Wibree ppt
- 1. www.oeclib.in Submitted By: Odisha ElectronicControl Library Seminar On Wibree
- 2. • Various WirelessTechnologies • 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 thefirst 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. 4
- 5. Currently available standardizedlocal connectivity technologies are not optimized for ultra low power applications. 5
- 6. • Technology comingunder 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: • Therewill be two types of Wibree implementations • Wibree stand-alone chip • Wibree-Bluetooth dual-mode chip 7
- 8. Wibree stand-alone chip: Usedwith 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. 8
- 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 9
- 11. There are twodifferent 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 anddual 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 12

- 17. EFFECTIVE APPLICATION OFWIBREE 17
- 18. Advantages • Ultra-low powerconsumption • Long battery life • Small chip size • 10 times more energy efficient than Bluetooth • Inexpensive implementation • Easily integrated with Bluetooth solutions 18
- 19. Disadvantages: • Data transmissionis very slow, i.e. only 1Megabit per second • Cannot be used in high bandwidth required applications 19
- 20. Future With WIBREE µBlueis 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 ofthese 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. 21
