and comsumer electronics applications, and its standardization is still in progress. The WPAN standards such as IEEE802.15.4 and 4a do not meet the WBAN requirements such as energy efficiency on the body, scalable QoS, and inter-networks isolation summarized in Fig. 6.9.1. Due to energy absorption in the human tissue, propagation loss of the WPAN channel is over 50dB, and the channel characteristics strictly depend on the locations in the body [1]. The long-distance coverage of the WPAN makes it difficult to isolate the channel from the adjacent networks. On the other hand, the body-channel communication (BCC), which uses the human body as a communication channel, can achieve low path-loss without body shadowing effect [2]. BCC utilizes lowfrequency bands (under 200MHz) without a large antenna and
