A wireless body area network with an average
throughput of 500 kbps based on ultra-wideband pulse position
modulation is considered. For a long battery autonomy a
hardware aware system optimization with respect to the specific
applications at hand is essential. A key feature to achieve
power savings is low duty cycle signaling, and its effectiveness
when combined with burst-wise transmission at high peak data
rate. Exploiting this observation, an ultra-low power system
is presented, jointly optimized with respect to application and
hardware specific aspects. Based on an exhaustive survey of the
state of the art literature, its power consumption is estimated
significantly below 1 mW.
