Note:
1. Per Bluetooth Core_5.0, Vol.6 Part A, Section 3.2.2, exceptions are allowed in up to three bands of 1 MHz width, centered on a
frequency which is an integer multiple of 1 MHz. These exceptions shall have an absolute value of -20 dBm or less.
2. For 2476 MHz, 1.5 dB of power backoff is used to achieve this value.
3. For 2478 MHz, 4.2 dB of power backoff is used to achieve this value.
