To comply with the MPE, the fraction of the MPE in terms of E 2 , H 2 (or power density) incurred within each frequency interval should be determined and the sum of all such fractions should not exceed unity. In order to ensure compliance with the MPE for a controlled environment, the sum of the ratios of the power density to the corresponding MPE should not exceed unity. That is Note: The BLE/WIFI 2.4G/WIFI 5G share the same ANT cannot transmit at same time.
