Determining compliance based on the results of the compliance measurement, not taking into account measurement instrumentation uncertainty. 2. 2.4GHz: Directional gain = 0.12dBi + 10log(4) = 6.14dBi 5GHz: Directional gain = 0dBi + 10log(4) = 6.02dBi Conclusion: The formula of calculated the MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1 CPD = Calculation power density LPD = Limit of power density WLAN 2.4GHz + WLAN 5GHz = 0.44666 / 1 + 0.43177 / 1 = 0.87843 Therefore the maximum calculations of above situations are less than the “1” limit. --- END --- Report No.: SA190806E11 Page No. 7 / 7 Report Format Version: 6.1.1
