Statistical Characteristics Study of Human Blockage Effect in Future Indoor Millimeter and Sub-Millimeter Wave Wireless Communications

The millimeter and sub-millimeter wave communication is a promising solution to future indoor multi-gigabit wireless communications because of its huge available bandwidth. One of the key difficulties is the hu- man blockage effect since the human body can no longer be considered as being "transparent" as at lower frequencies. In this paper a study of statistical characteristics of this problem is presented. At first, broadband measurements of human blockage are provided. Afterwards, a realis- tic mobility model for indoor movements of humans is adopted and elliptic cylinders are applied to approximate human bodies in ray-launching simulations. Consequently, the distributions of Line-Of-Sight (LOS) path and blockage durations as well as blockage numbers are obtained by simulations. Finally, the system performance in presence of the distributed antennas is evaluated.
