Bluetooth is wireless communication interface which allows electronic devices to connect and interact with each other. It doesn’t rely on Wi-Fi, or mobile data or a cell network It can be found in a number of gadgets, from smartphones, to loudspeakers, to laptops and more.
The “Bluetooth” name is taken from a 10th-century Danish king named Harald Bluetooth, who was said to unite disparate, warring regional factions. Like its namesake, Bluetooth technology brings together a broad range of devices across many different industries through a unifying communication standard.
The Bluetooth technology can be a drain on battery power for mobile wireless devices like smartphones. Also, the range is fairly limited, usually extending only about 30 feet.
