The effect of human body blockage to path loss characteristics in crowded areas

To better design the coverage areas of wireless base stations, this paper reports the long-term fading, shadow fading, and fast fading characteristics of path loss at 4.7 and 26.4 GHz in a crowded area with pedestrians. We clarified that these fading characteristics of measured path loss broadly matches the Nakagami-Rice distribution. As the results of the analysis with two frequencies, we find that the K-factor becomes low with the increase in frequency.
