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 + Zigbee + Sub-GHz + Z-Wave = 0.56492 / 1 + 0.29766 / 1 + 0.03349 / 1 + 0.02157 / 0.61 + 0.00012 / 0.6056 = 0.93163 Therefore the maximum calculations of above situations are less than the “1” limit. --- END --- Report No.: SA180830E03C Page No. 8 / 8 Report Format Version: 6.1.1 Reference No.: 190213E03
