Bluetooth is a wireless technology standard that allows short-range wireless connections between devices like mobile phones, laptops, and other portable devices. It uses a radio transmitter in each device operating in the unlicensed 2.4GHz band to connect devices within a range of about 10 meters. The Bluetooth specifications include protocols for networking, security, and interoperability between various Bluetooth devices. Some key uses of Bluetooth technology include wireless connectivity between mobile phones, laptops, and peripherals to replace cables, wireless networking between devices, and data/voice access over ad-hoc networks.
