An extended calculation model for shadowing loss caused by a moving human body in 60GHz WLAN

60GHz has been attracting significant attentions for ultra-broadband WLAN applications because 9GHz wide spectrum is available for unlicensed use on a world-wide basis. However, 60GHz has some drawbacks such as significant shadowing loss caused by a moving human body and large free space loss. To develop anti-shadowing techniques in 60GHz, it is required to characterize features of shadowing loss caused by a moving human body and develop a calculation model for performance evaluation of countermeasures against the shadowing loss. This paper describes an extended calculation model for shadowing loss caused by a moving human body in 60GHz WLAN and calculated results are compared with experimental results to confirm its validity.
