Blue Tooth Technoloty
- 1. Good morning Welcome to the seminar
- 3. Bluetooth Simplifies Open Uses short data wireless range radio synchronisat protocol technology -ion
- 4. Bluetooth implementation Developed & licensed Uses by SIG Gaussian Frequency Uses shift keying frequency hopping spread spectrum
- 6. Bluetooth specification protocol stack
- 7. Bluetooth radio Frequency bands Transmitter characteristics Receiver characteristics Baseband error correction Hop selection Bluetooth security
- 8. 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
- 9. 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
- 10. 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
- 11. 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
- 12. Bluetooth profiles Describes implementation of user models Defines parameter ranges of each protocol Decreases the risk of interoperability problems
- 13. View of different sections of profiles
- 15. 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
- 16. 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
- 17. •Extended inquiry Bluetooth response •Secure simple pairing 2.1 Bluetooth • AMP • High speed 3.0 transport
- 18. Applications of Bluetooth A typical Bluetooth mobile A Bluetooth USB dongle phone headset
- 19. MOTOROLA –PORTABLE- BLUETOOTH car-kit-T305 Features- • Crisp & clear • Smooth execution • Fashionable & multi- faceted • Mini USB connector for easy charging • A Multi-function button
- 20. Advantages of Bluetooth Universally accepted economical Simplifies communication while driving
- 21. Best alternative of data transfer Instant PAN (personal area network) Standard protocol
- 22. Bluetooth v/s Wi-Fi -->uses wireless PAN -->simplifies discovery & setup of Services -->uses wireless LAN -->requires configuration to setup shared resources
- 23. Bluetooth security As it has many benefits, also susceptibility to denial of service attacks— Bluejacking Bluesnarfing bluebugging
- 24. 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
- 25. Disadvantages of Bluetooth Battery mileage Bluetooth internet
- 26. Thank you for your presence By, J.Pranaya Sujata Patnaik
