Pioneered by Philips Semiconductors, ZigBee is a low
data rate, two-way standard
for home automation and data networks. The standard originates from the
Working Group and provides a specification for up to 254
nodes including one
master, managed from a single
remote control. Real usage examples of ZigBee includes home
automation tasks such as turning lights on, turn up the heat, setting the home
security system, or starting the VCR. With ZigBee all these tasks can be done
from anywhere in the home at the touch of a button. ZigBee also allows for dial-in access via the
Internet for automation control.
The ZigBee standard uses small very low-power
devices to connect
together to form a
wireless control web. A ZigBee network is capable of
supporting up to 254 client nodes plus one full functional device (master).
ZigBee protocol is optimized for very long battery life measured in months to
years from inexpensive, off-the-shelf non-rechargeable batteries, and can
control lighting, air conditioning and heating, smoke and fire alarms, and other
security devices. The standard supports 2.4
GHz (worldwide), 868
and 915 MHz (Americas) unlicensed radio bands with range up to 75 meters.
