Power Antenna Gain Distance Power Density Limit 2 2 (MHz) (mW) (dBi) (cm) (mW/cm ) (mW/cm ) 2402-2480 5.875 3.13 30 0.00107 1 BT-LE Frequency Max. Power Antenna Gain Distance Power Density Limit 2 2 (MHz) (mW) (dBi) (cm) (mW/cm ) (mW/cm ) 2402-2480 1.73 3.13 30 0.00031 1 For Zigbee: Frequency Max. Power Antenna Gain Distance Power Density Limit 2 2 (MHz) (mW) (dBi) (cm) (mW/cm ) (mW/cm ) 2405-2475 144.544 2.52 30 0.02283 1 Report No.: SA160810E03D Page No. 7 / 8 Report Format Version: 6.1.1 Reference No.: 170125E10

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 (Radio 1) + WLAN 5GHz (Radio 2) + Bluetooth + Zigbee = 0.24693 / 1 + 0.33912 / 1 + 0.34185 / 1 + 0.00107 / 1 + 0.02283 / 1 = 0.95180 Therefore the maximum calculations of above situations are less than the “1” limit. --- END --- Report No.: SA160810E03D Page No. 8 / 8 Report Format Version: 6.1.1 Reference No.: 170125E10
