Bluetooth uses the 2.4 to 2.485 GHz frequency band for transmitting data between devices wirelessly, sharing the ISM band with other technologies like WiFi.
Bluetooth technology is designed to transmit data over a specific frequency band. It operates within the globally unlicensed Industrial, Scientific and Medical (ISM) 2.4 GHz short-range radio frequency band. The correct frequency range for Bluetooth is 2.4 to 2.485 GHz. This range allows devices to communicate with each other without the need for cables or wires, using a spectrum shared with other technologies like WiFi, which operates at 2.4 to 5 GHz, and microwave ovens with a frequency close to 2.45 GHz.
