What is Bluetooth?

Bluetooth is a wireless networking technology designed primarily to replace cables for communication between personal computing and communication devices. It is intended to be used for both voice and data communications.

Why is it called Bluetooth?

The Bluetooth name refers to King Harald "Bluetooth" Blaatand, a famous Danish king of the 10th century, who unified Denmark and Norway. In the beginning of the Bluetooth wireless technology era, Bluetooth was aimed at unifying the telecom and computing industries.

When two devices need to talk to each other, they need to have a handshake on various parameters before the conversation starts. The first agreement is on the medium – will they use wires, or talk over some wireless signal? Bluetooth is one such wireless signal (protocol) over which two (or more) devices communicate over.

Strange name though isn’t it – are the bluetooth waves invisible but blue and shaped like teeth? Wrong! There is absolutely no relation between the name and the meaning.

The Bluetooth protocol was created by Ericsson (pre-Sony Ericsson) which is a major Swedish telecommunication company. They named it after the Danish viking king, Harald Blåtand. As legend goes, Blåtandhad the blessed ability to bring people negotiate with each other, and cometo talking terms. So skilled was he, that he was able to unite Denmark and Norway together! The literal translation of Blåtand means blue-tooth, hence the name Bluetooth for the protocol. It does precisely what Blåtand did – lets two wireless device to communicate with each other!
