Bluetooth is a short-range wireless standard for exchanging data and building personal area networks (PANs) over the 2.4 GHz ISM band.
Bluetooth is a short-range wireless technology standard used to exchange data between nearby fixed and mobile devices and to form personal area networks (PANs). It operates in the unlicensed 2.4 GHz ISM band (about 2.402–2.48 GHz) and is designed as a convenient alternative to wired connections, typically with very low power for short distances (often up to around 10 m in common use, with longer ranges possible depending on conditions and Bluetooth version). Typical use cases include connecting phones and music players to wireless audio devices such as headphones, earbuds, speakers, car audio systems, and TV/soundbar setups. Bluetooth is also widely used for low-power device connectivity in areas like wearables and smart home systems, as well as for peripherals and data exchange between nearby devices (e.g., PCs, gaming accessories, and other embedded devices).
