Abstract
A method is presented for precisely evaluating signal propagation loss on the human body between transceivers in near–field coupling communication (NFCC) that uses the surface of the human body as a transmission path. It is important to assess the loss of signal propagation on the human body to design stable and reliable NFCC networks. We measured signal intensity to compare two methods of measurement with a battery-powered transmitter and an AC-powered signal generator. The results revealed that the AC-powered signal generator affected the communication path. Furthermore, we successfully found a distance dependence of signal loss between transceivers on the human body. We clarified the necessity for properly setting the transmitter power and receiver sensitivity that corresponded to the distance dependence of signal loss.
