Wibree at a glance
Initiated and headed by Nokia
Initial participants includes CSR, Broadcom, Nordic, Epson, Suunto and
Tayo Yuden
Merged with Bluetooth SIG in 2007
Many more companies now participating through the Bluetooth SIG

Purpose of Wibree
No existing open standard offers true ultra low power operation

No standard has been optimized for low power consumption for
low duty cycle applications

Several years of battery lifetime on a coin cell battery

6 to 12 months battery lifetime on AA or AAA batteries
Proprietary technologies dominates for the ultra low power applications


Examples:
•
2.4GHz mouse and keyboard
•
Sports watches and sensors
Lack of interoperability limits wide adoption and possible
applications (for example in mobile phones)

Key Concepts
Ultra low power consumption

Wibree is optimized for power consumption, specifically for low duty cycle
applications (3.75ms to 4s poll intervals)
Cost efficient integration with Bluetooth™

Wibree offers cost efficient integration with Bluetooth™ enabling a small
price delta for a “dual mode” Wibree + Bluetooth ™ chip
Stand alone and dual mode Wibree chips

Stand alone Wibree chip can communicate with other stand alone Wibree
chips and/or dual mode chips

A dual mode chip can communicate with other stand alone or dual mode
Wibree chips in addition to other Bluetooth™ chips
Complementing Bluetooth™ and other short-range wireless standards

Wibree complements Bluetooth™ for ultra low power connectivity

Standardization Work Related to Wibree / ULP Bluetooth
It is not sufficient to standardize the radio protocol, which is only the transport layer.
One will also have to precisely define the data types and the meaning of the data being
transported.
IEEE 11073 Personal Health Data Work Group

ISO / IEEE 11073-20601
A common framework for an abstract model of personal health data available in transport
independent transfer syntax required to establish logical connections between systems,
provide presentation capabilities and services needed to perform communication tasks.
