“ZIGBEE WIRELESS SYSTEM
[attachment=66754]
INTRODUCTION
●ZigBee is a wireless network protocol specifically designed for low data rate sensors
and control networks.
●There are a number of applications that can benefit from the ZigBee protocol: building
automation networks, home security systems, industrial control networks, remote
metering and PC peripherals are some of the many possible applications.
●Compared to other wireless protocols, the ZigBee wireless protocol offers low
complexity, reduced resource requirements and most importantly, a standard set of
specifications.
● It also offers three frequency bands of operation along with a number of network
configurations and optional security capability.
●If you are currently exploring alternatives to your existing control network technologies,
such as RS-422, RS-485 or proprietary wireless protocol, the ZigBee protocol could be
the solution you need.
●This application note is specifically designed to assist you in adopting the ZigBee
protocol for your application.
●ZigBee is expected to provide low cost and low power connectivity for equipment that
needs battery life as long as several months to several years but does not require data
transfer rates as high as those enabled by Bluetooth. In addition, ZigBee can be
implemented in mesh networks larger than is possible with Bluetooth.
ZIGBEE PROTOCOL OVERVIEW
●ZigBee is a standard wireless network protocol designed for low data rate control
networks.
● It is layered on top of the IEEE 802.15.4 specification and provides a standard
methodology for functions, including network formation, messaging and device
discovery.
NETWORK CONFIGURATIONS
●A ZigBee protocol wireless network may assume many types of configurations. In all
network configurations, there are at least two main components:
• Coordinator node
• End device
●The ZigBee protocol coordinator is a special variant of a Full Function Device (FFD)
that implements a larger set of ZigBee protocol services. An end device may be an FFD
or a Reduced Function Device (RFD).
●An RFD is the smallest and simplest ZigBee protocol node. It implements only a
minimal set of ZigBee protocol services.
● A third and optional component, the ZigBee protocol router, is present in some network
configurations.
FUTURE ENHANCEMENT
●Futurists are sure to hold ZigBee up and say, "See, I told you so".
●The ZigBee Alliance is nearly 200 strong and growing, with more OEM's signing up.
This means that more and more products and even later, all devices and their controls will
be based on this standard.
●Since Wireless personal Area Networking applies not only to household devices, but
also to individualised office automation applications, ZigBee is here to stay. It is more
than likely the basis of future home-networking solutions
0.CONCLUSION
ZIGBEE and underlying IEEE 802.15.4 communication technology could form
the basis of FUTURE WIRELESS SENSORS, OFFERING
