1.WIBREE
2.INTRODUCTION
It is a digital radio technology designed for ultra low power consumption (in batteries of devices) within a short range (10 meters),small size & lost cost applications.
Some of the technologies now in use are Wi-Fi, Wi-max, Zigbee , Bluetooth.Out of which Bluetooth is most popular. These technologies are widely used to connect the large devices like mobile phones or personal computers.

3.No other existing wireless technologies will connect with small button cell battery devices so effectively. So the Nokia introduced the new radio technology called Wibree.
4.What is Wibree?
New radio technology for ultra low power applications.
Developed by NOKIA.
Wibree is the first open technology offering connectivity between mobile devices or personal computers, and small, button cell battery power devices such as watches, wireless keyboards, toys and sports & health care sensors.

5.Wibree can be seen as Bluetooth enhancer in many ways rather than a bluetooth killer (Wibree is going to compliment bluetooth and not to replace it).
It operates in 2.4 GHz band with physical layer bit rate of 1 Mbit/s.
NOKIA introduced this short range wireless technology in October 2006.

6.Why is Wibree needed?
Ultra low power cannot be achieved with existing open standards
Currently available standardized local connectivity technologies are not optimized for ultra low power applications.
7.Wibree implementations:
There will be two types of Wibree implementations-
Wibree stand-alone chip
Wibree-Bluetooth dual-mode chip
8.Wibree stand-alone chip:
This chip is used for design of applications which –
Require extremely low power consumption.
Small size
Low cost
Where only small quantity of data is transferred in small devices which have much long battery time. Eg: wireless keyboard,watches etc.
9.Wibree-Bluetooth dual-mode chip:
This chip is designed for used in –
Bluetooth devices which connect to a new range of tiny battery powered devices.
Eg :
Mobile phones
Personal Computers.
10.Wibree and Bluetooth
Bluetooth is a wireless technology widely used in –
Mobile devices like PC’s and Phones.
Wireless Headsets.
Products relying on button cell batteries as a source of power Eg:
Watches
Human interface devices . These devices are not served by bluetooth .

11.Similarities
Wibree and Bluetooth use the 2.45 GHz band to transfer data and have a 1 Mbps transfer rate and a rage of about 10 meters (m).
In Wibree-Bluetooth dual-mode they share the components like antenna.

12.Implementation schedule
13.Low bandwidth technologies comparison:
14.Advantages:
Long battery life
Use same frequency of Bluetooth (2.4GHz)
Small chip size
10 times more energy efficient than Bluetooth
Inexpensive implementation
Easily integrated with Bluetooth solutions
Ultra low power consumption.

15.Disadvantage:
Data transmission is very slow, i.e. only 1Megabit per second
Cannot be used in high bandwidth required applications

16.SUMMARY:
As the First announcement about Wibree was only made in October 2006, and few details have been defined, it will take some time for the work to be completed. Wibree forum merges with the Bluetooth SIG and Wibree becomes part of the Bluetooth specification as an ultra low power Bluetooth technology. Yet despite this it is anticipated that the first release of the specification will be available by the end of second quarter of 2007 or in the first quarter of 2008 and devices late in the year. It will be interesting to see how Wibree is accepted by the market and whether it takes off in the way Nokia hopes.
