Time-variant BAN channel characterization

Abstract

In this paper we present a time-variant on-body channel measurement campaign at 2.45 GHz and in the 3-5GHz band. Measurements were performed in an anechoic chamber and an indoor scenario. Three different human body movements for seven human subjects were considered to assess the influence of human activity on the channel behavior. To this aim, an analysis on mean channel gain, slow fading and shadowing correlation is presented with emphasis on the differences given by the human body variability and the movement condition.
