Question

what is bluetooth technology and how does it work???

Answer 1

Bluetooth offer low bandwidth wireless connections to become so simple to use that they can easily integrate into daily life. This provides wireless connection between the Internet and other connecting devices. Bluetooth operates on global radio-frequency standards, which works at frequency 2.4 GHz ISM band and provide license-free operation in the United States and other countries. The support of Bluetooth wireless technology within the Bluetooth Special Interest Group and in the user community is provided by 9 Promoter companies: 3Com, Microsoft, Motorola, IBM, Lucent, Ericsson, Intel, Nokia, and Toshiba.



Bluetooth devices operate in a range of about 10 meters. The communication channel support data means asynchronous and voice means synchronous communications with a bandwidth of 1 Mb/sec.



At fixed intervals, the synchronous voice channels are provided using circuit switching with a slot reservation. A synchronous link is called as synchronous connection-oriented link. By using packet switching the asynchronous data channels utilizing polling access scheme. An asynchronous link is called as an asynchronous connection-less link. A packet containing data-voice synchronous combination is also defined. This provides 64 kb/sec voice and 64 kb/sec data in bi-direction.



How does it work?

Bluetooth technology works with radio signals over short distances. The BlueSpace software formulates it all very easy on a VAIO computer. Bluetooth software is specially designed for CLIÉ and Sony Ericsson mobile phones. BlueSpace is unique Sony software, which allows VAIO computer to connect to other Bluetooth devices.

With BlueSpace software following tasks can be performed:

1)It provides Connection to other Bluetooth devices.

2)It checks the status of the connections and seeing an overview of the Bluetooth services.

3)It launches certain applications automatically when connected to other Bluetooth devices.

4)It connects automatically with communication devices when Bluetooth is started.

5)BlueSpace is delivered as standard only on VAIO computers with extended Bluetooth functionality.

6)Its services include file transfer, remotely capturing pictures, image transfer and so on.



For all Sony Bluetooth enabled devices wireless connection takes place in three steps:

1.It performs a device discovery to search for other Bluetooth-enabled devices within radio range.

2.It selects device and then perform a service discovery to search for available services or applications.

3.It establishes a connection with the device by selecting the required service or application.

Answer 2

Bluetooth is a technology that allows two electronic devices to interact with eachother wirelessly in short range. There are different types of bluetooth that are referred to as "profiles". In order to interact, two devices must support the same profiles.



An example could be a cell phone that can wireless stream music to a pair of headphones. This is called advanced audio distribution profile (AD2P).



Another might be a car that can be synced with a cell phone to allow wireless calling/answering.



Finally, some phones that are equipped with a data plan can be synced through bluetooth with a computer to act as a wireless modem. This way, you can go on the internet anywhere as long as there is a connection on your cell phone.



Before buying a phone, check to see if it supports the profiles that you need. Not all bluetooth phones support the same profiles.

Answer 3

It is a wireless connection between your phone and an ear receptacle that allows you to communicate without holding your phone. There are many bluetooth's on the market right now that are reasonably priced. It is worth having for a matter of convenience and overall call quality.

Answer 4

it is the advanced form of bluetongue technology in which your tongue turns blue from eating a sow cone. Also, new products have come out which turn the users tongue into varios other colors. Developed by lowering the temperature of H2o and infusing the crystaline water with a blue dye. Some users have reported a numbness in the brain as a very harsh side-effect. Also known as brainfreeze. Use with caution.

the thg is both should have bluetooth...n da bluetooth should b on...



da speed of bluetooth depends upon da decive which is sending...usually it is...50-100kb/sec

Answer 6

blue tooth is the way of connecting two device having the blue tooth technology without wires(wireless).

u could connect one blue tooth to another by switching on bluet ooh on both devise then a search will be perform by any of the two device if the another blue tooth device is present in the range (usually 10meters) then the blue tooth device is connected to that.



simply it is an wireless connection

Answer 7

Bluetooth is a low-power-consumption and short-range wireless technology for personal area networks (PANs). It connects your personal electronic devices, such as laptops, mobile phones, digital cameras, audio equipments, and printers, without the clutter of cables. The Swedish telecom giant Ericsson originally developed Bluetooth. The name is inspired by King Harold Bluetooth, known for his unification of previously warring tribes from Denmark, Norway, and Sweden. Likewise, the Bluetooth technology was intended to unify and connect different personal electronic devices.



How to Use Bluetooth



To use Bluetooth, you have to set up the devices and authenticate them with each other. The exact instructions, obviously, are different for each device, and you have to look them up in the device's manual. However, the same general principles apply. Below is a brief overview of the process.



Devices and Drivers

By default, Bluetooth is turned off on most handheld devices in order to reduce power consumption.

For most Bluetooth-compatible handheld devices, such as smartphones or PDAs, you do not need to install additional hardware or software to enable Bluetooth. You just need to navigate to the connectivity configuration menu on the device UI, and turn on the Bluetooth radio. Once Bluetooth is on, you can typically see a Bluetooth symbol or a small black dot on the idle screen. The device also has built-in Bluetooth utility software for changing the device name, changing the discovery mode, authenticating with other devices, sending files/messages, etc.



For computers, setting up Bluetooth is a little more complex. You first need to make sure that there is Bluetooth hardware installed on the computer. If not, you can easily purchase a USB-based Bluetooth dongle and just plug it in. If you do not want the dongle to stick out of your computer or have no spare USB port, you can purchase a Bluetooth card that can be installed inside of the computer. Different operating systems provide different levels of support for Bluetooth hardware.



Mac OS X: If you use a late-model Mac computer with the Mac OS X operating system, you can simply open System Preferences and click on the Bluetooth icon to turn on Bluetooth. The Mac OS X system has built-in Bluetooth utilities to perform common network tasks (e.g., searching for nearby devices, transferring files). It is recommended that you leave the Bluetooth icon in the system menu bar so that you can easily access the Bluetooth features with one click of the mouse.



Windows before XP with SP2 (Service Pack 2): If your Windows computer has an operating system older than Windows XP with SP2, you have to install the driver software that comes with your Bluetooth dongle or card. The driver software comes with common utilities to configure the Bluetooth properties of the PC and communicate with other devices on the Bluetooth network.



Windows XP with SP2 and later: A major new feature in Windows XP SP2 is the built-in Bluetooth support. When you plug in the Bluetooth dongle, Windows prompts you to install new hardware and select the appropriate driver already bundled in the operating system. After the hardware is successfully installed, you will see a Bluetooth icon in the system icon tray. Click on that icon to access Bluetooth network utilities.



Linux: To make Bluetooth work on a Linux box, you have to make sure that you have a recent Linux kernel (2.4.22 or the 2.6 series). Then, you can install the BlueZ Bluetooth support package. However, as a command-line tool, BlueZ is not particularly user-friendly. You have to issue multiple complex commands to complete simple tasks like authenticating a peer device or transferring files. If you use the GNOME or KDE desktop systems, you can download the GNOME Bluetooth Subsystem or KDE Bluetooth Framework packages to add an easy-to-use GUI for Bluetooth network utilities.



Since the Bluetooth drivers in the operating system must support Bluetooth profiles, those drivers come with native utilities for communication tasks defined in the profiles, such as device authentication, business card/file transfer, PIM synchronization, and so on. Nokia Smartphone Hacks covers details on how to set up Bluetooth on Mac, Windows, and Linux computers to connect to a smartphone.
