Blue Tooth Technoloty

  1. 1. Good morning Welcome to the seminar
  2. 2. Seminar on Bluetooth
  3. 3. Bluetooth Simplifies Open Uses short data wireless range radio synchronisat protocol technology -ion
  4. 4. Bluetooth implementation Developed & licensed Uses by SIG Gaussian Frequency Uses shift keying frequency hopping spread spectrum
  5. 5. Bluetooth specification protocol stack
  6. 6. Bluetooth radio  Frequency bands Transmitter characteristics Receiver characteristics Baseband  error correction Hop selection Bluetooth security
  7. 7. LMP Used by link managers Mainly made up of PDU’s HCI Acts as a command interface Communicates the host stack with the host controller
  8. 8. L2CAP Provides connection oriented & connectionless data services Two link types -SCO -ACl RFCOMM Creates a virtual serial data stream Acts as a transport layer Emulation of serial ports
  9. 9. SDP Uses a request/response model Discovers services provided by other Bluetooth devices AVCTP Audio/visual control transport protocol AVDTP Audio/visual data transport protocol
  10. 10. TCS-BIN Telephony control protocol-binary bit oriented protocol ADOPTED PROTOCOLS It includes- ppp point-to-point protocol Tcp/ip/udp foundation protocol Obex object exchange protocol wae wireless application environment Wap wireless application protocol
  11. 11. Bluetooth profiles Describes implementation of user models Defines parameter ranges of each protocol Decreases the risk of interoperability problems
  12. 12. View of different sections of profiles
  13. 13. How Bluetooth works
  14. 14. Modes of operation piconet connection between 2 or more devices each piconet is identified by a different FHS follows a master slave mechanism Scatternet connection of different piconets
  15. 15. Different versions of Bluetooth • Supports non- • Required encrypted mandatory channels BD_ADDR Bluetooth Bluetooth 1.0 & 1.0B 1.1 Bluetooth Bluetooth 2.0 1.2 • EDR • AFH, eSCO • Low power • High consumption transmission speed
  16. 16. •Extended inquiry Bluetooth response •Secure simple pairing 2.1 Bluetooth • AMP • High speed 3.0 transport
  17. 17. Applications of Bluetooth A typical Bluetooth mobile A Bluetooth USB dongle phone headset
  18. 18. MOTOROLA –PORTABLE- BLUETOOTH car-kit-T305 Features- • Crisp & clear • Smooth execution • Fashionable & multi- faceted • Mini USB connector for easy charging • A Multi-function button
  19. 19. Advantages of Bluetooth Universally accepted economical Simplifies communication while driving
  20. 20. Best alternative of data transfer Instant PAN (personal area network) Standard protocol
  21. 21. Bluetooth v/s Wi-Fi -->uses wireless PAN -->simplifies discovery & setup of Services -->uses wireless LAN -->requires configuration to setup shared resources
  22. 22. Bluetooth security As it has many benefits, also susceptibility to denial of service attacks— Bluejacking Bluesnarfing bluebugging
  23. 23. To protect data-- Many software patches available for older Bluetooth phones Turn to non-discoverable mode when not in use Never pair with unknown devices or In public places
  24. 24. Disadvantages of Bluetooth Battery mileage Bluetooth internet
