ZigBee
ZigBee is one of the most popular industry wireless mesh networking
standard for connecting sensors, instrumentation and control systems.
ZigBee, a specification for communication in a wireless personal area
network (WPAN), has been called the "Internet of things."
Theoretically, your ZigBee-enabled coffee maker can communicate
with your ZigBee-enabled toaster. ZigBee is an open, global, packet-
based protocol designed to provide an easy-to-use architecture for
secure, reliable, low power wireless networks. ZigBee and IEEE
802.15.4 are low data rate wireless networking standards that can
eliminate the costly and damage prone wiring in industrial control
applications. Flow or process control equipment can be place anywhere
and still communicate with the rest of the system. It can also be moved,
since the network doesn't care about the physical location of a sensor,
pump or valve
ZigBee
• Home and office automation
• Industrial automation
• Medical monitoring
• Low-power sensors
• HVAC control
• Plus many other control and monitoring uses

•ZigBee targets the application domain of low
power, low duty cycle and low data rate
requirement devices
ZigBee
• Low power consumption, simply implemented
• Users expect batteries to last many months to years
• Bluetooth has many different modes and states depending upon
your latency and power requirements such as sniff, park, hold,
active, etc.; ZigBee/IEEE 802.15.4 has active (transmit/receive)
or sleep
• Even mains powered equipment needs to be conscious of
energy.
• ZigBee devices will be more ecological than its predecessors
saving megawatts at it full deployment.
