Abstract :
The stability of a dynamic narrowband on-body area channel is characterized based on real-time measurements of the time domain channel impulse response (CIR) at frequencies near the 900- and 2400-MHz industrial, scientific, and medical (ISM) bands. A new parameter, channel variation factor, characterizes channel coherence time. Body movement is considered at various transmit-receive pair locations on the human body. Movement has considerable impact on the stability of the channel, a reasonable assumption for coherence time is approximately 10 ms, and there is greater temporal stability at the lower frequency.
