Abstract: An ultra-wideband (UWB) wireless communication system, comprises a first wireless apparatus; a second wireless apparatus that participates in a first ranging sequence with the first wireless apparatus; and a transmission channel between the first and second wireless apparatuses that transmits data of the first ranging sequence. At least one of the first wireless apparatus or second wireless apparatus generating at least one channel impulse response (CIR) and determining from the at least one CIR whether the transmission channel includes a line-of-sight channel. A special purpose processor reduces a current performance level of at least one of the first and second wireless apparatuses during a second ranging sequence in response to a determination that the transmission channel includes the line-of-sight channel.
