Abstract
60 GHz millimeter-wave communications have been considered as one of the most promising wireless transmission technology in the future. Compared with the received power in the presence the line-of-sight (LOS) path, it is apparent that the power of non-line-of-sight (NLOS) path may be attenuated seriously, leading to the poor signal to noise ratio. One feasible approach to combat the obstacle transmission in 60 GHz communications is to use a relay device, which is served as the accessing point. In this article, an efficient method is suggested to improve the link quality, by using an artificial reflector under NLOS path so as to avoid significant path loss. This proposed method can be easily implemented in the 60 GHz wireless personal area network, and has a much lower configuration cost compared with the relay node. The theoretic analysis and experimental simulations have demonstrated the effectiveness of the presented method.
