Full-wave characterization of indoor office environment for accurate coverage analysis

This paper presents a full-wave characterization of an indoor office environment at wireless local area network (WLAN) and worldwide interoperability for microwave access (WIMAX) frequencies using finite-difference time-domain (FDTD) numerical technique. The aim is to demonstrate the applicability of accurate full wave oriented approach for large scale propagation prediction in contrast to conventional approximate ray models. Numerical simulation were carried out using a 3D full-wave electromagnetic solver SEMCAD-X and simulated results including pathloss and small scale fading characteristics are validated through multiple-input multiple-output (MIMO) channel measurements. The simulated and measured results are found to be in close proximity of each other.
