Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz[2]) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994,[3] it was originally conceived as a wireless alternative to RS-232 data cables. It

Bluetooth logo
The word "Bluetooth" is an anglicized version of the Scandinavian Blåtand/Blåtann, (Old Norse blátonn) the epithet of the tenth-century king Harald Bluetooth who united dissonant Danish tribes into a single kingdom, according to legend, introducing Christianity as well. The idea of this name was proposed in 1997 by Jim Kardach who developed a system that would allow mobile phones to communicate with computers. At the time of this proposal he was reading Frans Gunnar Bengtsson's historical novel The Long Ships about Vikings and king Harald Bluetooth.[7][8] The implication is that Bluetooth does the same with communications protocols, uniting them into one universal standard.[9][10][11]
The Bluetooth logo is a bind rune merging the Younger Futhark runes (Hagall) (?) and (Bjarkan) (?), Harald's initials.
