CHAPTER ONE
1.0 INTRODUCTION
Bluetooth is a wireless technology standard for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands, from 2.400 to 2.485 GHz, and building personal area networks (PANs). It was originally conceived as a wireless alternative to RS-232 data cables. Wireless signals transmitted with Bluetooth cover short distances, typically up to 30 feet (10 meters).
It is achieved by embedded low cost transceivers into the devices. It supports on the frequency band of 2.45GHz and can support upto 721KBps along with three voice channels. This frequency band has been set aside by international agreement for the use of industrial, scientific and medical devices (ISM).rd-compatible with 1.0 devices.
Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 30,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard [3, 4, 5].
1.1 BACKGROUND OF THE STUDY
We all have experienced the inconvenience that arises when we start connecting peripherals to a computer, or when we connect other electronic devices, with a lot of cables that becomes difficult to control. Then we start to think how easy it would be if all these connections were done using a different way from the physical cables, like infrareds, radio or microwaves. The companies of computer science and telecommunications needed to develop an opened, low cost interface to make easier the communication between devices without using cables. This is the origin of the technology which key name is "Bluetooth". This is a fact nowadays, but now another problem arises and is that there are a lot of standards and technologies, incompatible between them. What we need now is a universal, valid device for the connection of all kinds of peripheral, and that works in a transparent way for the user. This is Bluetooth. Opposite to other current technologies, like infrared promoted by the IrDA (Infrared Data Association) or DECT, Bluetooth has the support of the industry of computer science and telecommunications, which in some way guarantees the success. Although there is a high number of manufacturers who incorporate the interface IrDA in their telephones, included Ericsson, Motorola and Nokia, the use turns out to be frustrating for many users who treat without success to download information from their PC or PDAs to their mobile telephones, or vice versa. The devices that Bluetooth incorporates are recognized and speak each other in the same way as a computer does it with the printer. The low price of these products means that the incorporation in any device supposes a low cost for the manufacturer and the user.
1.2 AIM AND OBJECTIVE OF THE STUDY
The main of this work is to study a network that aimed to ease communication between mobile devices by providing a cable replacement.
1.4 PURPOSE OF THE STUDY
The purpose of this work is to enabled consumer electronics such as phones, cameras, televisions, speakers and headphones simplify data sharing between devices. A Bluetooth mobile phone, for example, can wirelessly connect to a headset to make hands-free calling easier or can send pictures to another phone or computer.
- It removes the problem of radio interference by using a technique called Speed Frequency Hopping. This technique utilizes 79 channels of particular frequency band, with each device accessing the channel for only 625 microseconds, i.e. the device must toggle between transmitting and receiving data from one time slot to another. This implies the transmitters change frequencies 1,600 times every second, meaning that more devices can make full use of a limited slice of the radio spectrum. This ensures that the interference won’t take place as each transmitter will be on different frequencies.
- The power consumption of the chip (consisting of transceiver) is low, at about 0.3mW, which makes it possible for least utilization of battery life.
- It guarantees security at bit level. The authentication is controlled using a 128bit key.
- It is possible to use Bluetooth for both transferring of data and verbal communication as Bluetooth can support data channels of up to 3 similar voice channels.
- It overcomes the constraints of line of sight and one to one communication as in other mode of wireless communications like infrared
1.6 AREA OF APPLICATIONS
Cordless Desktop: All (or most) of the peripheral devices (e.g., mouse, keyboard, printer, speakers, etc.) are connected to the PC cordlessly.
Ultimate headset: It can be used to allow one headset to be used with myriad devices, including telephones, portable computers, stereos, etc.
Automatic synchronization: This usage model makes use of the hidden computing paradigm, which focuses on applications in which devices automatically carry out certain tasks on behalf of the user without user intervention or awareness.
Multimedia Transfer:- Exchanging of multimedia data like songs, videos, pictures can be transferred among devices using Bluetooth.
1.7 SCOPE OF BLUETOOTH
The connections have a maximum range of 10 meters, though using amplifiers it is possible to come up to 100 meters, but creating some distortion interferes. Maybe it doesn’t look too much, but it is necessary to remember that these devices were created by the intention of using them in closed environments and little distances.
1.8 BLUETOOTH LIMITATIONS
There are some downsides to Bluetooth. The first is that it can be a drain on battery power for mobile wireless devices like smartphones, though as the technology (and battery technology) has improved, this problem is less significant than it used to be.
Also, the range is fairly limited, usually extending only about 30 feet, and as with all wireless technologies, obstacles such as walls, floors, or ceilings can reduce this range further.
The pairing process may also be difficult, often depending on the devices involved, the manufacturers, and other factors that all can result in frustration when attempting to connect.
