Nowadays, mobile phones serve more than just the purpose of making and receiving calls. It offers many features such as MMS, SMS, etc. With such developments there have also been many allied developments in technology, which complement these features. One such development is the Bluetooth.
An interesting fact about how Bluetooth derived its name, according to the records is that, a Denmark King was by the name Harald Bluetooth. When his kingdom had to wage war with another kingdom, he played a very diplomatic role and made the two parties to negotiate. So, this makes Bluetooth a fitting name for the device, as it serves in the middle for the communication between other devices.
Bluetooth is a wireless form of Personal Area Networking. That it helps in the communication between devices such as computer and mobile phones, which are close to one person. Information can be exchanged between, computers, laptops, cell phones, digital cameras etc. For the functioning, the Bluetooth uses radio communications system. The distance in which the transmission can take place depends on the power of the device. Based on the power, the devices are classified into classes:
· Class 1: The range is 100 meters.
· Class 2: The range is 10 meters.
· Class 3: The range is 1 meter.
Though most of the uses of the Bluetooth are concerned with PCs, as with mobile phones, they are used for communication between the phones and hands free headset. The device is used between two devices, which do not require much bandwidth for communication. The main requirement of a personal computer, in order to use a Bluetooth is the presence of Bluetooth adaptor. It is only in the presence of this that the computer can communicate with other devices such as mobile phones, through the Bluetooth. Windows XP is the modern day operating system which supports Bluetooth.
There are many versions of the Bluetooth that have been developed:
· The very first versions of Bluetooth were, 1.0 and 1.0B. These had many problems.
· The next version was 1.1, this had all the corrections of the problems which the other versions held.
· The third version was 1.2; this was compatible with 1.1 and had several advantages such as better adaptation, faster connection, and higher transmission rates.
· The later versions were 2.0 and 2.1, which have much higher transmission rates and many more extra features, making it a very high end device.
The future versions of Bluetooth are expected to serve many more purposes and aid in the transfer of large amounts of data, such as high quality audio, video for portable projectors, TVs etc.
