This paper presents experimental and theoretical characterisation of time of arrival and distance for accurate location detection using different subbands of Ultra Wideband (UWB) radio technology. The error in the measured distance is computed between the geometrically calculated distance (taken as a reference) and the estimated distance using channel impulse response technique. Three different types of compact antennas are used in this study. Studies on different sub bands across whole UWB band shows that the average percentage error in estimation of distance improves by a factor of two, when higher bandwidth (7 GHz) is used compared to lower bandwidth (2 GHz) of the UWB frequency range. Results show that the percentage error of estimation for Time of Arrival is directly proportional to the pulse width.
