A major constraint in the design of wireless body area networks (BAN) and sensor networks is battery autonomy. For nodes with burst-wise transmission autonomy is efficiently achieved by sleep cycles. We have recently proposed an energy detection based ultra-wideband (UWB) transceiver structure featuring an average data rate of 500 kbps with a total power consumption of less than 1 mW. In this work we present an experimental testbed for our design, which is able to obtain over-the-air performance results and allows to directly observe the impact of physical effects of the environment on BAN communication. Based on the testbed we verify the functionality of our modem design in real world scenarios and evaluate its performance.
