Bluetooth data transmission occurs within which frequency band?

Bluetooth transmissions occur in the 2.4 GHz ISM band, a globally available unlicensed frequency range ideal for short-range wireless connections. It uses roughly 2.402 GHz up to about 2.480–2.485 GHz, with many 1 MHz channels and hopping across them to reduce interference from other devices sharing the same band. This shared, low-power spectrum is why Bluetooth can operate alongside Wi‑Fi and other gadgets without needing licenses. The other suggested ranges extend above this band, so they aren’t used for Bluetooth.
