If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. EIRP=EMeas+20log(dMeas)-104.7 EIRP is the equivalent isotropically radiated power, in dBm EMeas is the field strength of the emission at the measurement distance, in dBμV/m dMeas is the measurement distance, in m Test Result of RF Exposure Evaluation wifi 2.4G mode Channel Output power to antenna (dBm) Output power to antenna (mW) Power Density at R=20cm (mW/cm 2 ) Limit (mW/cm 2 ) Result 802.11b 13.70 23.4423 0.00456 1.0 PASS 802.11g 14.23 26.4850 0.00515 1.0 PASS 802.11n HT20 13.97 24.9459 0.00485 1.0 PASS 802.11n HT40 11.78 15.0661 0.00293 1.0 PASS Remark: antenna gain=-0.1dBi wifi 5G mode: Band Channel Output power to antenna (dBm) Output power to antenna (mW) Power Density at R=20cm (mW/cm 2 ) Limit (mW/cm 2 ) Result Band 1 802.11a 14.56 28.5759 0.00905 1.0 PASS 802.11n HT20 13.951 24.8370 0.00787 1.0 PASS 802.11n HT40 14.999 31.6155 0.01001 1.0 PASS Band Channel Output power to antenna (dBm) Ou…
