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.
