Bluetooth technology is named after the 10th-century Danish king Harald Bluetooth, whose runic initials inspired the Bluetooth logo. Bluetooth allows wireless transmission of voice and data between devices using short-range radio signals in the 2.4 GHz band, enabling cable-free connections between mobile phones, laptops, headphones, and other devices. It facilitates the synchronization of data and eliminates the need for cables by offering small wireless networks to connect digital equipment.
