ZigBee is a IEEE 802.15.4 -based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios.he current ZigBee protocols support beacon and non-beacon enabled networks. In non-beacon-enabled networks, an unslotted CSMA/CA channel access mechanism is used. In this type of network, ZigBee Routers typically have their receivers continuously active, requiring a more robust power supply.
The technology defined by the ZigBee specification is intended to be simpler and less expensive than other wireless personal area networks (WPANs), such as Bluetooth or Wi-Fi.igBee-style self-organizing ad-hoc digital radio networks were conceived in the 1990s. The IEEE 802.15.4-2003 ZigBee specification was ratified on December 14, 2004. The ZigBee Alliance announced availability of Specification 1.0 on June 13, 2005, known as the ZigBee 2004 Specification.
