 Welcome to our
guide to "Wibree" - announced by Nokia in 2006.

Wibree radio technology
complements other local connectivity technologies, consuming only a
fraction of the power compared to other such radio technologies,
enabling smaller and less costly implementations and being easy to
integrate with Bluetooth solutions....
Wibree Technology Wibree is
the first wireless technology to solve the following needs in a
single solution.
- Ultra low peak, average & idle mode power consumption
- Ultra low cost & small size for accessories & human
interface devices
- Minimal cost & size addition to mobile phones & PCs
- Global, intuitive & secure multi-vendor interoperability
Wibree radio
specification Wibree radio specification enables dual-mode
implementations to reuse Bluetooth RF part but also to guarantee
ultra low power consumption for devices with embedded stand-alone
implementation of the Wibree specification. Wibree operates in 2.4
GHz ISM band with physical layer bit rate of 1 Mbps and provides
link distance of 5-10 meters.
Wibree link layer
specification Wibree link layer provides ultra low power idle
mode operation, simple device discovery and reliable
point-to-multipoint data transfer with advanced power-save and
encryption functionalities. The link layer provides means to
schedule Wibree traffic in between Bluetooth transmissions.
Partners Broadcom
Corporation, CSR, Epson and Nordic Semiconductor have licensed the
Wibree technology for commercial chip implementation and Suunto and
Taiyo Yuden are contributing to the interoperability specification
in their respective areas of expertise (2006). |

An introduction to
Wibree (PDF, 2006) Following an unexpected launch, Wibree has
been subjected to an initial flurry of misunderstanding and then has
been largely ignored. The reality is that it is poised to become the
fastest growing wireless standard ever. Its symbiotic relationship
with Bluetooth will open up massive opportunities for network
operators to deploy new consumer based services, kick-starting the
C2M Consumer to Machine market. This White Paper explains the
reality and the opportunities. |

Nokia
introduces Wibree technology as open industry initiative (October
2006) A unique radio technology extending local connectivity to
small devices. Nokia today introduced Wibree technology as an open
industry initiative extending local connectivity to small devices.
This new radio technology developed by Nokia Research Center
complements other local connectivity technologies, consuming only a
fraction of the power compared to other such radio technologies,
enabling smaller and less costly implementations and being easy to
integrate with Bluetooth solutions. 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 sensors. By extending
the role mobile devices can play in consumers' lives, this
technology increases the growth potential in these market segments.
Technical details: Wibree technology complements close range
communication with Bluetooth like performance within 0-10 m range
and data rate of 1 Mbps. Wibree is optimized for applications
requiring extremely low power consumption, small size and low cost.
Wibree is implemented either as stand-alone chip or as
Bluetooth-Wibree dual-mode chip. The small devices like watches and
sports sensors will be based on stand-alone chip whereas Bluetooth
devices will take benefit of the dual-mode solution, extending
Bluetooth device connectivity to new range of smallest devices. |

Why,
why, Wibree? (10/06) Is Nokia's new wireless standard really
mature enough? Wibree is a low-power option for Bluetooth, at least
that's how it's being pitched by Nokia. But in reality there seems
little similarity between the two. Wibree will use the same antenna
and frequency (the increasingly crowded 2.4GHz band), but other than
that the work has been to ensure that it will happily co-exist with
Bluetooth, not be compatible with it. The Bluetooth SIG said it has
been in discussions with Nokia about incorporating Wibree into its
standard, but that discussions were still proceeding - which is
unsurprising given the lack of details yet available on Wibree.
Bluetooth works because it incorporates a couple of really useful
technologies, which Wibree will struggle to emulate. |
