Wibree is a new ultra low power radio technology that uses less power than Bluetooth to enable small, low-cost devices to connect wirelessly. It operates at 2.4GHz like Bluetooth but is 10 times more energy efficient. There will be two types of Wibree devices: stand-alone chips for small devices like heart rate monitors that need long battery life, and dual-mode Wibree-Bluetooth chips that allow Bluetooth devices to connect to tiny battery devices. Wibree will dramatically extend battery life and enable uses of wireless connectivity not previously possible for small devices relying on button cell batteries.

2. DEFINITION
Wibree is a radio technology which
consumes only a fraction of the power
compared to other such radio
technologies to achieve the Bluetooth
solutions.

3. What is Wibree?
power applications
 Enables smaller and less costly
implementationsto
achieve
Bluetooth
solutions.
 New radio technology for ultra low

4. Contd…
 Open industry initiative
First technology offering
connectivity between mobile devices
or personal computers and small,
button cell battery power devices like
watches,wireless keyboards,toys etc.

5. 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.

6. Wibree implementations:
There will be two types of
Wibree implementations Wibree stand-alone chip
 Wibree-Bluetooth dual-mode
chip

7. Wibree stand-alone chip:
For small devices (like heartrate monitors)
using only
short data messages and having
long battery life.
Examples: watches, sports and
wellness devices and human
interface devices (HID) such as
wireless keyboards.

8. Wibree-Bluetooth dual-mode chip:
 Designed for use in Bluetooth devices.
 This allows Bluetooth devices to connect
to a new range of tiny battery-powered
devices.
 Examples of devices are mobile phones
and personal computers.

9. Wibree and Bluetooth
 Bluetooth is a great technology and
brand, adopted worldwide
Bluetooth is widely used in mobile
devices like PC’s and phones, as well as in
wireless headsets. However, other products
relying on button cell batteries as a source
of power, e.g. watches, toys and human
interface devices, are not served effectively
by Bluetooth.

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

11. Wibree and Bluetooth
 Wibree is ultra low power technology
The maximum transmitted output power
of Bluetooth class
is 4dBm(~ 2.5 mW). The
total power consumption is much higher. The
output power of Wibree standard will be
around
-6dBm.
Each
manufacturer
determine its own transmit power.

12. Technologies comparison:

13. Advantages:
 Ultra-low power consumption
 Long battery life
 Use same frequency of Bluetooth
(2.4GHz)
 Small chip size
 10 times more energy efficient than
Bluetooth
 Inexpensive implementation

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

15. CONCLUSION
 From this we conclude that wibree will
dramatically extend the battery life time of
existing wireless devices.
 It’s up to 10 times more energy efficient than
Bluetooth.
 Today wibree is not only the nokia solution it is
being supported by the major Bluetooth chip
vendors including Cambridge silicon radio and
Broadcom. That means it will reside within the
chips in almost every brand of handset.
 In the end of 2009 there was over 100 millions
wibree enabled handsets in existence.
