Impulse radio ultra-wideband DC power modeling

Abstract

Several IEEE standards for modern Wireless Sensor Network (WSN) radios make use of impulse radio ultra-wideband (IR-UWB). To keep power consumption to a minimum, pulses are grouped together in bursts. This paper presents a model used to analyze the relationship between DC power consumption, burst length and link budget for both peak and average power limited systems. Such a model is a crucial ingredient in the design of new wireless systems, when designing for maximum achievable distance with low power consumption. The main conclusions in this paper are that longer bursts turn out not to be more power efficient and an average power limited system gives a higher link budget.
