Wibree is a Digital Radio technology (intended to become an Open Standard of Wireless communications) designed for ultra low power consumption ( Button Cell Batteries ) within a short range (10 meters / 30 ft) based around low-cost Transceiver Microchip s in each device. HISTORY 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 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 ultra-low-power Bluetooth technology . TECHNICAL INFORMATION Wibree is designed to work side-by-side with and complement Bluetooth . It operates in 2.4 GHz ISM Band with Physical Layer Bit Rate of 1 Mbit/s . Main applications include devices such as Wrist Watch es, wireless Keyboard s, toys and sports sensors where low power consumption is a key design requirement. The technology was announced on 3 October 2006 by Nokia . Partners that currently license the technology and cooperate in defining the specification are Nordic Semiconductor , Broadcom Corporation , CSR and Epson . Other contributors are Suunto and Taiyo Yuden . Wibree is not designed to replace Bluetooth, but rather to complement the technology in supported devices. Wibree-enabled devices will be smaller and more energy-efficient than their Bluetooth counterparts. This is especially important in devices such as wristwatches, where Bluetooth models may be too large and heavy to be comfortable. Replacing Bluetooth with Wibree will make the devices closer in dimensions and weight to current standard wristwatches. Bob Iannucci, head of Nokia's Research Centre, claims the technology is up to ten times more efficient than Bluetooth. Reportedly, it will have an output power around -6 DBm . Nordic Semiconductor is aiming to sample Wibree chips during the second half of 2007 . REFERENCES |
