Bluetooth, operating in 2.4 GHz ISM band, employs 79 RF channels with 1 MHz spacing for Basic and Enhanced Data Rates (BR/EDR) transmissions and 40 RF channels with 2 MHz spacing for Low Energy (LE) transmissions. Each RF channel is ordered in channel number k as follows: f=2402+k MHz, k=0,…,78 (BR/EDR) and f=2402+k*2 MHz, k=0, … ,39 (LE).
