FCC ID: 2AAD8-U1233 RF Exposure evaluation According to 447498 D01 General RF Exposure Guidance v05 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where f(GHz) is the RF channel transmit frequency in GHz. Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison Worse case is as below: Antenna RF output power SAR Test SAR Test Mode f (GHz) Distance Exclusion dBm mW Exclusion (mm) Threshold 2.4G WLAN 2.452 5 6.33 4.30 1.35 < 3.0 Yes (MIMO) 5G WLAN 5.200 5 5.70 3.72 1.69 < 3.0 Yes (MIMO) 2.4G (ANT1) 2.412 5 4.187 2.62 0.81 < 3.0 Yes 2.4G (ANT2) 2.462 5 3.423 2.20 0.69 < 3.0 Yes 5G (ANT1) 5.200 5 3.204 2.09 0.95 < 3.0 Yes 5G (ANT2) 5.200 5 3.155 2.07 0.94 < 3.0 Yes Maximum Simultaneous transmission MPE Ratios for 2.4GHz WLAN and 5G WLAN Maximum MPE Maximum MPE ∑MPE Mode Limit Results ratio 2.4GWLAN ratio 5GWLAN ratios 2.4G(ANT1)+5G(ANT2) 0.81 0.94 1.75 3.0 PASS 2.4G(ANT2)+5G(ANT1) 0.69 0.95 1.64 3.0 PASS The device 2.4G WLAN use 2T2R MIMO technology, 5GWLAN use 2T2R MIMO technology, but does not support 2.4G WIFI and 5G WIFI simultaneous transmission on the same antenna. Then SAR evaluation is not required.
