In wireless communications, where sensors operate on batteries, the energy consumption must be reduced while considering the communication range and data rate requirements. In this context we analyze and compare, in this study, the UWB and TR-UWB system in terms of the total energy consumption. So, for that, we develop an analytical model to estimate the energy consumption of a UWB system using a TR technique. We then compare the consumption of a TR-UWB system and a UWB system in two different propagation environments. We show that the TR-UWB system is more energy efficient than the UWB system in the chosen environments for LOS. However in case of NLOS, TR-UWB is more efficient when we use a bi-symbol modulation for different ranges of distance in both environments.
