  4. 4. NEED FOR BLUETOOTH A Cable Replacement Technology  It’s wireless.  It’s inexpensive.  You don’t have to think about it.
  5. 5. What Can Bluetooth Do For You? Landline Cable Replacement Data/Voice Access Points Personal Ad Hoc Networks

  8. 8. BLUETOOTH–MOUSE
  9. 9. Bluetooth -keyboard
  10. 10. And much more ……….
  11. 11. PICONETS • A Set Of BLUETOOTH Devices Sharing A Common Channel Is Called A PICONET
  12. 12. SCATTERNETS • Scatter nets are two or more independent and non-synchronized piconets that communicate with each other by making bridge nodes.
  13. 13. ARCHITECTURE STRUCTURE
  14. 14. COMPONENTS OF ARCHITECTURE • Radio Front End (RF) • Defines characteristics of RF, frequency bands, channel arrangements & receiver sensitivity level. • Logical Link Control & Adaptation Protocol (L2CAP) • For transporting bigger data products to higher layer. • Service Discovery Protocol (SDP) • To query and discover services supported by peer Bluetooth devices.
  15. 15. • Link Manager Protocol (LMP) • PICONET, master slave role assignments and link configuration. • Security configuration by device authentication using secret key. • RFCOMM • Provides transport capabilities for high level services.
  16. 16. CREATION OF A SCATTERNET • A Master or Slave can become Slave in another piconet by being paged by the Master in this other piconet.
  17. 17. NETWORK FORMATION AND CONTROL
  18. 18. : Future of Bluetooth : • Success of Bluetooth depends on how well it is integrated into consumer products • Consumers are more interested in applications than the technology • Bluetooth must be successfully integrated into consumer products • Must provide benefits for consumer Key Success Factors : • • • • Interoperability Mass Production at Low Cost Ease of Use End User Experience
  19. 19. ADVANTAGES OF BLUETOOTH • Bluetooth is used widely across countries and almost by everyone. • It has simple features. • It is free of charge and not added to our budget. • It has the ability to keep our information private. • It provides ranges of up to 100 meters.
  20. 20. DISADVANTAGES OF BLUETOOTH battery • More all day. phone power when Bluetooth is enable on the Throughout all device, when using Bluetooth internet, the • connection sometimes may run very slow so Bluetooth internet is not highly suggested for all cases. Infrared can data rates of up to M Bps, which • provides very haverates for data transfer,4while Bluetooth fast only offers 1 MBps
  21. 21. CONCLUSION a short range radio link wireless • Bluetooth isused to connect various device by technology a invisible link getting rid of wires. THINK OF • Last but not the least, WHENEVERthis is the WIRELESS,”THINK BLUETOOTH”, best way of communication.
