Simulation and measurement of near-ground wave propagation for indoor scenarios

A Semi-analytic model for near-ground wave propagation in the presence of building walls that was proposed in [3] is extended to 3D multi-wall propagation scenarios. The extension to 3D and a method to take into account multiple reflections in the presence of multiple building walls is presented. Measurement results under laboratory conditions for validation using a single concrete wall and different transceiver arrangements is discussed. Field coverage comparison between the new semi-analytic method and an FDTD solver for various cases is also included.
