ABSTRACT
Bluetooth is one of the most recent development in wireless technology. Bluetooth technology allows wireless connection between various communication devices with ease. The paper begins with a brief introduction of Bluetooth technology and the need for it. It then explains other two types of wireless communication viz. Infrared communication and Cable Synchronization and the advantages of Bluetooth over these. It also explains the techniques by which Bluetooth avoids interference from other electronic
devices. Further an example is illustrated to explain how Bluetooth technology actually works. Paper also shows some present uses of Bluetooth and the conclusion attempts to give the present and future use of Bluetooth and how this new technology can change the world of communication.

INTRODUCTION

The Bluetooth wireless technology allows users to make effortless, wireless and instant connections between various communication devices, such as mobile phones and desktop and notebook computers. Since it uses radio transmission, transfer of both voice and data is in real-time. The sophisticated mode of transmission adopted in the Bluetooth specification ensures protection from interference and security of data.
The Bluetooth radio is built into a small microchip and operates in a globally available frequency band ensuring communication compatibility worldwide. The Bluetooth specification has two power levels defined; a lower power level that covers the shorter personal area within a room, and a higher power level that can cover a medium range, such as within a home. Software controls and identity coding built into each microchip ensure that only those units preset by their owners can communicate.

BLUE TOOTH TECHNOLOGY


ABSTRACT

Bluetooth is a radio frequency specification for short range, point to point and point to multi point voice and data transfer. Bluetooth technology facilitates the replacement of cables normally used to connect one device to another by a short range radio link. With the help of blue tooth we can operate our keyboard and mouse without direct connection of CPU. Printers, fax machines, headphone, mouse, keyboard or any other digital devices can be part of Bluetooth system.

In spite of facilitating the replacement of cables, Bluetooth technology works as an universal medium to bridge the existing data networks, a peripheral interface for existing devices and provide a mechanism to form short ad hok network of connected devices away from fixed network infrastructures.

Due to their independence on short range radio link, Bluetooth devices do not require a line of site connection in order to communicate. Therefore a computer can print information on a printer if printer is in inside the room. Two blue tooth devices can talk to each other when they come within range of 10 meters to each other.

Bluetooth technology represents an opportunity for the industry to deliver wireless solutions that are ubiquitous across a broad range of devices.

ABSTRACT:
The objective of this paper is to provide an informative overview about Bluetooth technology, which has in fact already become a global de facto standard for wireless connectivity. In this report we are including the fundamentals of Bluetooth, how it evolved, the architecture, the working, and the technical specifications. Moreover, we are also penning down a few of its advantages and disadvantages from a consumer and provider point of view which further leads on to describing a few of its vast and varied applications. We conclude on the note of what Bluetooth technology presently is and what potential it has in our world and life.
Bluetooth is a global standard for wireless connectivity. Bluetooth technology facilitates the replacement of the cables used to connect one device to another, with one universal short-range radio page link operating in the unlicensed 2.45 GHz ISM band. Bluetooth can imitate a universal bridge to attach the
existing data networks, and also as a mechanism for forming ad-hoc networks. Designed to operate in noisy frequency environments, the Bluetooth radio uses a fast acknowledgement and frequency hopping scheme to make the page link robust. The main objectives of Bluetooth technology are:
 Cable replacement
 Small size
 Low cost
 Low power
INTRODUCTION:
During the past two decades, the advancement in microelectronics and VLSI technology dipped down the cost of many consumer electronic products to a level, which was affordable for the common man. The sale of cellular phones is predicted to reach 1 billion in 2005. With increase in the number of electronic devices, comes in the need of connecting them together for maximum interoperability and utilization. Bluetooth is a technology devised to replace the cables.
Bluetooth can imitate a universal bridge to attach the existing data networks, and also as a mechanism for forming ad-hoc networks. Designed to operate in noisy frequency environments, the Bluetooth radio uses a fast acknowledgement and frequency hopping scheme to make the page link robust.At the nominal operating range of 10 meters, Bluetooth creates a 10-meter radius bubble around the mobile phone that instantly connects the Bluetooth Personal Area Network (PAN) to an existing Wide Area Network (WAN) such as TDMA, CDMA, GPRS or GSM. Within the PAN sphere, Bluetooth provides a common wireless transport method for all communication traffic data or voice.A wireless headset handles incoming and outgoing voice calls while a PDA,digital camera, MP3 player and a mobile computer exchange emails, pictures, or music over the web. Bluetooth turns the mobile phone into a communication gateway where information flows freely without boundaries. Outside of the PAN, Bluetooth can be utilized as an Instant Access Point facilitating the means for electronic commerce, personal finance, or data collection.
HISTORY:
In 1994, Ericsson in Sweden launched an initiative to study a low-power, low-cost radio interface between mobile phones and their accessories. After three years. In 1997, Ericsson approached various manufacturers of mobile electronic devices to discuss the development and promotion of this short range wireless radio link, as alone this phenomenon could not be implemented.

