Wibree is a new low power, low cost , inter operable radio technology for small devices.

2. What is WIBREE?
 Wibree is a new low power, low cost , interoperable
radio technology for small devices.
 Wibree complements other local connectivity
technologies, consuming only a fraction of the
power, enabling small, inexpensive
implementations as well as easy integration with
Bluetooth solutions.

3.  Wibree is the first open technology offering
connectivity between mobile devices or personal
computers, and small, button cell battery power
devices.
 By extending the role, mobile devices can play in
consumers' lives, this technology increases the growth
potential in these market segments

4. Wibree fullfills the need for a radio
technology that:
 Allows communication between small button-cell
battery devices and Bluetooth devices.
 Forms a minimal cost and size addition to Bluetooth
devices such as mobile phones and PCs.
 Creates smaller and lower cost options for small
button-cell battery devices.

5. Examples:
(1).Mouse communicating with computer using Wibree

6. (2).Here the keyboard is communicating with cell phone&
the watch displays the heart beat and the stress applied to the bat.

7. Need for Wibree
 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

8. Key Features
 Very low power consumption
 Forms a minimal cost and size
 Allows communication between small battery-
powered devices
 Cost efficient implementation with the present
Bluetooth modules

9. Types of Wibree chips
There are two types:
1. Stand alone mode Wibree
2. Dual mode Wibree

10. Stand alone mode Wibree :
 Stand alone Wibree chip can communicate with other
stand alone Wibree chips and/or dual mode chips.

11. Wibree
Example for stand alone mode:

12. Dual mode Wibree
 A dual mode chip can communicate with other stand
alone or dual mode Wibree chips in addition to other
Bluetooth chips
Wibree

13. Wibree versus Bluetooth:
 The device that is compatible with the
bluetooth can communocate with the other
device within 100meters of range.
 The speed of the data transfer is upto 5Mbps.
 The power consumption is higher when
compared to Wibree.
 It is not suitable for smaller devices.
Bluetooth:

14. Wibree:
 It can communicate with the other device within
10meters of range.
 The power consumption is very low.
 The speed of data transfer is upto1mbps.
 It is suitable for smaller devices.

16. Bluetooth:
 It is the primary channel of the protocol.
 0.400-2.4835 GHz is the frequency range at which it
operates.
 5 Mbps is the speed.
 It can communicates with the other device upto
100meters.
RF channel:

17. Link controller: It contains master .
 Master just establishes connection with the
slaves.

18. Link manage protocol:
 The Link Manager Protocol (LMP) is used to
control and negotiate all aspects of the operation of
the Bluetooth connection between two devices.

19. Physical Layer:
 Up to 10m range.
 1 Mega bit/sec air data rate
 RF Antenna which will operate at the 2.4 GHz
can work with the help of the Bluetooth antenna
Wibree:

20. Link Layer
 Low power idle mode
 Scan service
 Connection set-up service
 Data exchange service
 Traffic scheduling services

21. Wibree Profiles
 Watch profile
 Human Interface Device (HID) profile
 Sensor profile

22. How power is saved in Wibree
 Wibree is aiming to produce a radio that can
transmit a small packet of data approximately
every second
 This low power drain is achieved by designing a
radio and protocol that lets the radio stay asleep
for most of its life. It can wake up quickly, when it
will broadcast its requirement to transfer data on a
number of advertising channels across the
spectrum.

23. •The Bluetooth Special Interest Group (SIG), the more
than 8,000-company strong trade association
responsible for advancing Bluetooth wireless
technology, joined Nokia today in announcing that
Wibree, the Nokia developed low power wireless
technology, will be contributed to the Bluetooth SIG.

24. The new opportunity for network operators and
service providers
 One of the most important features about Wibree is that it
will quickly become embedded into a wide range of mobile
phones. That allows the phone to act as a gateway for
information, transmitting it back over the network to an
Internet based monitoring service.
 data throughputs involved will be small, so the
transmission costs will be low and will not swamp the
networks capacity thus opening a wide range of
opportunities to a large number of fields.

25. Conclusion
 Taking all of these factors together, Wibree has the
potential to transform consumer devices.
 Today Wibree is a Nokia solution. However, the major
Bluetooth chip vendors including Cambridge Silicon Radio
and Broadcom are supporting it. That means it will reside
within the chips in almost every brand of handset.
 Wibree is placed to own the wireless healthcare market.
