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

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.

Overview Of Bluetooth Technology Overview Network Architecture

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

Bluetooth Protocol Stack Protocols And Network Architecture Bluetooth archi. Strategy

Protocols & N/W Architecture

Abbreviations Used OBEX OBject Exchange Protocol WAP Web Application Protocol UDP User Datagram Protocol IP Internet Protocol PPP Point to Point Protocol RFCOMM Serial Cable emulation protocol based on ETSI TS HCI Host Controller Interface LLCAP Logical Link Control and Adaptation Protocol SDP Service Discovery Protocol TCP Telephony Control Protocol LMP Link Manager Protocol Protocols

Types Of Protocols Bluetooth Core Protocols Cable Replacement Protocol Telephony Protocols Adopted Protocols

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

2)Cable Replacement Protocol RFCOMM (Redio Frequency Communications)

3)Telephony Protocols TCS-BIN Bit by Bit Transfer Protocol

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

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

Link Types & Packet Types Synchronous Connection Oriented Asynchronous Connectionless Type

Error Correction Forward Error Correction Automatic Repeat Request

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

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

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

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

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

IrDA IrDA Is a Infrared Interface Standard Problems: 1)It Is Limited To Point To Point Connections 2)Its need For Line Of Sight

IEEE Higher Transmission Capacity Bluetooth H/W considerable Smaller Bluetooth Is 10 times smaller

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

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

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

Advantages Minimal Hardware Dimensions Low Price Low Power Consumption
