Blue tooth
King Harald Bluetooth ruled Denmark between 940 and 985 A.D. Bluetooth was actually “BlÃ¥tand” in old Viking language, which meant “dark complexion” – he had unusually dark hair for a Viking. His legacy was that he united Denmark and Norway and also brought Christianity to Scan-dinavia.
He left a large monument, the Jelling rune stone, in memory of his parents. He was killed in 986 during a battle with his son, Svend Forkbeard.
Choosing this name for the standard indicates how important companies from the Nordic region (nations including Denmark, Sweden, Norway and Finland) are to the communications industry, even if it says little about the way the technology works.
Ericsson hoped that the technology that bears Bluetooth’s name would similarly “unite” electronic devices everywhere by wireless technology-Personal area network
