Effect of Human Body Upon Line-Of-Sight Indoor Radio Propagation

It is of importance to study the fading effects caused by the movement of human body, since these effects become particularly significant when characterizing short-range channels. This paper proposed a deterministic model to investigate the human motion upon line-of sight (LOS) link by using ray tracing technique in a indoor environment. The experimental procedure involves a set of continuous wave (CW) measurements in a corridor, conducted at 10 GHz. A good agreement is achieved between the results of cylinder model and the measurement scenarios. The amplitude results show that human motion affects LOS link for close distance. The distance separating the walls and the obstacle also strongly influences the received signal
