Implant wireless body area networks (WBANs) are becoming increasingly significant for numerous applications in the healthcare and medical sectors. Here an in-body communication model is proposed, based on a 1 mm resolution mesh kneeling position inhomogeneous 30-year male body model in the 400 MHz medical implant communication service (MICS) band. Firstly, semi-empirical path loss models for numerous homogeneous tissues and a heterogeneous human body model are proposed. Then we investigate the bit error rate (BER) performance using the heterogeneous human body channel model. Coupled with link margin analysis, this model can be applied to future implementations and system design research work.
