Field: Telecommunications (Electrical engineering)
Classification: CPC H  G  Y | IPC G  H

Claim 6:
7. A method comprising:
establishing a range between a pair of Ultra-Wideband (UWB) transceivers comprising a first ultra-wideband (UWB) transceiver with a second UWB transceiver using a process in execution upon the first UWB transceiver and the second UWB transceiver; wherein
the range is established in dependence upon a process in execution upon the first transceiver which employs an estimate of an elapsed time for an echo signal established by a digital signal processing (DSP) circuit forming part of the first UWB transceiver; and
the echo signal was generated by the second UWB transceiver; wherein the process comprises:
transmitting an ultra-wideband (UWB) impulse with the first UWB transceiver operating with a first clock rate having first integration windows in dependence upon the first clock rate;
receiving from the second UWB transceiver the echo signal which was generated by the second UWB transceiver in dependence upon its receipt of the UWB impulse;
integrating received UWB signals within the first integration windows and determining when the received energy within a first integration window exceeds a predetermined threshold that the echo signal has been received;
passing the integrated energies within the first integration windows to the digital signal processing (DSP) circuit; and
establishing the estimate of elapsed time with the DSP circuit.
