Abstract

This paper presents ultra wideband (UWB) off-body radio channel characterisation for both line-of-sight (LOS) and non-line-of-sight (NLOS) communication scenarios. Measurement campaigns were performed in the indoor environment using UWB wireless active tags. The path loss of nine different off-body radio channels for LOS and NLOS communication scenarios is shown and analysed. Results show that maximum of 13.62 dB higher path loss of off-body channel is noticed for NLOS communication scenario in compare to (LOS). A least square fit method was performed on the measured path loss results for both LOS and NLOS cases. Increase of 32.17% path loss exponent is noticed for the NLOS scenario.
