Introduction

1.1 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.
