Bluetooth is a wireless standard that allows secure connections between devices over short distances using radio transmissions. It operates on the industrial, scientific and medical band, which is unlicensed and available in most countries at 2.4 to 2.485 gigahertz.
As of 2014, billions of products and devices, including cell phones, vehicles, medical devices, computers and toothbrushes, come with integrated Bluetooth wireless technology. It is a combination of software and hardware that allows users to share data, photos, music, videos and other information between paired Bluetooth-enabled devices. Engineers at Ericsson first invented the technology in 1994. In 1998, Ericsson, Nokia, Intel, IBM and Toshiba formed the Bluetooth Special Interest Group to develop the technology further; no single company owns Bluetooth.
