Abstract

Connection probability enhancement method based on artificial reflectors has been proposed for millimeter wave communications systems. In order to decide the optimal position of the artificial reflector, 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 (angle 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/0.1<d<4. 1m, 4 cm step). From simulation results on this interruption model, the disconnection probability has been reduced from 100% to 15% by setting an artificial reflector to make an additional path to communicate when there is no reflection path from walls available as a 2nd path to communicate. The disconnection probability has been reduced from 29% to below 9% by setting an artificial reflector to make an additional path when there is a reflection path from walls available as a 2nd path to communicate.
