Introduction Bluetooth® is a technology specifi cation designed for low-cost short-range radio communications between devices such as PCs, mobile phones, and other portable devices. On top of that, Bluetooth enables your devices to access the Internet. Originally developed in Scandinavia, this technology that unites products has a code name that is inspired by a 10th century Danish Viking king, Harald Bluetooth, who united and controlled Denmark and Norway during an era when Scandinavian Europe was torn apart by wars and feuding clans. Today, Bluetooth is administered by the Bluetooth Special Interest Group (SIG), whose members are leaders in the telecommunications, computing, networking, industrial automation, and automotive industries.
