The technology of Bluetooth allows two electronic devices to communicate wirelessly. Such devices can be computers, mobile phones, printers, MP3 players, PDAs etc. Most of the device communications use cables but today wireless communication has emerged and Bluetooth is one of these technologies.
The name of Bluetooth was inspired from Harald Bluetooth, he was the king of Denmark in the late 900s. He was awarded for many of his efforts including making peace between Denmark and Norway and the introduction of Christianity. Bluetooth got its name from this king to show the importance of communication.
Technical obstacles are present that does not make it easy to bring various devices together. The physical means of communication like use of cables, radio waves and infrared are the first concern in making two devices communicate. Secondly, the two devices must have the ability to speak the same language.
Bluetooth has a wireless technology. Two devices in the surrounding area can communicate with each other at higher speeds. For the Bluetooth to enable communication between devices, these devices should also have Bluetooth technology added in its features.
Bluetooth does not only allow wireless communication between devices, human intervention is also not needed to make such communication happen. This means that when Bluetooth devices come to each other in the surrounding area, they will automatically recognize each other and start sending data.
A digital camera is a good example of Bluetooth, it can transmit files to a Bluetooth enabled photo printer. Bluetooth technology is also available in mobile phones, it can pick up phone calls when you are on the move and reroute the calls to your car's audio system so you can talk on the phone without using hands.
Initially, Bluetooth was designed for mobile phone users. Because of mobile technology, it is small and light weighted. It is also not very expensive and its price is less than 50 dollars.
The device contains instructions for communications. It has a small power usage. The distance allowing communication between the two devices is usually within 3 meters to 10 feet. For more energy and communication with another device up to 30 feet in diameter, stronger versions are being introduced. The signals of Bluetooth can communicate at the frequency of 2.45 GHz which is greater than normal TV and radio waves.
With this advent of technology, security is also an important issue because this technology allows the device to communicate with any other detected device. There is also a possibility that the files located on the device with the technology can be damaged and corrupted in even of hacking and virus attacks. It is important that the user should understand the security features making it safe for use.
