Bluetooth uses low power radio waves in the frequency range of:

Bluetooth uses low power radio waves in the 2.4 GHz ISM band, a globally available unlicensed spectrum ideal for short-range wireless communication. The frequency range is about 2.4 to 2.485 GHz, which places it in gigahertz, not in hertz, megahertz, or terahertz. The other options fall outside the actual Bluetooth band, so they wouldn’t support this technology. This 2.4 GHz band is chosen to balance range, power consumption, and interoperability across devices worldwide.
