A dynamic characterization of the wireless body-area communication channel, with a person sleeping, is presented. The characterization uses measurements near the 2.4~GHz ISM band; with measurements of eight adult test subjects sleeping; each over a period of at least 2 hours. We consider numerous transmit-receive pair (Tx-Rx) locations on and off the human body for a typical body-area-network (BAN). Three critical issues are addressed: modeling of channel gain, outage probability, and outage duration. It is shown that over very large durations, there is not a reliable communications channel for typical star-topology BAN radio communications; which motivates the demonstration of the feasibility of using alternate on-body, or off-body links as relays when a given link is in outage in a BAN sleeping channel.
