Abstract :
Ultra Wide band (UWB) is an appealing technology for health care applications. The paper aims to investigate the optimum location for putting sensors on the body for remote patient monitoring. The on-body measurements are performed in both anechoic chamber and in an indoor environment for more than 100 receiver locations for both line of sight (LOS) and non-line of sight (NLOS) scenarios. The on-body path loss model has been extracted from the measured data. Bit Error Rate (BER) for different receiver locations is calculated by incorporating channel impulse responses for each link in Multiband-OFDM based UWB system. The conducted system analysis shows that for LOS case best location for putting sensor are legs and for NLOS case both legs and arms perform equally well.
