  1. Bluetooth Technology

  2. Introduction • Definition • Why Bluetooth? • How Need Arise? • History • What Is Sig?

  3. Definition • Bluetooth Wireless Technology is a De facto standard, as well as a specification for small form factor, low cost, short range radio links between mobile PCs,mobile phones, and other portable devices.

  4. Overview Of Bluetooth • Technology Overview • Network Architecture

  5. Areas For Bluetooth Technology • Data And Voice Access Points: • Cable Replacement • Ad hoc Networking

  6. Network Architecture

  7. Bluetooth Protocol Stack • Protocols And Network Architecture • Bluetooth archi. Strategy

  8. Protocols & N/W Architecture

  9. Protocols

  10. Types Of Protocols • Bluetooth Core Protocols • Cable Replacement Protocol • Telephony Protocols • Adopted Protocols

  11. 1)Bluetooth Core Protocol • Base Band • Link Manager Protocol • Service Discovery Protocol • L2CAP Protocol

  12. 2)Cable Replacement Protocol • RFCOMM (Redio Frequency Communications)

  13. 3)Telephony Protocols • TCS-BIN Bit by Bit Transfer Protocol

  14. 4) Adopted Protocols • WAP: Wireless Application Protocol • PPP: Point To Point • TCP/IP • OBEX Protocol • HTTP

  15. Fns Of Link Management : • 1) Sending Data • 2) Link Address Inquiries • 3) Connection Set Up • 4) Authentication • 5) Link Mode Set Up • 6) Setting a Device In Sniff Mode • 7) Setting a link device on hold

  16. Link Types & Packet Types • Synchronous Connection Oriented • Asynchronous Connectionless Type

  17. Error Correction • Forward Error Correction • Automatic Repeat Request

  18. Forward Error Correction • Reduces The No Of Transmission • It contains valueable link informaton & bit errors

  19. Automatic Repeat Correction • Error Check & Cyclic Redundancy check must be maintained or negative acknolodge is returned

  20. Authontication, Privacy, Sequrity • Service Level Sequrity • Link Level Sequrity • Encryption Technique For Privacy Of Connection

  21. Bluetooth Usage Models • File Transfer • Internet Bridge • LAN Access • Synchronization • Three-in-One Phone

  22. Competting Techniques • IrDA(4 mbps) • IEEE 802.11 • Ultra Wideband Radio • Home RF(DECT)(144 kbps)

  23. IrDA • IrDA Is a Infrared Interface Standard • Problems: • It Is Limited To Point To Point Connections • Its need For Line Of Sight

  24. IEEE 802.11 • Higher Transmission Capacity • Bluetooth H/W considerable Smaller • Bluetooth Is 10 times smaller

  25. Ultra-Wideband Radio • Concept Of Radar • Payloads up to 1.25 Mbps • Range Up To 70 Metres • Power Consumption up to 0.5 mW

  26. Home RF • New Radio Technology • It is a DECT Concept • Frequency Of 2.4Ghz

  27. Application Of Bluetooth • In Vending Machine • E-mail Delivery to The PC • The E-Wallet • The Underground Train • The Bluetooth Headset

  28. Advantages • Minimal Hardware Dimensions • Low Price • Low Power Consumption
