Introduction to ZigBee
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 personal area
networks. ZigBee devices are often used in mesh network form to transmit data over
longer distances, passing data through intermediate devices to reach more distant ones.
This allows ZigBee networks to be formed ad-hoc, with no centralized control or
high-power transmitter/receiver able to reach all of the devices. Any ZigBee device can
be tasked with running the network.
ZigBee is targeted at applications that require a low data rate, long battery life, and
secure networking. ZigBee has a defined rate of 250 kbit/s, best suited for periodic or
intermittent data or a single signal transmission from a sensor or input device.
Applications include wireless light switches, electrical meters with in-home-displays,
traffic management systems, and other consumer and industrial equipment that requires
short-range wireless transfer of data at relatively low rates. The technology defined by
the ZigBee specification is intended to be simpler and less expensive than other
WPANs.
