Propagation characteristics for a 60 GHz Wireless body area network (WBAN)

The 60 GHz band is an unlicensed band which features a wide communication bandwidth and a low probability of intercept due to high oxygen absorption. The wide bandwidth allows for a high volume of information to be transmitted wirelessly over a short interval of time. The signal confinement in both time and space makes the 60 GHz band an ideal candidate for a covert Body Area Network (BAN). Current and future soldiers can attain enhanced mobility and increased survivability by taking advantage of advancements in V-band WLAN technology. In this paper, we study the 60 GHz propagation conditions associated with a BAN, optimized for interconnecting various subsystems on a soldier. The 60 GHz wireless channel model study presented includes both human and pig measurement results and analytical channel simulations using ray tracing methods. Measurements were made using three different antennas-horn, slot and patch. The characterization of the channel is provided through path loss data and in some cases, S-parameter data from each node at different receiver points on a soldier's body and gear.
