Bluetooth technology allows for short-range wireless connectivity between devices like mobile phones, laptops, and other portable devices. It uses a radio transmitter in each device operating in the unlicensed 2.4GHz radio band to connect over short distances of around 10 meters. The Bluetooth specifications define protocols for authentication, encryption, and how devices discover and connect with each other to exchange data wirelessly.
