On-body measurements and characterization of wireless communication channel for arm and torso of human

Abstract

This paper discusses the propagation channel between two half-wavelength dipoles placed near a human body. Different parts of the body are investigated separately. Statistical properties of the wireless on-body channel have been investigated. Path loss parameters and time domain channel characteristics are extracted from the measurement data. Path loss models for the arm and torso have been derived. A comparison with a path loss model near a flat, homogeneous medium has been made.
