HISTORY OF Bluetooth

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 telecommunicati

on 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!
The Bluetooth symbol has
HaraldBlåtand’s initials inscribed into it (in Runic).
The two lines stickingout of the back of the B actually represent a Runic H – thats
H for Harald .The B for Bluetooth also stands for Blåtand!
