This letter presents a quantitative approach to the investigation of subject-specific on-body communication channels. To this aim, propagation at 5.8 GHz has been studied considering 50 realistic digital phantoms, statistically generated from a set of 20 magnetic resonance (MR) scans. Both line-of-sight (LoS) and non-line-of-sight (NLoS) communication links have been taken into account. Mathematical...
The development of ultra low power wireless sensors for customized wearable medical devices requires patient specific information for the evaluation of the on-body communication channel. Direct measurements on human subjects are impractical for many applications. In such cases, numerical techniques for electromagnetic analysis, such as Finite Differences in Time Domain (FDTD), is an attractive alternative...
This paper presents a study of subject-specific radio channels in wireless body area networks (WBANs). The simulation tool is based on a parallel finite-difference time-domain method (FDTD) and is well suited to model radio propagations around complex, inhomogeneous objects including human bodies in WBAN. It is found from our study that radio channel characteristics in WBAN are subject specific when...
