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 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. History Įricsson Bluetooth module PBA 313 01/2S R2A manufactured in week 22, 2001. 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). The name caught on fast and before it could be changed, it spread throughout the industry, becoming synonymous with short-range wireless technology.

PAN was the front runner, but an exhaustive search discovered it already had tens of thousands of hits throughout the internet.Ī full trademark search on RadioWire couldn't be completed in time for launch, making Bluetooth the only choice. Later, when it came time to select a serious name, Bluetooth was to be replaced with either RadioWire or PAN (Personal Area Networking). Īccording to Bluetooth's official website,īluetooth was only intended as a placeholder until marketing could come up with something really cool. Upon discovering a picture of the runestone of Harald Bluetooth in the book A History of the Vikings by Gwyn Jones, 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. 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.In 2021, shipments reached 4.7 billion units, with 9% growth forecast. By 2017, there were 3.6 billion Bluetooth devices being shipped 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 10 metres (33 ft).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 employs UHF radio waves in the ISM bands, from 2.402 GHz to 2.48 GHz. 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 and building personal area networks (PANs).
