Understanding ZigBee Technology

The video tutorial explains ZigBee technology, a wireless networking protocol designed for control and sensor networks. It covers the origin of the ZigBee name, its functionalities, and applications in controlling lights, switches, and other appliances. The tutorial describes the three topologies ZigBee can operate on: star, cluster tree, and mesh, as well as its two modes of operation: active and sleep. An example of a ZigBee network connecting home appliances is provided, illustrating how paths are dynamically allocated. The video concludes with a brief overview of ZigBee products and their market presence since 2006.
