Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks (PAN) with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power, low-bandwidth needs, designed for small-scale projects which need wireless connection. Hence, Zigbee is a standard for low-power, low-data-rate, close-proximity wireless ad hoc networks.
