Statistical channel model for 60 GHz WLAN systems in conference room environment

In this work, a methodology of statistical channel modeling for 60 GHz WLAN systems is proposed and a channel model for the office conference room environment is developed. The proposed methodology takes into account the most important properties of the indoor 60 GHz propagation channel such as large propagation loss and necessity to use steerable directional antennas by the WLAN stations, quasi-optical propagation nature, clustering of the channel, and significant impact of the polarization characteristics. A general mathematical structure of the channel model that supports all the above 60 GHz propagation channel properties is presented. The application of the proposed methodology is demonstrated by development of a channel model for the conference room environment. Inter cluster, intra cluster, and polarization modeling characteristics are defined in accordance with the proposed methodology and using results of experiments and ray-tracing simulations.
