From 1997 Örjan Johansson became the project leader and propelled the technology and standardization.
Principal design and development began in 1994 and by 1997 the team had a workable solution. Nils Rydbeck tasked Tord Wingren with specifying and Dutchman Jaap Haartsen and Sven Mattisson with developing. The purpose was to develop wireless headsets, according to two inventions by Johan Ullman, SE 8902098-6, issued and SE 9202239, issued. The development of the "short-link" radio technology, later named Bluetooth, was initiated in 1989 by Nils Rydbeck, CTO at Ericsson Mobile in Lund, Sweden. The Bluetooth logo is a bind rune merging the Younger Futhark runes (ᚼ, Hagall) and (ᛒ, Bjarkan), Harald's initials. It was the epithet of King Harald Bluetooth, who united the disparateĭanish tribes into a single kingdom Kardach chose the name to imply that Bluetooth similarly unites communication protocols. īluetooth is the Anglicised version of the Scandinavian Blåtand/ Blåtann (or in Old Norse blátǫnn).

Kardach was later quoted as saying, “King Harald Bluetooth…was famous for uniting Scandinavia just as we intended to unite the PC and cellular industries with a short-range wireless link.” Bluetooth was only intended as a placeholder until marketing could come up with something really cool. Upon discovering a picture of the Harald Bluetooth rune stone in the book Gwyn Jones's A History of the Vikings, Jim proposed Bluetooth as the codename for the short-range wireless program which is now called Bluetooth. Bengtsson's The Long Ships, a historical novel about Vikings and the 10th-century Danish king Harald Bluetooth. The name was inspired by a conversation with Sven Mattisson who related Scandinavian history through tales from Frans G. The name “Bluetooth” was proposed in 1997 by Jim Kardach of Intel, one of the founders of the Bluetooth SIG.

It is mainly used as an alternative to wire connections, to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones. It was originally conceived as a wireless alternative to RS-232 data cables. Typically less than 10 m (33 ft), up to 100 m (330 ft).īluetooth 5.0: 40–400 m (100–1,000 ft) īluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances using UHF radio waves in the ISM bands, from 2.402 GHz to 2.48 GHz, and building personal area networks (PANs).
