Resolving the paradox between IEEE 802.15.4 and Zigbee

IEEE 802.15.4 is a standard maintained by the IEEE 802.15 group which specifies the physical layer and media access control for low-rate wireless personal area networks (LR-WPANs). It is the basis for the ZigBee. ZigBee is a worldwide open standard for wireless radio networks and was designed to provide an easy-to-use wireless data solution characterized by secure, reliable wireless network architectures. It has wide range of applications, in...
