Electromagnetic propagation modeling in office environment

Wireless propagation modeling is more and more needed for optimal indoor coverage in complex environment (such as offices, classrooms, etc.). Thus the need to predict electromagnetic propagation efficiently and accurately in the presence of obstacles, allowing engineers to planning efficiently the communicating devices. This paper will present a rigorous electromagnetic indoor propagation modeling based on the FDTD (3D) method taking into account the presence of various obstacles. A comparison between numerical results obtained by FDTD code and Ray Tracing software will be presented and compared with measurement results. Computational performance efficiency of these methods will also be discussed.
