Bluetooth is an industrial specification for wireless personal area networks (PANs), also known as IEEE 802.15.1. Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers, digital cameras and video game consoles such as the Nintendo Wii and Sony PlayStation 3 via a secure, globally unlicensed short range radio frequency.

The name Bluetooth is derived from the cognomen of a 10th century king of Denmark, Harald Bluetooth. According to the inventors of the Bluetooth technology, Harald engaged in diplomacy which led warring parties to negotiate with each other, making Bluetooth a fitting name for their technology, which allows different devices to talk to each other. The name of the king in Danish is Harald Blåtand and the Bluetooth logo is based on the H and B runes ( The Runic Alphabets are a set of related alphabets using letters known as runes, formerly used to write Germanic languages, mainly in Scandinavia and the British Isles, but before Christianization also on the European Continent ).

Bluetooth is a radio standard and communications protocol primarily designed for low power consumption, with a short range (power class dependent: 1 meter, 10 meters, 100 meters) based around low-cost transceiver microchips in each device. ad Bluetooth lets these devices communicate with each other when they are in range. The devices use a radio communications system, so they do not have to be in line of sight of each other, and can even be in other rooms, so long as the received power is high enough. As a result of different antenna designs, transmission path attenuations, and other variables, observed ranges are variable.
