A wireless personal area network (WPAN) technology from the Bluetooth Special Interest Group (www.bluetooth.com) founded in 1998 by Ericsson, IBM, Intel, Nokia and Toshiba. Bluetooth is an open standard for short-range transmission of digital voice and data that supports point-to-point and multipoint applications. Some of the first Bluetooth applications have been for cellphones, providing a wireless connection to a headset and to an automobile's audio system for hands-free operation.
Specifications-
Bluetooth provides up to 720 Kbps data transfer within a range of 10 meters and up to 100 meters with a power boost. Unlike IrDA, which requires that devices be aimed at each other (line of sight), Bluetooth uses omnidirectional radio waves that can transmit through walls and other non-metal barriers. Bluetooth transmits in the unlicensed 2.4GHz band and uses a frequency hopping spread spectrum technique that changes its signal 1600 times per second. If there is interference from other devices, the transmission does not stop, but its speed is downgraded.
King Blatan of Denmark-
The name Bluetooth comes from King Harald Blatan (Bluetooth) of Denmark, who in the 10th century, began to Christianize the country. Ericsson, a Scandinavian company, was the first to develop this specification.
The first major Bluetooth application was for cellphone headsets such as this Cardo Systems unit (www.cardowireless.com). This means using two wireless systems: Bluetooth from ear to cellphone and the carrier's air interface from cellphone to tower, which would typically be CDMA or TDMA..
