems and in the 1980 extended for use in electrical engineering. It has since found application in many other disciplines. The FEM is a powerful, versatile and accurate method for solving electromagnetic wave problems. In this talk, we propose the use of the finite element method for the characterization of the wireless channel. We show how the FE-BPM may be applied directly to the Helmhotz equation to model tropospheric wave propagation. We also demonstrate how the method might be applied to modelling propagation over forest regions and irregular terrains. Of particular importance to systems designers is how to characterize propagation in built-up areas and in tunnels. We demonstrate some of the results obtained to date and propose its use in other areas such as under soil propagation modelling.
