Bluetooth was developed in 1994 as a wireless alternative to cables that connect devices like mobile phones and accessories. A group of companies formed the Bluetooth Special Interest Group to develop the Bluetooth specifications. Bluetooth allows short-range wireless connectivity between devices, replacing cables and providing mobility and reliability without cables that can break or be lost. It works by designating one device as the master that can connect with multiple slave devices at transfer rates up to 1Mbps within a self-organizing network formed whenever devices are in close proximity.

1. BLUETOOTH BASICS

2. Introduction The much hyped Bluetooth wireless technology has progressed at a snail’s pace. However it is gaining fresh momentum with a number of companies releasing Bluetooth-enabled consumer products. Let’s check out how Bluetooth drives these devices wireless.

3. BLUETOOTH HISTORY In 1994, Ericsson mobile communication began to examine alternatives to cables linking accessories with their mobile phones. This study produced the initial specification for wireless technology, with the Bluetooth Special Interest Group(SIG) founded in february 1998 by the core promoters , viz, Ericsson mobile, Intel, IBM, Toshiba and Nokia mobile . Later the core promoter group was enlarged with the inclusion of Microsoft, Agere, 3Com and Motorola.

7. How does Bluetooth actually works ? When two Bluetooth devices communicate, one device is designated the master & the other device is designated the slave. Data transfer rate between master & slave is approx. 1Mbps. The Bluetooth network is completely self-organising and can be established whenever two or more Bluetooth devices are close enough to establish radio contact. The devices automatically search for other Bluetooth enabled device in their vicinity. Upon establishing a contact, information is exchanged, which determines whether the connection should be completed or not. Bluetooth devices connect via a process of authorisation & authentication .
