Review of Wireless Body Area Networks (WBANs)

This comprehensive study guides the researchers to continue research in Wireless Sensor Networks and understanding of patient monitoring systems, protocold, and communication standards etc. This paper covers general wireless body area network (WBAN) architecture, methodologies, communication standards, and challenges to understanding. We summarize the frequency range, bandwidth, channel capacity, and bit rates of different communication standards and look at how to design sensor nodes and coordinator nodes for WBANs.
