Radio Propagation Modeling for Body Surface to External Communication Scenario

Internet-of-Things (IoT) is technology that promises to connect every thing. IoT for human health monitoring is particularly of interest as it promises to revolutionize health care. And that is possible with the integration of wireless body area network (BAN) with IoT. Radio channel play an important role in designing efficient transceivers for IoT capable BAN sensors. Recently, multiple researchers have worked on modeling the radio propagation in and around the human body. Such measurements not only help understand the signal propagation, which is the obvious outcome, they also help researchers design efficient and optimized transceivers. Thus, in this paper, we measure the path loss in a body surface to external scenario for the 900 MHz band in indoor scenarios and model it into a simple pathloss model. The results in the article have been compiled from more than 15000 measurements in typical real-life scenario.
