Bluetooth is a short-range wireless technology that allows devices such as phones, headphones, laptops, and printers to connect and exchange data within around 10-100 meters. It was developed in 1994 by five companies to create a standard for linking mobile devices wirelessly using the 2.4GHz radio band. Bluetooth includes a small computer chip that handles linking devices, security functions like authentication and encryption, and allows for data transfer speeds of up to 1 Mbps between paired devices.

1. WELCOME

3. 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.

4. 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.

5. 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

6. 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.

7. • Laptops
• Cellular phones
• Headsets
• Printers
• Keyboards/mic
• GPS, etc…
• Major use in consumer electronics

9. • Responsible for link set-up between devices,
including security functions :
– Authentication
– Encryption

10. • 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

11. •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
