Statistical Path-Loss Model for On-Body Communications at 94 GHz.

A great amount of work on antennas and propagation for body-centric wireless communication has been studied at frequencies up to X band; however, on-body radio propagation at millimeter/sub-millimeter wave frequencies still remains largely unexplored. This paper presents a study of on-body radio propagation at 94 GHz, particularly focusing on the analysis of specific channels such as waist-to-torso and head-to-shoulder links. Measured data are compared with results obtained with numerical simulations emphasizing the sensitivity of the simulated path loss to the positioning of the receivers with respect to the human body.
