Ericsson contributed the short-link radio technology, and IBM contributed patents around the logical layer. Since neither IBM ThinkPad notebooks nor Ericsson phones were the market share leaders in their respective markets at that time, Adalio Sanchez and Nils Rydbeck agreed to make the short-link technology an open industry standard to permit each player maximum market access. Instead, the two companies agreed to integrate Ericsson's short-link technology on both a ThinkPad notebook and an Ericsson phone to accomplish the goal.

The conclusion was that power consumption on cellphone technology at that time was too high to allow viable integration into a notebook and still achieve adequate battery life. The two assigned engineers from Ericsson and IBM to study the idea. In 1997, Adalio Sanchez, then head of IBM ThinkPad product R&D, approached Nils Rydbeck about collaborating on integrating a mobile phone into a ThinkPad notebook. From 1997 Г–rjan Johansson became the project leader and propelled the technology and standardization. In 1990, Jaap Haartsen was nominated by the European Patent Office for the European Inventor Award. 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 disparateДanish tribes into a single kingdom, the implication being that Bluetooth unites communication protocols. Д«luetooth is the Anglicised version of the Scandinavian BlГҐtand/ BlГҐtann (or in Old Norse blГЎtЗ«nn). Bengtsson's historical novel The Long Ships about Vikings and the 10th-century Danish king Harald Bluetooth. At the time of this proposal, he was reading Frans G. The name вЂњBluetoothвЂќ was proposed in 1997 by Jim Kardach of Intel. 7.2.8 Audio/Video Distribution Transport Protocol.7.2.7 Audio/Video Control Transport Protocol.7.2.6 Bluetooth Network Encapsulation Protocol.7.2.3 Logical Link Control and Adaptation Protocol.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).
