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.

7. Wibree supports star and star-bus network
topology

8. 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.

10. EFFECTIVE APPLICATION OF WIBREE
10

11. 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
11

12. Disadvantages:
• Data transmission is very slow, i.e. only
1Megabit per second
• Cannot be used in high bandwidth required
applications
12

13. 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.
