What is Zigbee?
Zigbee is a low-power, low data rate, and personal area wireless ad hoc network. It is the wireless language that everyday devices use to connect to one another.
ZigBee technology builds on IEEE standard 802.15.4 which defines the physical and MAC layers and used to create personal area networks.
This technology is developed by Zigbee alliance. Its physical range is 10 m to 20 m approximately.
It is a wireless networking standard and its main focus at remote applications such as sensor and control applications which is suitable for operation in harsh radio environments and in isolated locations.
This Technology is simpler and less expensive compare to Wireless Personal Area Network such as WiFi and Bluetooth.
It is specifically used for low-power low-bandwidth needs, designed for small scale projects which need wireless connection.
