ZigBee Wireless Technology
ZigBee is a specification for a suite of high level communication protocols using small,
low-power digital radios based on the IEEE 802.15.4 standard for Wireless Personal Area
Networks (WPANs). The technology defined by the ZigBee specification is intended to be
simpler and less expensive than other WPANs, such as Bluetooth. ZigBee is targeted at
radio-frequency (RF) applications that require a low data rate, long battery life, and
secure networking and is designed for wireless controls and sensors.
ZigBee has two modes of operation: Active, also called WakeUp, and Sleep mode. In the
active mode the device is communicating with other nodes in the network. In sleep mode
the radio is turned off and the system enters power saving mode. The user can configure
the interval of both states.
ZigBee operates in the industrial, scientific and medical (ISM) radio bands; 868 MHz in
Europe, 915 MHz in the USA and Australia, and 2.4 GHz in most jurisdictions worldwide.
