Abstract
The stationarity of the body area network (BAN) channel when the subject is sleeping is examined. The authors question the validity of first- and second-order distribution fits to BAN channel gain. Wide sense stationarity tests have an upper bound at 70% probability for a maximum data length of 5 s. For data lengths greater than 5 s, the probability of stationarity rapidly diminishes. It is shown that the BAN channel is inherently non-stationary, and independent of the subject, sensor location and activity.
