Communication Method of Implant BAN for Medical Application

In this study, aiming at implant BAN realization, we developed in-body to on-body channel models for an anatomical human body model in 400 MHz band and UWB low band, respectively. With these channel models we investigated the modulation/demodulation schemes suitable to the in-body to on-body transmission, and developed an in-body to on-body transceiver for experimental validation. Based on a comprehensive consideration on both the communication performance such as BER and the human safety evaluation by SAR, we clarified the maximum data rate and permissible transmit power in the two frequency bands. Moreover, we also proposed the adoption and demonstrated the usefulness of diversity reception on improving the BER and SAR at the same time
