This part of IEC 63203-801 specifies low complexity Medium Access Control (MAC) for SmartBAN. As the use of wearables and connected body sensor devices grows rapidly in the Internet of Things (IoT), Wireless Body Area Networks (BAN) facilitate the sharing of data in smart environments such as smart homes, smart life etc. In specific areas of digital healthcare, wireless connectivity between the edge computing device or hub coordinator and the sensing nodes requires a standardized communication interface and protocols. The present document describes the MAC specifications: – Channel Structure, – MAC Frame Formats, – MAC functions.
