The IEEE 802.15.4a standard for wireless sensornetworks is designed for high-accuracy ranging using ultra-wideband (UWB) signals. It supports coherent and noncoherent(energy detector) receivers, thus the performance-complexity-tradeoffcan be decided by the implementer. In this paper,the maximum operating range and the maximum allowedpathloss are analyzed for ranging and both receiver types, underFCC/CEPT regulations. The analysis is based on the receiverworking points and a link budget calculation assuming a frees-pacepathloss model. It takes into consideration the parametersof the preamble, which influence the transmit power allowed bythe regulators. The best performance is achieved with the codesequences having the longest pulse spacing. Coherent receiverscan achieve a maximum operating range up to several thousandmeters and energy detectors up to several hundred meters
