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). Upon discovering a picture of the Harald Bluetooth rune stone in the book Gwyn Jones's 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.
As of 2009, Bluetooth integrated circuit chips ship approximately 920 million units annually.
A network of patents apply to the technology, which are licensed to individual qualifying devices. A manufacturer must meet Bluetooth SIG standards to market it as a Bluetooth device. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard. In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 meters (30 feet).īluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics.
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. More than a kilometer, Less than a meter 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).
