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
