Abstract

Variation in path loss models with respect to orientation of human body for both line-of-sight (LOS) and non-line-of-sight (NLOS) scenarios for ultra wideband off-body communication is experimentally and statistically investigated in this paper. Results show that for every 1° change in orientation angle between off-body transmitter and on-body receiver, path loss varies by almost 0.097 dB for LOS case and 0.12 dB for NLOS case.
