Your Questions About Bluetooth Technology

Robert asks…

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

dknol answers:

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.

Maria asks…

What is better technology with more future bluetooth or wifi?

dknol answers:

They are two entirely different technologies. Yes, they are both wireless, but that is where the simularities end.

Bluetooth is a short range wireless standard, used to connect devices together that you used to use wires or cables for. For instance, the most common use for Bluetooth is to connect wireless headsets to cell phones.

WiFi is used to connect computers to the Internet. If you have a laptop with a WiFi card, you can connect to the internet anywhere in your house, if you have a WiFi hub. And now that entire cities like San Francisco, are offering free WiFi, you'll be able use your laptop to get onto the Internet from anywhere in the city.

Charles asks…

Is the Motrola v190 compatible with Bluetooth technology?

dknol answers:

This device supports Bluetooth profiles. In order for Bluetooth devices to communicate with one another, they must utilize the same Bluetooth profile. To determine the profiles supported by other Motorola devices, visit For other devices, contact their respective manufacturer

Mandy asks…

how do you connect your cell phone to your computer with bluetooth technology?

dknol answers:

With a blue tooth dongle. Which plugs into your usb port. You can pick them up quite cheap on eBay.
