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 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 2437 21.43 139.0 0.07 1.0 PASS Remark: antenna gain=3.89dBi
