Study of ultra wideband wireless sensors for body area networks

摘要

In this paper, experimental characterisation of on-body radio channel using ultra wideband (UWB) wireless tags is presented. The performance of wearable wireless tags on the UWB on-body radio channel characterisation has been investigated. Measurement campaigns are performed in the chamber and in an indoor environment for comparison. Statistical path loss parameters of nine different on-body radio channels for static and dynamic cases are shown and analyzed. The path loss was modeled as a function of distance for 34 different receiver locations for propagation along the front part of the body.
