History


In ' 94, the Ericsson telecommunications company undertook a study of viability of an interface between mobile phones and accessories with a low cost.

In early 97, Ericsson joined other manufacturers of portable devices to increase the diffusion of this technology. This system was to be used by a sufficient amount of portable devices.
In February 98, five companies, Ericsson, Nokia, IBM, Toshiba and Intel, founded a special interest group (SIG). This group was a good mix :
two of the market leaders in mobile telephony, two leaders of the market for portable computers and a market leader in digital signal processing technology.

The goal was the creation of a global specification for connectivity short range wireless. 20 and 21 May 98, the Bluetooth consortium is announced to the public in London, San Jose and Tokyo.

The Bluetooth name


The explanation on the origin of the name and symbol of Bluetooth technology are interesting :

It comes from a King who owned a blue tooth : Harald Bluetooth 1.
Harald 1 Bluetooth was King of the Denmark. It nicknamed \blue tooth\ due to illness which give this colouring to his prosthesis.

He was born in 910, he is son of the Grom the old King. Like many Vikings, Harald decided to fight for the riches abroad. When Harald's sister, Gunhild was widowed after the violent death of the Norwegian King Erik, she came to the Denmark to seek the assistance of Harald and control of the Norway. Harald took the opportunity to take power himself.

In 960, he was at the height of his glory, he ruled the Denmark and the Norway. He was baptized by a priest named Poppo and sent by the German Emperor. He then erected a monument on which is engraved : this monument to the memory of his father Grom and Thyra his mother King Harald.
Harald conquered all the Denmark and the Norway and made the Danes Christians, he was killed in a battle in 985.

The Bluetooth logo combines in the same symbol, the representation of 2 Nordic runes Hagalaz (H) and Berkana (B).
Today the Bluetooth symbol is as famous as the name. Everyone accepts the symbol as the icon of Bluetooth technology, few are those who know the origin.
