Physical layer designs for WBAN systems in IEEE 802.15.6 proposals

This paper presents the trend of physical layer designs for WBAN systems in IEEE 802.15.6 proposals. According to the technical requirement of the WBAN task group, many companies and research institutes have proposed physical layer architectures to provide fundamental technologies for the WBAN communication systems. Since there are various service scenarios for in-body or on-body applications, the physical layer proposals include UWB as well as narrowband techniques. Hence we summarize the design issues for the physical layer proposals with the category of narrowband and UWB signals. The key features of the proposals are described with the frequency bands, modulations, and other technical aspects.
