From 1997 Г–rjan 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 (бљј, Hagall) and (б›’, Bjarkan), Harald's initials. It was the epithet of King Harald Bluetooth, who united the disparateДanish tribes into a single kingdom Kardach chose the name to imply that Bluetooth similarly unites communication protocols. Д«luetooth is the Anglicised version of the Scandinavian BlГҐtand/ BlГҐtann (or in Old Norse blГЎtЗ«nn).

Kardach was later quoted as saying, вЂњKing Harald BluetoothвЂ¦was famous for uniting Scandinavia just as we intended to unite the PC and cellular industries with a short-range wireless link.вЂќ 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 вЂњBluetoothвЂќ was proposed in 1997 by Jim Kardach of Intel, one of the founders of the Bluetooth SIG.

7.2.7 Audio/Video Control Transport Protocol.7.2.6 Bluetooth Network Encapsulation Protocol.7.2.3 Logical Link Control and Adaptation Protocol.By 2017, there were 3.6 billion Bluetooth devices shipping annually and the shipments were expected to continue increasing at about 12% a year. 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 10В meters (30В feet).Д«luetooth 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 Д«luetooth 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).
