INTRODUCTION  Bluetooth is an inexpensive, short- range, low-power wireless networking technology developed to replace cables and wires.  Key features of Bluetooth wireless technology include robustness, low power, and low cost.  This technology can work anywhere and everywhere. Bluetooth enabled device, almost everywhere in the world, can connect to other Bluetooth enabled devices in proximity.

HISTORY  The word "Bluetooth" is taken from the 10th century Danish King Harald Bluetooth  Bluetooth technology was first developed by Ericsson and then formalized by a group of electronics manufacturers known as the Bluetooth Special Interest Group (SIG)  When Bluetooth was officially introduced in 1998, it’s intended basic purpose was to be a wire replacement technology in order to rapidly transfer voice and data.  A lot has changed since the first Bluetooth Core Specification Version was introduced in Recently in 2003, the Bluetooth SIG announced version 2.1 of Bluetooth.

BLUETOOTH COMMUNICATION

OPERATION Bluetooth networking transmits data via low-power radio waves. It communicates on a frequency of 2.45GHz. This frequency band has been set aside by international agreement for the use of industrial, scientific and medical devices (ISM). Bluetooth networking transmits data via low-power radio waves. It communicates on a frequency of 2.45GHz. This frequency band has been set aside by international agreement for the use of industrial, scientific and medical devices (ISM). Bluetooth uses a technique called spread-spectrum frequency hopping that makes it rare for more than one device to be transmitting on the same frequency at the same time. Bluetooth uses a technique called spread-spectrum frequency hopping that makes it rare for more than one device to be transmitting on the same frequency at the same time.

 Bluetooth devices avoid interfering with other systems is by sending out very weak signals of about 1 milliwatt  Even with the low power, Bluetooth doesn't require line of sight between communicating devices  The user doesn't have to press a button or give a command -- the electronic conversation happens automatically

SPECIFICATION  Bluetooth 1.0 and 1.0B  Bluetooth 1.1  Bluetooth 1.2  Bluetooth 2.0