ABSTRACT
Blue tooth is a standard developed by a groupof electronics manufacturers that allows anysort of electronic equipment – fromcomputers to cell phones and keyboards toheadphones – to make its own connectionswithout wires, cables or any direct actionfrom the user. The technology encompasses asimple low-cost, low-power, global radiosystem for integration into mobile devices.Such devices can form a quick ad-hoc secure“Piconet” and communicate among theconnected devices. This technology createsmany useful mobile usage models becausethe connections can occur while mobiledevices are being carried in packets andbriefcases (therefore, there are no line-ofsightrestrictions). This paper provides a briefintroduction of Bluetooth technology and itsworking. It also gives some of applications,features and benefits. Finally, theimplementation issues of Bluetoothtechnology are observed.Bluetooth has to receive an overwhelmingsupport of all the digital and computerizedmanufacturers to become a basic unit in aproduction process. Acceptance by thosecompanies outside the SIG will hold back theimplementation of Bluetooth in all devices inthe future.Bluetooth is a radio system designed forconnecting a variety of mobile devices in asecure ad-hoc fashion. The Bluetoothspecification is definitely real and is beingwidely adopted by industry leaders. Thepossibilities for new applications are veryexciting with this versatile technology.
INTRODUCTION
Today wireless communication is one of thefastest growing technologies. One of thepromising technologies for WLAN’s(Wireless Local Area Network) is BLUETOOTH. LAN (Local Area Network)is a computer network designed forconnecting devices in a limited geographicarea such as a building or a campus where asWLAN is a LAN, which uses unguidedmedia (Without using cables or anyconnections). It is used for connectingroaming devices & provides a high-speedbackbone network to enable security.Bluetooth technology was born in 1994.Firstversion was released in July 1999.
WHAT IS BLUETOOTH?
Bluetooth is a name given to the noveltechnology that uses short range, radio link,intended to replace the cables connectingportable and/or fixed communicating devices.Such as mobile phones, desktops, notebookcomputers, cameras, printers, coffee makers,telephones etc.ORBluetooth wireless technology is an openspecification for a low cost, low power, shortrange, radio technologies for ad-hoc wirelesscommunication of voice and data any wherein the world.
THE NAME BLUETOOTH COMESFROM…
Bluetooth is named for Harald Blatand, theking of Denmark who united Denmark andNorway. Blatand translates into Bluetooth inEnglish. The Ericsson Company originallystarted Bluetooth as a project.Similarly, in the beginning of the Bluetoothtechnology era, Bluetooth was aimed atunifying the telecom and computingindustries.
THE REASON WE CAME TOBLUETOOTH…
Let us take an example of telephones forcables where as mobiles are wireless.Because of the problem of interference overcabling we came to Bluetooth technology.This Bluetooth is also a cable replacementtechnology i.e. wireless.
BLUETOOTH IS WIRELESS…
Blue tooth uses Omni-directional radio waveswhich even operate in the unlicensed ISMband at 2.4GHZ that can be transmittedthrough walls and non-metal barriers.Bluetooth uses 1600 times/sec frequencyhopping to avoid interference.
BLUETOOTH CONTROLLER…
The Bluetooth Special Interest Group (SIG)This group worked together to define andpromote an open, royalty-free specification.This group also defines a certificationprogram for Bluetooth products to ensureproduct compatibility across manufacturers.The Bluetooth SIG includes promotercompanies 3Com, Ericsson, IBM, Intel,Lucent, Microsoft, Motorola, Nokia andToshiba, and more than 2000Adopter/Associate member companies.
FEATURES
Universal short-range (up to 100 mts) radiocommunication standard.Runs at 2.4GHz band, which is nearmicrowave frequency.Performs fast frequency hopping between 79points to avoid interference i.e., 1600times/sec.It is full-duplex.Low power, 32-100mA during sustained datatransmissions between devices. Devicesautomatically switch to power saving mode.Transfers data at 721 Kbps (Kilo Bits PerSecond), which is 3 – 8 times the averagespeed of parallel and serial ports respectively.Bandwidth is wide enough to carry voice anddata signals.300 – 400 Kbps real data rate.
NETWORKS
Bluetooth defines two types of networks.
♦ Pico net
♦ Scatter net
PICONET
It is a small subset of Bluetooth devices thatshare the same physical channel in an ad-hocfashion.Pico net comprises of eight stations in whichonly one serves as master & the rest asslaves.All the slave stations synchronize their clocks& hopping sequence with the master. Anindefinite number of parked devices remainssynchronized with the Pico net but is notactive. A slave in the parked state issynchronized with the master but cannot takeplace in communication until it moves fromparked state to active state.
