In this article I will talk about Bluetooth. You must be thinking what is this Bluetooth? Is it something related to cosmetics or something related to teeth or may be something…
Well to begin with, Bluetooth is a new technology named after the 10th century Danish king Harald Bluetooth Blatand who ruled part of Scandinavia in 960 AD .He helped unite his part of the world. As the name implies that Bluetooth would be the technology to unite the mobile world.
Bluetooth device is the revolutionary device launched by L.M Ericsson, to integrate its phone with all Internet enabled devices. Two L.M Ericsson telephone employees, the Swedish born Sve Mattison and his Dutch colleague, Jaap Haartsen, originally designed Bluetooth technology in 1994.
Nowadays, you have to either manually enter the names and phone numbers of all your contacts or in other advance way you can use a cable to connect your phone and PC and can run some application to synchronize the contact information.
With Bluetooth there are so many exciting applications like, nowadays whenever you come to office, you have to do so many setup to get to start to work, like you have to connect your notebook to USB port, you switch it on, then your notebook gets boot up and after that only you are able to log in. All this process takes some of your time. Now think about the situation where you walk into the office switch on the notebook and get ready to do work. This is possible with Bluetooth, it makes your notebook to start communicating with your server via radio signals, not require you to connect it to the USB port.
Even car manufacturers are not left behind; car manufacturers such as BMW, Lexus and Toyota have equipped some of their models with Bluetooth car kits. This allows you to use the features of your cell phone through the car’s audio system while the phone itself stored in the trunk for instance.
Now the question arises, how the Bluetooth technology works?
Bluetooth operates in globally available low radio frequency at 2.4 GHz and supports data speed of up to 721 Kbps, as well as three voice channels.
To make use of Bluetooth technology you have to make sure the new device which you buy is Bluetooth compatible, Bluetooth compatible devices comes with software to configure Bluetooth to share data by implementing specific profiles, these profiles will determine what type of information or resources the device can store.
When you want two new Bluetooth device should communicate, first you have to introduce them to share data, this is known as pairing (authorizing the device to communicate with each other).
It is also possible to configure the devices to have password protection, so that other people cannot take part in your communication. One more thing is also there, you can set up the device to constantly announce their presence to the device in its range, and the connection can be automatically establish.
As this is the emerging technology today and is widely adopted by industry leaders, in every version new features are included, the next version of Bluetooth includes a number of features to increase security, usability and value of Bluetooth.
