Abstract
Ultra wideband (UWB) systems facilitate extremely high data rates over fairly short distances. Notwithstanding the short communication distances, a proper powerloss model is required to knowledgably model and adjust the transmission power of such systems. The extremely wide bandwidth prohibits narrowband pathloss models to be applied to the link budget calculation of UWB systems. The contribution of this paper is the derivation of a novel breakpoint within the vicinity of the transmitter, which is shown to influence the UWB link budget considerably.
