5GHz Near-Ground Indoor Channel Measurements and Models

摘要

Near-ground wireless channels are becoming increasingly important for a number of applications. In this paper we add to the body of work on this topic, by quantifying small-scale near-ground channel fading characteristics in indoor environments, at 5GHz. Results for delay spreads, multipath component persistence, and amplitude fading are used to develop models for this channel. As expected, the near-ground channel can yield more dispersion and deeper fading than its counterpart with elevated antennas.
