Abstract
Experimental characterisation of on-body radio channel for ultrawideband (UWB) wireless active tags is reported in this paper. The aim of this study is to investigate the performance of the commercially available wireless tags on the UWB on-body radio channel characterisation. Measurement campaigns are performed in the chamber and in an indoor environment. Statistical path loss parameters of nine different on-body radio channels for static and dynamic cases are shown and analyzed. Results demonstrated that lognormal distribution provides the best fits for on-body propagation channels path loss model. The path loss was modeled as a function of distance for 34 different receiver locations for propagation along the front part of the body. A reduction of 11.46% path loss exponent is noticed in case of indoor environment as compared to anechoic chamber. In addition, path loss exponent is also extracted for different body parts (trunk, arms, and legs). Second-order channel parameters as fade probability (FP), level crossing rate (LCR), and average fade duration (AFD) are also investigated.

Summary
Ultrawideband (UWB) communication is an exciting and innovative technology that has attracted much attention and experienced considerable growth in the past few years due to its distinctive characteristics It is a low-power, high data rate technology that minimizes multipath interference due to late time-of-arrival. Most UWB on-body channel measurements are performed using two standalone antennas and cables connecting to a vector network or spectrum analyzer which is more a controlled environment and restrictive; in real life scenarios potential UWB body-centric wireless network needs to be integrated with compact sensors and provides efficient and reliable communication channels. The main aim of this study is to investigate the performance of the commercially available wireless tags on the UWB on-body radio channel characterization. The rest of the paper is organised as follows: Section 2 illustrates the measurement settings, and it briefly introduces the UWB tags, Sections 3 and 4 present the measurement results and on-body radio channel parameters and modelling aspects, and Section 5 draws the main conclusion of the presented study
