Title: Bluetooth Wireless Protocol


1
Bluetooth Wireless Protocol
  • ECOM 540
  • 7/17/00
  • Project Team
  • Shu-Chun Ho, Tom Kartheiser, Gwen Zahrobsky,
    Frank Zuccarelli

2
Overview
  • Bluetooth SIG
  • Wireless Technology
  • Wireless Market
  • Bluetooth Products

3
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

4
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

5
Adopter Benefits
  • Right to use the specification for product and
    software development
  • Access to pre-release spec and documents
  • Participation in an online forum

6
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

7
Product Qualification Process
8
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

9
How Does Bluetooth Works?(cont.)
10
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 fo Full-Duplex

13
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)

14
Bluetooth Protocol Stack
  • Interoperability
  • Different Applications can run over Different
    Protocol Stacks
  • Open Interface
  • Protocol Divided Into 4 layers

15
Bluetooth Protocol Stack
16
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

17
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

18
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

19
Bluetooth Protocol Stack

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

21
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

22
Bluetooth Security
  • 3 Levels of Service Access
  • Require Authorization and Authenication
  • Require Authentication Only
  • Default Security for Legacy Applications
