Definition of Bluetooth

 Bluetooth is a short-range wireless communications technology.  It was taken from the 10th century Danish King Herald Blatand  Erikson, Nokia, IBM, Toshiba & Intel joined to form the Bluetooth Special Interest Group (SIG)  First specification released in July 1999.

 Uses the radio range of 2.45 GHz  The maximum bandwidth is 1 Mb/s  Several Bluetooth devices can network called a “Piconet” Example: A conference room with many laptops wishing to communicate with each Other.

Laptops Cellular phones Personal Digital Assistants Headsets Printers Keyboards/mice GPS Major use in consumer electronics

Allows 8 devices to communicate in a local network known as Personal Area Network or PAN. Its low power consumption, its range is limited to 10 m. range can be increased to 100 m by higher Powered antenna. Three classes of Bluetooth devices  Class 3 radios – range of 1 meter or 3 Feet.  Class 2 radios – range of 10 meters or 30 feet  Class 1 radios –range of 100 meters or 300 feet

The Bluetooth standard is maintained by Bluetooth Special Interest Group Covers topics such as inter operability, testing and qualification of Bluetooth devices Most important, outlines the specifications for:  Bluetooth Radio  Baseband  LMP – Link Manager Protocol

Success of Bluetooth depends on how well it is integrated into consumer products  Consumers are 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

R EQUIREMENTS  Low cost as cables – chip $5  Secure as cables – must support authentication and encryption  Must support both data and voice.  Must connect to a variety of devices.  Must be able to function in a noisy environment.  Must be low power, compact and global.
