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...
This paper presents an experimental characterisation of off-body radio channels using ultra wideband wireless tags for body-centric wireless networks to be applied in healthcare application. The operating frequency of the tags used for this measurement is 5.9~7.25 GHz. Statistical path loss parameters and a path loss model of nine different off-body channels for the propagation in indoor environment...
This paper presents ultra wideband (UWB) off-body radio channel characterisation for both line-of-sight (LOS) and non-line-of-sight (NLOS) communication scenarios. Measurement campaigns were performed in the indoor environment using UWB wireless active tags. The path loss of nine different off-body radio channels for LOS and NLOS communication scenarios is shown and analysed. Results show that maximum...
The paper aims to investigate optimum locations for ultra wideband (UWB) nodes placement on the body for reliable body-centric wireless communications. The performance of UWB radio propagation links is experimentally investigated by considering communications between body-worn base units and off-body access points. Radio channel parameters are derived and analysed for different sectors of the human...
In this paper an experimental investigation of dynamic off-body radio channels based on commercially available UWB wireless tags is presented. The tags operate at frequency band of 5.9~7.2 GHz. A measurement campaign was performed both in the chamber and in an indoor environment for comparison. The path loss for all nine different channels is shown and analysed and the effects of the body movements...
