Radio Channel Measurements in Body-to-Body Communications in Different Scenarios

Abstrakt

This paper presents body-to-body radio channel measurements at the 2.45 GHz band, for different body motion scenarios and on-body antenna placements, and both indoor and outdoor environments. Measurement equipment, investigated scenarios and considered environments are described, an initial analysis of results being presented. The mean path loss and the standard deviation depend on the mutual location of transmitting and receiving antennas, type of dynamic scenarios and investigated environments. In general, the lowest mean path loss value (below 57 dB) is obtained for the scenario where two bodies are walking in the same direction along parallel routes and the distance in between bodies equals 1 m; in contrast, the highest value (over 70 dB) is observed for the scenario where both bodies depart from each other being turned back to back. Moreover, the highest standard deviation value (over 13 dB) is obtained for scenarios with antennas mounted on the wrists, which are the most movable parts of the body while walking, and the lowest value (around 2 dB) has been measured for antennas mounted on the head.
