  1. Interconncection Protocols By Berk USTUNDAG Istanbul Technical University RF Interconnection 7.1 Blue Tooth 7.2 NMEA Protocol

  2. Bluetooth Named after Harold Bluetooth, King of Denmark (0952-0995 A.D.) Ericsson a Scandanavian company and founding member said to have suggested the code name Technology allows for the connection of one device to another using a universal short-wave radio link

  3. Bluetooth SIG Special Interest Group formed by leaders in telecommunications and computing industries Founded in1998 by: Ericsson, IBM, Intel, Nokia, Toshiba, 3Com, Lucent, Microsoft and Motorola Developed a royalty-free, open specification Now has 1883 adopter member companies

  4. Adopter Benefits Right to use the specification for product and software development Access to pre-release spec and documents Participation in an online forum

  5. Qualification Program Guarantees that Bluetooth products are “wireless made easy” The qualification is brand approval, not type approval Protects the Bluetooth brand by ensuring interoperability Grants manufacturers the right to use the Bluetooth trademark

  6. How Does Bluetooth Work? Short Range RF at 2.45 GHZ called ISM Uses Quick Frequency Hoping Packet Switched Protocol Transceiver has a unique 48 Bit Address Using IEEE 802 Standard Piconet Network Structure

  7. How Does Bluetooth Works?(cont.)

  8. How Does Bluetooth Works?(cont.) • More than one Piconet is a Scatternet • Up to Eight Devices Allowed in a Piconet • Each Piconet is Identified by a Different Frequency Hopping Sequence • Connections can be made up to 10 meters or extended up to 100 meters • Power Consumption is .3mA • Supports Half-Duplex or Full-Duplex • Time Division Duplex Scheme is used for Full-Duplex

  9. How Does Bluetooth Works?(cont.)

  10. How Does Bluetooth Works?(cont.)

  11. Competing Technologies • IrDA- Infrared Data Association • Narrow Angle Infrared Ad-Hoc Data Standard • Range is 0-1 Meter at 9600bps to 4Mbps • HomeRF • 2.4 GHz ISM • Uses Swap a Derivative of IEEE 802 Standard • SWAP( Shared Wireless Access Protocol)

  12. Bluetooth Protocol Stack • Interoperability • Different Applications can run over Different Protocol Stacks • Open Interface • Protocol Divided Into 4 layers

  13. Bluetooth Protocol Stack

  14. Bluetooth Protocol Stack • Host Controller Interface(HCI)- Command Interface to Baseband Controller, Link Mgr, & Access to Hardware • Bluetooth Core Protocols • Baseband-pluse link Layer Provide RF link to Create Piconets • Audio-Goes Directly to Baseband Layer • Link Manager Protocol(LMP)- Link setup between Bluetooth Devices • Logical Link Control and Adaptation Protocol(L2CAP)-Adapts Upper Layer Protocols over the Baseband • Service Discovery Protocol- Provides Device Information and Characteristics

  15. Bluetooth Protocol Stack • Cable Replacement Protocol • RFCOMM- Serial Line Replacement Protocol; Emulates RS-232 • Telephony Control Protocols • Telephony Control Binary(TCS)- Defines Call Control Signaling for Speech and Data • Telephony Control-AT Commands- Provides Interface capabilities with Mobile Phones, Modems , Faxes

  16. Bluetooth Protocol Stack • Adopted Protocols • PPP(Point-To-Point Protocol) • TCP/UDP/IP • OBEX-Session Protocol for IrDA(Infrared Data Association) • Contents Fromat(e.g. vCard, vCalendar) • WAP-Wireless Application Protocol

  17. Bluetooth Protocol Stack

  18. Bluetooth Security • Supports Unidirectional or Mutual Encryption based on a Secret Link key Shared Between Two Devices • Security Defined In 3 modes: • Mode1- No Security • Mode 2 - Service Level Security: Not Established Before Channel is Established at L2CAP • Mode 3 - Link Level Security: Device Initiates Security Before LMP Link is Setup

  19. Bluetooth Security • Devices and Services can be Set for Different Levels of Security • Two Trust Levels are Set for Devices • Trusted Device: Fixed Relationship and Unrestricted Access to All Services • Untrusted: No Permanent relationship and Restricted Services

  20. Bluetooth Security • 3 Levels of Service Access • Require Authorization and Authenication • Require Authentication Only • Default Security for Legacy Applications

  21. Bluetooth Security

  22. Potential Bluetooth Markets

  23. Target Markets • The first wave 1. PC, Notebooks 2. Organizers & Palm Computers 3. Headsets 4. Cellular/PCS 5. Cordless phones 6. Automotive cellular 7. Digital cameras 8. PBX

  24. Target Markets • The second wave 1. Printers 2. Photo printers 3. Fax machines 4. Industrial, musical and vertical industries products

  25. Target Markets • The third wave 1. Home networking 2. Office networks 3. Video projectors 4. Set top boxes

  26. Market Forecast for Bluetooth Products • Telecommunications Market • Computing Market • Digital Still Cameras Market • Output Equipment Market • Accessories Market • Industrial, Medical & Vertical Markets • Home Networking Market

  27. Market Forecast

  28. Market Forecast Summary • Telecommunications market is the largest • The market growth relies on the cost • By 2002, the cost is predicted to $10 and the bluetooth-enabled products will have $126 million sales with the highest growth rate • In 2005, market sales will reach $671 million
