Abstract

A 3D human body blockage model for outdoor millimeter-wave cellular communication Han B. Wang L, Schotten HD. A 3D human body blockage model for outdoor millimeter-wave cellular communication. Physical Communication, 25(Part 2):502-510. Dec 2017. Blocking is one of the most important challenges in exploiting millimeter-wave for fifth-generation (5G) cellular communication systems. Compared to blockages caused by buildings or terrains, human body blockage exhibits a higher complexity due to the mobility and dynamic statistics of humans. To support development of outdoor millimeter-wave cellular systems, in this paper we present a novel 3D physical model of human body blockage. Based on the proposed model, the impact of human body blockage on frame-based data transmission is discussed, with respect to the system specifications and environment conditions. ac.els-cdn.com ac47-95400c448af1&acdnat=1536950496_e5a38b706a7bd8e8c32660210b15710d
