Definition of Bluetooth Bluetooth is a short range (10-100 m) and low-cost wireless network system to replace cables and give RF connection between consumer devices.

What is Bluetooth? Why this name? When does it appear? Bluetooth is a short-range wireless communications technology. Why this name? It was taken from the 10th century Danish King Harald Blatand who unified Denmark and Norway. When does it appear? 1994 – Ericsson study on a wireless technology to link mobile phones & accessories. 5 companies (Ericssn,Nokia,IBM,Toshiba & Intel)joined to form the Bluetooth Special Interest Group (SIG) in 1998. First specification released in July 1999.

Uses the radio range of 2.45 GHz Theoretical maximum bandwidth is 1 Mb/s Several Bluetooth devices can form an ad hoc network called a “piconet” – In a piconet one device acts as a master (sets frequency hopping behavior) and the others as slaves – Example: A conference room with many laptops wishing to communicate with each Other

Allows up to 8 devices to communicate in a local network called a Piconet, also known as a Personal Area Network or PAN Because of its low power consumption, its range is limited to 10 m. However, range can be increased to 100 m by employing a scatternet topology or a higher powered antenna Three classes of Bluetooth devices -Class 3 radios – have a range of up to 1 meter or 3 Feet. -Class 2 radios – most commonly found in mobile devices – have a range of 10 meters or 30 feet -Class 1 radios – used primarily in industrial use cases – have a range of 100 meters or 300 feet

The Bluetooth standard is maintained and published by the Bluetooth Special Interest Group (SIG) Includes thousands of member companies Covers topics such as interoperability, testing and qualification of bluetooth devices Most important, outlines the specifications for: - Bluetooth Radio - Baseband - LMP – Link Manager Protocol

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

Infrared IrDA (WPAN) : synchronization, link between a phone and a laptop… – Less flexible than Bluetooth, need of a line of site – Comparable data rate Wi-Fi (WLAN) : Wireless LAN access – Far higher bandwidth and data rate than Bluetooth – Higher power consumption than Bluetooth – Requires infrastructure investment

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 -Must not destroy current product benefits Key Success Factors -Interoperability -Mass Production at Low Cost -Ease of Use -End User Experience
