Building-shielding loss modelling

An approach devised for shielding loss calculation and a model derived from it are outlined. The model handles a building of arbitrary dimensions occupied by wireless terminals with a given probability distribution and illuminated by a satellite. Two models for the probability distribution of the wireless terminals within a building are considered: uniform over the whole floor at a given height above it and uniform at some distance from the exterior wall also at a given height from the floor. Analytical expressions for the building shielding loss as averaged over a building of arbitrary dimensions as a function of the elevation angle and the building parameters, such as building dimensions, attenuation of walls, floors etc., are given. Numerical results for some relevant building models such as office-buildings, factories, simple houses etc., are also presented.
