Bluetooth wireless technologies essay

The Bluetooth specification limits the radio output power exactly to that actually required. The main principle of its work shows that physically, a typical Bluetooth device is a radio receiver and radio transmitter, operating on the frequency of Observing the topic of the Bluetooth technology appearance and development with many details, we can mention that the use of Bluetooth is not limited to miniature computers and a variety of fashionable technological devices.

Bluetooth radio modules operate in the unlicensed ISM band at 2. Invented by telecom vendor Ericsson in This band provides license-free operation in the United States, Europe, Japan, and most industrialized nations worldwide.

The main purpose of Bluetooth — is support of cost-effective in terms of current consumption and low-cost radio communication between the various types of electronic devices, with considerable importance giving to the compactness of electronic components, which make possible to use Bluetooth devices in a compact size of a wrist watch.

Nowadays Bluetooth opens up tremendous opportunities for inventors.

Frequencies that are used in the technology determine the possibilities of Bluetooth data transmission. The Bluetooth chip, being a transceiver, operating on the frequency of 2.

The chips can also be used in consumer electronics, which means that now a user with a Pocket PC or mobile phone can give any command to a Bluetooth wireless technologies essay oven or TV set. Thus, low-power transmitter consumes only 0. Bluetooth Since the dawn of time, man has used tools to automate fundamental tasks.

The implication is that Bluetooth does the same with communications protocols, uniting them into one universal standard. Bluetooth wireless technologies essay merely took this to the next level of automation, making the line move on its own.

Therefore, Bluetooth devices designed specifically for France, Spain or Japan will not work with devices designed for the rest of the world.

This capability can be used to create assembly-line production, to store calibration data available only after final testing, or it can be used to improve programs on finished products. If no data is transmitted, then people can transmit up to three audio channels via a Bluetooth connection.

Association for Supervision and Curriculum Development, At the time of this proposal he was reading Frans G. Power transmitted by the Bluetooth: Spectrum spreading is accomplished by frequency hopping up to hops per second on 79 channels between 2.

A Time Division Duplex scheme is used for full-duplex transmission. The user does not have a headache about cables, drivers, or anything else; everything that is required of the user is to make sure that Bluetooth devices would be located close enough to each other; while everything else Bluetooth devices and software should take care of themselves.

It also would provide a basis to small portable devices to be connected to each other in a special way ad hocgiven for a particular purpose. Those early steam vehicles eventually lead to breakthroughs in Great Britain where steam-driven motor cars became more and more complex with innovations to make them more automated to include hand brakes, multi-speed transmissions, and more controlled steering being added.

The Elvis Speed 20 and 25 models of the s were the first cars to have synchromesh in the gearbox, making shifting into what we equate it with today: The emphasis is on instant connectivity between devices that manage personal data or which facilitate data sharing between small groups of individuals Wireless communication adds value for these types of usage models by reducing complexity i.

Dwelling on perspectives of the Bluetooth technology development, it is worth mentioning that the Bluetooth standard was developed with the expectation of low power, so its impact on the human body is minimized.

Master defines a template on which operate all slave-devices of its piconet, and synchronizes its operation.

At the beginning, giving general information about the Bluetooth technology it is important to state that Bluetooth is a firm and well-established communication standard for wireless communications over short distances.

EEPROM memory makes it easier to apply microcontrollers to devices where permanent storage of various parameters is needed codes for transmitters, motor speed, receiver frequencies, etc.

In this part of the paper we can mention that it is very easy to use the Bluetooth technology, but speaking of wireless connection, the issue of security of such a connection is also necessary to discuss. In other words, the purpose of the founders was to create the technology which would be consistent with such specifications that optimize the use of all mobile, computing and communication devices, and also provide: It replaces a bunch of separate cables joining one device to another via one universal radio link with a small radius of action.

The main feature of Bluetooth is that the various Bluetooth devices are connected to each other automatically, once they come within reach. This policy has enabled many companies to actively engage in the development of devices with Bluetooth, which have been demonstrated at different shows in large numbers.

Bluetooth technology has no lineof sight requirements making it a potential replacement for infrared ports. In addition, a standard Bluetooth transceiver, besides the focus from frequency patterns and the need for synchronization, provides data encryption key to the effective length of 8 to bits, and a choice of unilateral or mutual authentication of course, users can do it without any authenticationwhich allows to provide the stability of the resulting encryption under the laws of each country some countries prohibit the use of a strong cryptography Richards, Each piconet supports up to 3 simultaneous full duplex voice devices CVSD.

The width of the channel for Bluetooth devices is Thus, the use of Bluetooth is not more dangerous than the Internet connection, in which all hubs are also connected electrically, but it does not mean getting unconditional access to any resource. Speed and code compression are the superiority of this RISC microcontroller compared to other 8-bit microcontroller.

New Perspectives on Computer Concepts Toshiba Corporation, Tokyo, has set Bluetooth and voice recognition technologies together in a wireless headset to enable users to control consumer electronics, appliances, and personal computers by means of spoken commands while listening to music or the audio from TV.

This free Information Technology essay on Essay: Bluetooth is perfect for Information Technology students to use as an example. Thus Bluetooth is a wireless LAN technology designed to connect devices of different functions such as telephones, computers, printers, cameras, etc. A Bluetooth LAN is an Ad hoc network.

Since, from the above example, you can modify your device to get connected to the internet via the Bluetooth technology purchasing a device that has a Bluetooth technology is a better choice as you can get two technologies in one ; internet connectivity (the function of Wi-Fi is achieved) and Bluetooth technology.

Nowadays a short word Bluetooth became very popular all over the globe. All people have heard that this technology is wireless. However, similar technologies existed much earlier, but none of them did not have in the past, and does not have in our times such a powerful and comprehensive support.

No Need for Cables with Bluetooth Essay - Introduction Bluetooth is a wireless LAN technology designed to connect devices of different function such as telephone, notebooks, computers (desktop and laptop), cameras, printers and coffe makers.
