What is Bluetooth?

Bluetooth is a standard for short range, low power, and low cost wireless communication that uses radio technology. Over 2100 companies around the world already support Bluetooth technology. The wireless personal area network (WPAN) technology, based on the Bluetooth specification, is now an IEEE standard under the denomination of 802.15 WPANs. This work presents an overview about the Bluetooth communication . Bluetooth wireless technology encompasses several key points that facilitate its widespread adoption: 1) it is an open specification that is publicly available and royalty free; 2) its short-range wireless capability allows peripheral devices to communicate over a single air-interface, replacing the cables that use connectors with a multitude of shapes, sizes and numbers of pins; 3) Bluetooth supports both voice and data, making it an ideal technology to enable many types of devices to communicate; and 4) Bluetooth uses an unregulated frequency band available anywhere in the world.. To fully realize the Bluetooth vision, full networking of multiple Bluetooth devices is required. This leads to the investigation of Bluetooth scatternets, which must address scatternet formation and reconfiguration, scheduling, and routing issues.
