Transcript of Bluetooth ppt by Ajay
WELCOME
INTRODUCTION TO
BLUETOOTH
Bluetooth is a short-range wireless
communication technology.Bluetooth technology
allows you to share voice, data, music, photos,
videos and other information wirelessly between
paired devices.
Definition of Bluetooth
o 1994 – Ericsson study on a wireless technology to
link mobile phones & accessories.
o 5 companies (Ericsson,Nokia,IBM,Toshiba &
Intel)joined to form the Bluetooth Special Interest
Group (SIG) in 1998.
o First specification released in July 1999.
BLUETOOTH HISTORY
FEATURES• Uses the radio range of 2.45 GHz
• Range is 10 m -100 m
• Full-duplex signal
Theoretical maximum bandwidth is 1 Mb/s
• Bluetoot includes a small computer chip
containing the Bluetooth radio
Range may vary depending on class of radio used
Class 1 radios – Used primarily in industrial use cases. have a range of 100 meters or 300 feet
Class 2 radios – Most commonly found in mobile devices. have a range of 10 meters or 30 feet
Class 3 radios – Have a range of up to 1 meter or 3Feet.
• Laptops
• Cellular phones
• Headsets
• Printers
• Keyboards/mic
• GPS, etc…
• Major use in consumer electronics
BLUETOOTH DEVICES
USES OF BLUETOOTH
•Responsible for link set-up between devices,
including security functions :
– Authentication
– Encryption
LINK MANAGER PROTOCOL(LMP)
•Infrared IrDA (WPAN)
Less flexible than Bluetooth,
need of a line of site
Low data rate
•Wi-Fi (WLAN) : Wireless LAN access
Far higher bandwidth and data rate than
Bluetooth
Higher power consumption than Bluetooth
Requires infrastructure investment
COMPETING TECHNOLOGIES
•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
FUTURE OF BLUETOOTH
