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 7.024 5.0396 0.00100 1.0 PASS 802.11g 6.218 4.1860 0.00083 1.0 PASS 802.11n HT20 6.767 4.7501 0.00094 1.0 PASS 802.11n HT40 6.875 4.8697 0.00097 1.0 PASS Remark: antenna gain=0dBi For BT Field strength (dBuV/m) EIRP (dBm) Max tune-up (mW) Power Density at R=20cm (mW/cm 2 ) Limit (mW/cm 2 ) Result 84.66 -10.5 0.0891 0.00002 1.0 PASS Remark: antenna gain=0dBi For Simultaneous transmitting, 1): The sum of the ratios of the spatially averaged results to the applicable frequency dependent MPE limits =0.00100/1 + 0.00002/1 = 0.00102< 1 Since the sum of the MPE ratios for all simultaneously transmitting antennas incorporated in the device is ≤ 1.0, the EUT is considered to satisfy MPE compliance for simultaneous transmission operations.
