Abstract
This paper presents a measurements of the path loss for validation of a statistical model for off-body radio channels in an indoor multipath environment, which considers the distance dependent mean path loss, and describes body shadowing and fast fading components in a statistical way. The measurement equipment and propagation indoor environment have been presented. Two different bodies and five static and two walking scenarios were considered. Measurements were conducted in the meeting room at Gdansk University of Technology for a Body Area Network (BAN) operating at 2.45 GHz with three onbody patch antennas. Preliminary results show good agreement between measurements and simulations. For the static scenarios, the mean path loss can be characterised by path loss exponent in between [0.9, 1.2] and path loss at the reference distance (i.e., 1 m) in between [38, 44] dB. As expected, the presence of the body introduces shadowing, which is stronger in case of larger body dimensions.
