Problems arise when you start to connect devices to a computer with a lot of cables.
BlueTooth aims to eliminate these cables.
Bluetooth is a universal device, it is valid for connecting all kinds of devices, and works transparently for the user.
In ' 94, the telecommunications company ERICSSON, undertook a study of viability of an interface low cost between mobile phones and accessories.
The goal was to eliminate cables between phones mobiles and cards for computers, headphones, desktops, etc.
In early 97,. Ericsson closing other manufacturers of portable devices in order to increase the interest in this technology.
The reason is simple : so that the system is successful and really usable, a sufficient amount of portable devices must use the same technology.
In February 98, five companies, Ericsson, Nokia, IBM, Toshiba and Intelfounded a special interest group (SIG).
This group is a perfect 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 to establish 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 (England), San Jose (California) and Tokyo (Japan).
This global announcement causes the adoption of technology to several companies. The consortium intended to establish a standard device with software.
Before going into technical details, it is interesting to give an explanation on the origin of the name and symbol of the technology BlueTooth. Everyone has a cell phone with BlueTooth, few people know where come the symbol
The name Bluetooth
Someone who owns a blue tooth ? Yes, the name comes from a King, Harald 1 BlueTooth :
Harald 1 BlueTooth(Danish Harald Blåtand) was King of Denmark between 40 and 85.
The name Blåtand probably comes from two old Danish words, blå flayed and great man tan.
The name BlueTooth comes from the tenth century, the King Harald II of Denmark, was dubbed \blue tooth\ due to illness which give this colouring to his prosthesis.
He was born in 910, he is son of the King Grom the old man (King's) Jutland(, the main peninsula of the Denmark) and Thyre Danebold (daughter of the King Ethelred in England). Like many Vikings. Harald has seen fit to fight for the riches abroad.
When the sister of Harald, Gunhild was widowed after the violent death of the Norwegian King Erik , she came to the Denmark to ask for the help of Harald to ensure control of the Norway. Harald took the opportunity to take control himself.
In 960, he was at the height of his powers, he ruled the Denmark and the Norway. He was baptized by a priest named Popposent by the German Emperor.
He then erected a monument on which is engraved : \\The King Harald student this monument to the memory of his father Grom et de ThyraHis mother. Harald has conquered the Denmark and the Norway and made the Danes a chretien\\.
These words were also carved in runic stones.
Harald was killed in a battle in 985.
Harald had completed the unification of the country, begun by his father, converted the Danes to Christianity and conquered Norway. The expansion begun by Harald of Norway was continued by his son Sven Iwho conquered England in 1013.
During the reign of the son of Sven, Canutea great Kingdom Anglo-Scandinavian was born that included part of the Sweden.
Harald has thus reunified under his rule many small kingdoms that existed in the Denmark and Norway and worked with different rules...
the same thing as technology BlueToothpromoted by Ericsson (Sweden) and Nokia (Finland), two Scandinavian countries.
The symbol of BlueTooth is as famous as the name. Everyone accepts this symbol as a BlueTooth icon, but again, few are those who know the origin.
The logo of BlueTooth combines the representation of Nordic runes Hagalaz (transcribed by) H) and Berkana (transcrit par B) dans le même symbole.
It's, HB as the King Harald Blåtand .
