The document discusses Wibree, a wireless technology introduced by Nokia that allows for connectivity between mobile devices/PCs and small battery-powered devices. Wibree uses very low power (10x less than Bluetooth) and is optimized for applications requiring years of battery life on small batteries. It operates at 2.4GHz, supports star and star-bus network topologies, and will be implemented via standalone Wibree chips or chips with dual Wibree/Bluetooth functionality. Potential applications include wireless keyboards, toys, health/fitness sensors, and other small devices.

2. • Various Wireless Technologies
• What is Wibree?
• Specification
• Why is Wibree needed?
• Wibree implementations
• Wibree and Bluetooth comparison
• Applications
• Advantages and Disadvantages
2

3. • Wi-Fi, Wi-max, Zigbee, Bluetooth…….
• These connect to large devices like mobile
phones or personal computers. No other
existing wireless technologies will connect with
small button cell battery devices so effectively.
• Nokia introduced the new connectivity
technology WIBREE
• Wibree is also known as Bluetooth Low
Energy Technology
3

4. 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 & health care sensors.

5. Currently available standardized local
connectivity technologies are not optimized for
ultra low power applications.

6. • Technology coming under IEEE 802.15.4
STANDARD
• The 2.4GHz frequency connectivity technology,
offering low power usage.
• Wibree’s design goal of 1-2 years on a single
battery.
• Wibree is “up to 10 times more energy efficient
than Bluetooth”, putting Wibree around 10mW.
6

7. Wibree implementations:
• There will be two types of Wibree
implementations
• Wibree stand-alone chip
• Wibree-Bluetooth dual-mode chip
7

8. Wibree stand-alone chip:
Used with applications which require
extremely low power consumption, small size, low
cost and where only small quantities of data are
transferred.
An ideal solution for small devices (like heart-
rate monitors) that use only short data messages
and must have long battery life.

9. Wibree-Bluetooth dual-mode chip:
• Designed for Bluetooth devices
• Integrating with Bluetooth chip using current
Bluetooth peripherals
• Additional tiny power cell (EG: CR2430)
• Mainly integrated in mobile devices & personal
computers

11. There are two different cases for the
network topologies :
 single and dual mode topology
 single mode only topology
Wibree supports star and star-bus network
topology
11

12.  Single and dual mode topology
- dual mode devices act as hubs and single
mode devices act as nodes
- the connection between hub & node is a
BT low energy technology
 Single mode topology
one of the single mode devices acts as hub

14. Wibree and Bluetooth
• The maximum transmitted output power of
Bluetooth class 2 is 2.5 mW. The total power
consumption is much higher.
• The output power of Wibree standard will be
around 0.25mW. Each manufacturer will
determine its own transmit power.

17. EFFECTIVE APPLICATION OF WIBREE
17

18. Advantages
• Ultra-low power consumption
• Long battery life
• Small chip size
• 10 times more energy efficient than Bluetooth
• Inexpensive implementation
• Easily integrated with Bluetooth solutions
18

19. Disadvantages:
• Data transmission is very slow, i.e. only
1Megabit per second
• Cannot be used in high bandwidth required
applications

20. Future With WIBREE
µBlue is the upcoming Bluetooth low energy
solution range from Nordic Semiconductor. It will
bring Bluetooth wireless connectivity to portable
devices running on small but standard coin cell
(watch) batteries and support battery lifetimes from
months to years, depending on the application
20

21. Taking all of these factors together, Wibree
has the potential to transform consumer devices.
It will solve the technology and monitoring
issues that are currently hindering the adoption
of wireless healthcare services and enable a whole
new generation of lifestyle, monitoring and safety
products.
