Connection Probability Enhancement Using Artificial Reflectors for Millimeter Wave Communications System

概要

Connection probability enhancement method based on artificial reflectors has been proposed for millimeter wave communications systems. In order to decide the optimal reflector position, a propagation path simulator using ray-tracing method has been developed. In this paper 802.11ad living room model is used as an example, and it is assumed that Tx antenna beam is fixed while Rx antenna has beam-forming capability. The interruption model assumes that human body crosses over the direct path determined by θ(angel into which human body blocks)and d(distance from Tx), and the simulations have been done for 10000 tries(0°<θ<180°, 1.8°step / 0.1m<d<4.1m, 4cm step). From simulation results on this interruption model, the disconnection probability has been decreased to below 15%.
