Bluetooth is a method of communication for sending and receiving information such as messages, files and data within short range of distance.  Initially the Bluetooth technology was used in the place of RS232 data cables. The transmission through this technology is possible within hundred meters of distance between two devices. The transmission beyond this distance is not possible. The Bluetooth technology is widely spread among the people in this world. The mobile technology has made the Bluetooth technology very familiar among the people. Frequency-hopping spectrum is the principle applied in this technology. The frequency-hopping spectrum is a radio technology. It disintegrates the data to be transmitted before transmission so that the data can be sent as many parts. Bluetooth technology can be used by Bluetooth enabled devices to transmit data. The important application is mobile phone. The laptops and personal computers can also have Bluetooth facilities to transmit data to other Bluetooth devices. The power consumed by the Bluetooth technology is not very high. The rate of transmission of data is much faster when compared to copying data to a memory card from a personal computer. So the time consumption is also very less for this technology. This is why people prefer Bluetooth over data cables.
