February 6, 2009
The advancement in technology has made possible so many things, which otherwise would not be imaginable. Mobile phone is one such example of technology. A device that was initially used for wireless communication, mobile phones now have so many functionalities. You can play music, take snaps, listen to FM radio, play movies, surf the web, send emails, etc. You can also transfer files to other mobile phones and devices. Bluetooth, infrared and USB cables enable you to transfer data with ease.
File transfer via infrared has certain limitations like the line of sight must be free. Your infrared port should be pointed towards the other phone you wish to connect. Also it is point -to-point; communication is possible between only 2 devices at a time. Even USB cables have their own constraints. But there are no such constraints in Bluetooth and it outperforms both infrared and USB.
It is the era of multimedia mobile phones that incorporate a wide array of innovative and useful features in them. The minimum requirements to be called a multimedia mobile, it should have a camera, video playback, mp3 player, FM radio, 16-bit colour screen, WAP browser, Java, USB, Bluetooth etc. When you want to transfer files to other devices or share your images or send music files, Bluetooth is of great advantage.
Bluetooth is a wireless technology that allows mobile phones, computers and other devices to interact with each other over short distances. It is an economical way of exchanging information between devices. Its uses include sending photos from mobile, exchanging business cards, sending voice messages, satellite navigation using GPS, etc.
The name Bluetooth comes from the Danish Viking, King Blatand (English translation-Bluetooth), who united Norway and Denmark. Similarly, Bluetooth also tries to connect different devices. Bluetooth uses two ranges, one is class 2 radios – having a range of 10 metres to 30 feet and usually used in mobile phones. The other is class 1 radios – having a range of 100 mt to 30 ft and commonly used in industrial use.
Unlike infrared, Bluetooth devices need not be in line of sight, it just have to be within range of each other, say about 10 metres. Bluetooth works by using radio chips, making it totally cable free. To ensure security and prevent eavesdropping Bluetooth devices frequently change radio frequency and also these devices have individual ID and before they can exchange data you have to enter a PIN number to authorise the connection. It is an amazing form of wireless technology.
Apart from being wireless, affordable, energy efficient, it also stands out to have minimal interference, easy automation and universal standard. Bluetooth 2.0 enables high speed data transfer and reduces power consumption by about half and is a cheaper proposition than wifi. Bluetooth is amazing technology that is convenient to use, economical and above all, very useful.
The advantages of Bluetooth technology can be summed up as cable and clutter free, unlike infrared no need of line of sight, worldwide compatible, secure connection, open platform and is popular worldwide because of the outstanding convenience and satisfaction it offers.
