DEFINITION- Bluetooth® is a industry standard that describes how mobile phones can be easily connected to other devices using a short-range wireless connection. Using this technology, users of cellular phones, get quickly connected to their car wirelessly. Once a simple one-time pairing proceedure is followed, each time the phone comes within proximity of a running car, the phone will connect automatically to the car, and the sound will then come from the car's speakers.
The technology got its unusual name in honor of Harald Bluetooth, king of Denmark in the mid-tenth century.
