Bluetooth is a short-range wireless standard for connecting nearby devices such as phones, computers, earphones and keyboards without cables. It operates in the 2.4 GHz radio band. Ericsson began developing the technology in the 1990s, and the specification is now managed by the Bluetooth Special Interest Group (SIG).

Bluetooth Low Energy (BLE), a variant designed for much lower power consumption, is widely used in wearables, sensors and small input devices that need to run on batteries for long periods.
