ZigBee Technology

The explosion in wireless technology has seen the emergence of many standards, especially in the industrial, scientific and medical (ISM) radio band. There have been a multitude of proprietary protocols for control applications, which bottlenecked interfacing. Need for a widely accepted standard for communication between sensors in low data rate wireless networks was felt. As an answer to this dilemma, many companies forged an alliance to create a standard which would be accepted worldwide. It was this Zigbee Alliance that created Zigbee. Bluetooth and Wi-Fi should not be confused with Zibgee. Both Bluetooth and Wi-Fi have been developed for communication of large amount of data with complex structure like the media files, software etc.  Zigbee on the other hand has been developed looking into the needs of communication of data with simple structure like the data from the sensors.

 

What is Zigbee

What is Zigbee and who all are involved?
Zigbee is a low power spin off of WiFi. It is a specification for small, low power radios based on IEEE 802.15.4 – 2003 Wireless Personal Area Networks standard. The specification was accepted and ratified by the Zigbee alliance in December 2004. Zigbee Alliance is a group of more than 300 companies including industry majors like Philips, Mitsubishi Electric, Epson, Atmel, Texas Instruments etc. which are committed towards developing and promoting this standard. The alliance is responsible for publishing and maintaining the ZIgbee specification and has updated it time and again after making it public for the first time in 2005. Most of the recent devices conform to the Zigbee 2007 specifications has two feature sets– Zigbee and Zigbee Pro. The manufacturers which are members of the Alliance provide software, hardware and reference designs to anyone who wants to build applications using Zigbee.
 
Many years ago, when Bluetooth technology was introduced, it was thought that Bluetooth would make WiFi redundant. But the two coexist quite well today, so do many other Wireless standards like WirelessHART and ISA100.11a. Then why would we need another WPAN standard like Zigbee? The answer is, the application focus of Zigbee Alliance - low cost and low power for energy efficient and cost effective intelligent devices. Moreover, Zigbee and Bluetooth have different application focus. Despite of all their similarities, and despite the fact that both are based on the IEEE 802.15 standards, the two are different in technology as well as scope. Bluetooth is made with mobile phones as its centre of universe enabling media transfer at rates in excess of 1 Mbps while Zigbee is built with emphasis on low data rate control system sensors featuring slower data of just 250 kbps.

Looks like the comparison chart of Zigbee and OSI is missing, though it finds reference in text.

Nice starting point to learn about ZigBee.

nice article

 

Zigbee a step for wireless projects...

Excellent write-up.

Nice article, can u give information about how to use ZigBee in OPNET

Nice artical,can you give information about how to build zigbee network  & its code?

 

nice articale and nice concept....

 

 

BLUETOOTH SUPPORTS 100 METERS ALSO

only 30 meters

Nice one....

good

Nice one artical
Nice one artical

good one

 

Why Aodv Only used in Zigbee?

I want to implement security of zigbee throgh their node initialization time can anyone help me in that?

If any one have idea then mail me on gopi.jayswal@gmail.com
