Conclusion: The formula of calculated the MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1 CPD = Calculation power density LPD = Limit of power density BT-LE + 5G NR n261 + WWAN (CA_B13A_ANT 0) + WWAN (CA_B66A_ANT 2) = 0.0037 / 1 + 0.07059 / 1 + 0.17168 / 0.5197 + 0.20125 / 1 = 0.60588 BT-LE + 5G NR n260 + WWAN (CA_B13A_ANT 0) + WWAN (CA_B66A_ANT 2) = 0.0037 / 1 + 0.04454 / 1 + 0.17168 / 0.5197 + 0.20125 / 1 = 0.57983 Therefore the maximum calculations of above situations are less than the “1” limit. --- END --- Report No.: SA190401E07 Page No. 8 / 8 Report Format Version: 6.1.1
