Abstract :
A modified two dimensional finite difference time domain formulation was used to simulate indoor radio wave propagation for a base station located indoors. Good agreement between calculation and measurement as well as UTD/ray tracing results confirmed its accuracy. This method required 800 times less memory than 3-dimensional FDTD for a 3 meter ceiling/floor separation with the signal at 1.8 GHz, making it possible to model the effect of furniture on wave propagation inside a building.
