The first implementation of Wireless Body Area Networks (WBANs), though at that time, the prototype was named under Personal Area Network (PAN), a term that was originated from Zimmerman and further developed by IEEE P802.15 Working Group. Soon after, the notation of BAN emerged. A group from Philips was among the first to use BAN instead of PAN and has listed distinct features that should be incorporated into the two types of networks. As the applications of PAN or BAN extended from connecting personal electronic consumer goods for the sake of convenience to the user to medical and healthcare applications, BAN has become increasingly popular and is found to be a key element in the infrastructure for patient-centred medical applications.
