What IS Bluetooth ?

• Bluetooth Is A Wireless Technology Standard For Exchanging Data Over Short Distances

• Bluetooth Is Send Multiple Data Or Some Data To Short Distance Without Using Wires

• In 1994, Ericsson Mobile Communication Ltd. Started project named “Bluetooth”.

• In 1998, Bluetooth SIG was formed and it officially adopts the project name “Bluetooth” as the name of technology.

Frequency Hopping Spread Spectrum Technology was used for data transformation

HISTORY

NEED FOR BLUETOOTH

A Cable Replacement Technology

It’s wireless.

It’s inexpensive.

You don’t have to think about it.

Personal Ad Hoc Networks

Cable Replacement

Landline

Data/Voice Access Points

What Can Bluetooth Do For You?

Connection via Bluetooth

APPLICATION EXAMPLES:

• A Bluetooth–mouse• A Bluetooth-keyboard • Cable-less connection to printers• Use e-mail while your portable PC is

still in the briefcase!

BLUETOOTH–MOUSE

And much more ……….

PICONETS• A Set Of BLUETOOTH Devices Sharing A Common Channel Is Called A PICONET

SCATTERNETS

• Scatter nets are two or more independent and non-synchronized piconets that communicate with each other by making bridge nodes.

ARCHITECTURE STRUCTURE

COMPONENTS OF ARCHITECTURE

• Radio Front End (RF)• Defines characteristics of RF, frequency bands,

channel arrangements & receiver sensitivity level.

• Logical Link Control & Adaptation Protocol (L2CAP)• For transporting bigger data products to higher layer.

• Service Discovery Protocol (SDP)• To query and discover services supported by peer

Bluetooth devices.

• Link Manager Protocol (LMP)• PICONET, master slave role assignments and link

configuration.• Security configuration by device authentication using

secret key.• RFCOMM

• Provides transport capabilities for high level services.

CREATION OF A SCATTERNET

• A Master orSlave can becomeSlave in anotherpiconet by beingpaged by theMaster in thisother piconet.

NETWORK FORMATION AND CONTROL

: Future of Bluetooth :• Success of Bluetooth depends on how well it is integrated into

consumer products

• Consumers are more interested in applications than the technology

• Bluetooth must be successfully integrated into consumer products

• Must provide benefits for consumer

Key Success Factors :• Interoperability• Mass Production at Low Cost• Ease of Use• End User Experience

ADVANTAGES OF BLUETOOTH

• Bluetooth is used widely across countries and almost by everyone.

• It has simple features.

• It is free of charge and not added to our budget.

• It has the ability to keep our information private.

• It provides ranges of up to 100 meters.

DISADVANTAGES OF BLUETOOTH

•More battery power when Bluetooth is enable on the phone all

day.

•Throughout all device, when using Bluetooth internet, the

connection sometimes may run very slow so Bluetooth internet is

not highly suggested for all cases.

• Infrared can have data rates of up to 4 M Bps, which provides

very fast rates for data transfer, while Bluetooth only offers 1

MBps

CONCLUSION

•Bluetooth is a short range radio link wireless technology

used to connect various device by a invisible link getting

rid of wires.

•Last but not the least, WHENEVER THINK OF

WIRELESS,”THINK BLUETOOTH”, this is the best way of

communication.
