Characterization of the Dynamic Narrowband On-Body to Off-Body Area Channel
Abstract—A characterization of the dynamic narrowband onbody to off-body area channel is presented based on realtime measurements of the time domain channel response at carrier frequencies near the 900MHz and 2400MHz Industrial, Scientific and Medical (ISM) bands. A statistical characterization is presented of received signal amplitude when the subject’s body is standing and walking, transmitted from the body to a receiver, Rx, off the body, with various orientations of the subject’s body with respect to the receiver, and various distances from the receiver. Two locations of the transmitter, Tx, on the human body are considered. The Lognormal distribution provides a good fitting model with and without movement. Further, the stability is characterized based on a measure of channel response variance, which is called here the channel variation factor and can characterize the channel coherence time. The on-body to off-body area channel is determined to be generally stable over a pe...
