The frequency band of Bluetooth is 2400-2483.5MHz (including protected band). This is a 2.4 GHz short-range radio band in the Industrial, Scientific, and Medical (ISM) band, which is unlicensed (but not unregulated) worldwide.
Utilizing Bluetooth frequency hopping technology, the transmitted data is divided into packets and transmitted over each of 79 designated Bluetooth channels. Each channel has a bandwidth of 1 MHz. Bluetooth 4.0 uses 2 MHz spacing and can accommodate 40 channels. The first channel starts at 2402 MHz and there is one channel for every 1 MHz up to 2480 MHz. With Adaptive Frequency Hopping (AFH), it typically hops 1600 times per second.
