Overview of zigbee
Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication
protocols used to create personal area networks 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
low-power, low data rate, and close proximity (i.e., personal area) wireless ad hoc
The technology defined by the zigbee specification is intended to be simpler and less
expensive than other wireless personal area networks (WPANs), such as Bluetooth or Wi-Fi.
Applications include wireless light switches, electrical meters with in-home-displays,
traffic management systems, and other consumer and industrial equipment that requires
short-range low-rate wireless data transfer.
Its low power consumption limits transmission distances to 10–100 meters line-of-sight,
depending on power output and environmental characteristics.Zigbee devices can transmit
data over long distances by passing data through a mesh network of intermediate devices to
reach more distant ones. Zigbee is typically used in low data rate applications that
require long battery life and secure networking (zigbee networks are secured by 128 bit
symmetric encryption keys.) Zigbee has a defined rate of 250 kbit/s, best suited for
intermittent data transmissions from a sensor or input device.
Zigbee was conceived in 1998, standardized in 2003, and revised in 2006. The name refers to
the waggle dance of honey bees after their return to the beehive.
Applications of zigbee
Zigbee protocols are intended for embedded applications requiring low power consumption and
tolerating low data rates. Zig-Bee is not for situation with high mobility among nodes.
Hence, it is not suitable for tactical ad hoc radio networks in the battlefield, where high
data rate and high mobility is present and needed. The resulting network will use very
small amounts of power — individual devices must have a battery life of at least two years
to pass zigbee certification.
Typical application areas include:
Home Entertainment and Control — Home automation such as in QIVICON, smart
lighting,advanced temperature control, safety and security, movies and music
Wireless sensor networks — Starting with individual sensors like Telosb/Tmote and Iris
Medical data collection
Smoke and intruder warning
Remote wireless microphone configuration, in Shure Wireless Microphone Systems
