Since, May 1998 the Bluetooth SIG steers the development of the technology through the development of an open industry specification, including both protocols and application scenarios, and a qualification program designed to assure end-user value for Bluetooth products. This article highlights the Bluetooth wireless technology. Keywords: Bluetooth, Hotspot, Internet, GPRS or Wi-Fi facility,UWB. Introduction Bluetooth is a networking technology aimed at low-powered, short range applications. It was initially developed by Ericsson, but is governed as an open specification by the Bluetooth Special Interest Group . Bluetooth is a recently proposed standard for short range, low power wireless communication. Initially, it is being envisioned simply as a wire replacement technology. Its most commonly described application is that of a “cordless computer “consisting of several devices including a personal computer, possibly a laptop, keyboard, mouse, joystick, printer, scanner ,etc., each equipped with a Bluetooth card. There are no cable connections between these devices, and Bluetooth is to enable seamless communication between all them, essentially replacing what is today achieved through a combination of serial and parallel cables, and infrared links. However, Bluetooth has the potential for being much more than a wire replacement technology. This is in part because its low power consumption and potential low cost make it an attractive solution for the typical mobile devices used in adhoc networks. Bluetooth is a specification for Wireless Personal Area. It is a way to connect and exchange information and data between mobile phones, laptops, digital cameras and video games. The communication is wireless and has the range of up to 10 meters. Imagine the situation. You go to your office. You connect your notebook to the LAN port. You switch it on. It goes through the entire process of booting up and then you transfer the data to your desktop computer this around process takes around 10-15 minutes, depending upon speed of your notebook. Bluetooth will also enables to transfer files, photos, and songs from the mobile to other device. The Bluetooth comes in with a wireless headsets and it comes in free with the mobile phone or computer, the wireless headset also useful for people who like to be on the go or while driving the car, as they are hands free. This paper includes some previous work done on bluetooth scatternet. Why it is called Bluetooth? The heart of the Bluetooth brand identity is the name, which refers to the Danish king Harald "Bluetooth" Blaatand who unified Denmark and Norway. In the beginning of the Bluetooth wireless technology era, Bluetooth was aimed at unifying the telecom and computing industries .Bluetooth can be used to wirelessly synchronize and transfer data among devices. Bluetooth can be thought of as a cable replacement technology. Typical uses include automatically synchronizing contact and calendar information among desktop, notebook and palmtop computers without connecting cables. Bluetooth can also be used to access a network or the Internet with a notebook computer by connecting wirelessly to a cellular phone. Working of Bluetooth (LAN) technology, also referred to as Wi-Fi, finds itself with an increasing rate in corporate and academic office spaces, buildings, and campuses. Furthermore, with slow, but steady rate, the 802.11b technology makes inroads in pub 3.3.1 Radio Layer Bluetooth works similar to other wireless technologies. It transmits data in the form of bits (ones and zeros) over a radio frequency. This function is defined by radio layer .Bluetooth transceivers use Gaussian Frequency Shift Keying (GFSK).In GFSK, the binary zero is represented by negative frequency deviation and binary one is represented by positive frequency deviation. The Bluetooth transceivers are available in three Power classes. The range is without obstacles.
