About Bluetooth!!!

1. Bluetooth
Please Turn Off your Bluetooth …

2. 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

3. HISTORY
• 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

4. NEED FOR BLUETOOTH

10. And much more ……….

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

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

13. ARCHITECTURE STRUCTURE

14. 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.

15. • 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.

16. CREATION OF A SCATTERNET
•
A Master or
Slave can become
Slave in another
piconet by being
paged by the
Master in this
other piconet.

17. NETWORK FORMATION
AND CONTROL

18. : 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

19. 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.

20. DISADVANTAGES OF BLUETOOTH
battery
• More all day.
phone
power when Bluetooth is enable on the
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
data rates of up to M Bps, which
• provides very haverates for data transfer,4while Bluetooth
fast
only offers 1 MBps

21. CONCLUSION
a short range radio link wireless
• Bluetooth isused to connect various device by
technology
a invisible link getting rid of wires.
THINK OF
• Last but not the least, WHENEVERthis is the
WIRELESS,”THINK BLUETOOTH”,
best way of communication.
