Characterization of narrowband on-body wireless channels using motion capture experimentation

Abstract

This paper presents the methods and preliminary results of a comprehensive study of the effects of body position and body motion on on-body electromagnetic wave propagation. Experiments entailed 7 human subjects performing 7 activities with 3 different narrowband antenna frequencies and 3 different antenna configurations. Measurements were taken simultaneously with a Vector Network Analyzer and a motion capture system to get accurate correlations between the human body movement and the on-body channel characteristics. The sample of results presented show a distinct relationship between the activity and the transmission signal.
