Abstract:
These connect to large devices like mobile phones or personal computers. No other existing wireless technologies will connect with small button cell battery devices so effectively. “Nokia introduced the new connectivity technology WIBREE”.
A Technology coming under IEEE 802.15.4 Standard called Wibree technology. Wibree is a short-range wireless protocol optimized for low power consumption. Developed primarily by Nokia, the company has submitted Wibree as an open standard to promote adoption and interoperability. Wibree is intended to compliment Bluetooth communications in certain PAN applications where small, lightweight design makes standard Bluetooth communication unsuitable or difficult. For instance, Bluetooth-enabled wristwatches require relatively large transmitters and batteries, making the devices heavy and uncomfortable. Wibree-enabled wristwatches can use smaller transmitters and smaller batteries, increasing user comfort and reducing fatigue while extending battery life.
Introduction:
Wibree is an innovative digital radio technology that can soon become a benchmark for the open wireless communication. Working almost equivalent to the Bluetooth technology, this modern technology functions within an ISM band of 2.4 GHz and amid a physical layer bit rate of 1 Mbps.
Widely used in may appliances like the wrist watches, wireless keyboards, toys and sports sensors due to its key feature of very low consumption of power within the prescribed ranges of 10 meters or 30 feet using the low cost transceiver microchips, it can generate an output power ofm-6 dBm.
Conceived by the Nokia Company in 10-03-2006, it is today licensed and further researched by some of the major corporates that includes Nordic Semiconductor, Broadcom Corporation, CSR, Epson, Suunto and Taiyo Yuden.
According to Bob lannucci, the head of Nokia s research centre, this groundbreaking technology that is 10 times more capable than the Bluetooth technology will soon replace it.

Already the corporate giant Nordic Semiconductor is working on the technology so as to bring out the model chips by the mid of 2007.
Evolution of WIBREE:
In 2001, Nokia researchers determined that there were various scenarios that contemporary wireless technologies did not address. To address the problem, Nokia Research Center started the development of a wireless technology adapted from the Bluetooth standard which would provide lower power usage and price while minimizing difference between Bluetooth and the new technology. The results were published in 2004 using the name Bluetooth Low End Extension. After further development with partners, e.g., within EU FP6 project MIMOSA, the technology was released to public in October 2006 with brand name Wibree. After negotiations with Bluetooth SIG members, in June 2007, an agreement was reached to include Wibree in future Bluetooth specification as an Bluetooth ultra-low-power technology, now known as Bluetooth low energy technology.
The Wibree standard:
The Wibree is a wireless technology. It’s open standard based on the Bluetooth. The Wibree technology must have the same debit (1Mb/s) than the Bluetooth technology. All the specifications of Bluetooth and Wibree technologies are the same expect the power consumption of Wibree must be ten time inferior to the power consumption of Bluetooth. The frequency band is between 2.4 GHz and 2.4835 GHz. The channel bandwidth is 2 MHz. The modulation is GFSK (Gaussian frequency shift keying). This technology doesn’t replace the Bluetooth technology. The Wibree will use in the new type of object like sport sensors or toys.
What Wibree does:
Wibree’s main application is to provide an ultra low power radio within the 2.4GHz band. Low power is always determined in large part by the application – the longer a device is active, and the more data it transmits, the shorter its battery life will be.
