abstract
The Institution of Engineering and Technology 2016. This chapter discusses the various experimental investigations undertaken to thoroughly understand the Ultra wideband (UWB) on/off-body radio propagation channels. These characterisation measurement campaigns were performed in both the anechoic chamber and a typical indoor environment (cluttered laboratory). Effect of human body movements on the channel parameters is evaluated. Apart from measurements in an anechoic chamber and in an indoor environment, when body parts were moving, measurements were also taken on a treadmill machine in order to mimic the scenario of UWB body-centric system applied in performance monitoring for sport and exercise medicine. Radio channel parameters are extracted from the measurement data and statistically analysed to provide a preliminary radio propagation model with the inclusion of pseudo-dynamic body movements.
