Zigbee is a low-power, low data rate, and close-proximity (i.e., personal area) wireless ad hoc network. Example applications include wireless light switches, home energy monitors, traffic management systems, and other consumer and industrial equipment that requires short-range low-rate wireless data transfer.

The technology defined by the Zigbee specification is intended to be simpler and less expensive than other wireless personal area networks (WPANs) such as as Bluetooth, or more general wireless networking such as Wi-Fi.
