2.1 Calculation Result of Maximum Conducted Power Frequency Band Max Power Antenna Gain Distance Power Density Limit 2 2 (MHz) (mW) (dBi) (cm) (mW/cm ) (mW/cm ) 2412-2462 409.643 8.62 32 0.23168 1 5180-5240 431.54 10.71 32 0.39492 1 5745-5825 715.803 10.55 32 0.63137 1 NOTE: G0/20 G1/20 G3/20 2 2.4GHz: Directional gain =10 log[(10 + 10 + 10 ) / 3] = 8.62dBi 5 GHz: G0/20 G1/20 G2/20 G3/20 2 UNII-1: Directional gain = 10 log[(10 + 10 + 10 + 10 ) / 4] = 10.71dBi G0/20 G1/20 G2/20 G3/20 2 UNII-3: Directional gain = 10 log[(10 + 10 + 10 + 10 ) / 4] = 10.55dBi 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 = 0.23168 / 1 + 0.63137 / 1 = 0.86305 Therefore the maximum calculations of above situations are less than the “1” limit. --- END --- Report No.: SA170320E01B Page No. 8 / 8 Report Format Version: 6.1.1 Reference No.:170807E04
