Summary:
As link quality in 60GHz WLAN is significantly affected by moving human body shadowing, it is required to introduce shadowing countermeasures such as diversity and fast session transfer. For performance evaluation of these techniques in various environments, we need a deterministic shadowing model for ray-tracing simulations rather than a traditional empirical shadowing model based on experimental data. With this motivation, this paper proposes a twin cylinder model for moving human body shadowing in 60GHz WLAN, where three knife edges for diffraction loss calculation are derived from geometrical positions of a moving human body, a transmitter and a receiver. It is confirmed that calculated results using the proposed model agrees to measured results.
