Bluetooth is an alliance between mobile communications and mobile computing companies to develop a short-range communications standard allowing wireless data communications at ranges of about 10 or 25 or 100 meters.

                                                            The Bluetooth specification was outlined in early 1999, with Bluetooth-enabled mobile terminals such as laptops, smart phones, handheld computers and so on likely to be first available during the year 2001.

Communication Speed

Bluetooth will encompass both a standard communications interface and a low-cost computer chip. It is a cross between the DECT (Digital European Cordless Telephone) and iRDA (infra Red Data Association) technologies. Bluetooth was conceived by Ericsson, but founded by Nokia, Ericsson, IBM, Intel and Toshiba. The Bluetooth Interest Group has since been joined by hundreds of companies including Motorola, Qualcomm, Compaq, Dell, 3Com, Psion Dacom and Lucent. Bluetooth does NOT involve mobile network transactions- its spectrum is freely available to use in the unlicensed spectrum area (at 2.45 gigahertz). Data transmission speeds using Bluetooth are expected to be between 720 kbps and one megabit per second (Mbps).

This kind of synchronization and exchange of data are Bluetooth’s major applications, as are electronic commerce applications such as electronically paying for parking meters, bus tickets, shopping, movies and so on. Smart offices are envisaged in which an employee with a Bluetooth device is automatically checked in when entering the building and this triggers a series of actions such as lights and PCs being switched on. The Bluetooth partners see one of its main advantages as being that it does not need to be set up- Bluetooth runs in the background and line of sight is not even needed for the machines to automatically initiate and trigger processes. Such proactive intelligence could turn out to be a nuisance rather than a convenience for Bluetooth users unless it is under the control of the device owner(s). Indeed, the Bluetooth standard does incorporate these kinds of control mechanisms, since each device is assigned a unique 12 byte address and to connect to that device, its address must be known. There will also be an enquiry feature so to search for other Bluetooth-enabled devices within range.

Local Area Networks

Bluetooth will facilitate wireless Local Area Networks in which networks of different handheld computing terminals and mobile terminals can communicate and exchange data, even on the move and when there is no line-of-sight between those terminals. Bluetooth will mean that if users have several (Bluetooth-enabled) portable terminals, they can nonetheless use them with all the advantages of an integrated smart phone, without having to re-enter data or find the most recent versions on different terminals
