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 2021, 4.7 billion Bluetooth integrated circuit chips are shipped 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. 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.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 employs UHF radio waves in the ISM bands, from 2.402 GHz to 2.48 GHz. 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). 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).
