FCC ID: RDR-QY19 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 eirp = pt x gt = (EXd)2/30 where: pt = transmitter output power in watts, gt = numeric gain of the transmitting antenna (unitless), E = electric field strength in V/m, --- 10((dBuV/m)/20)/106 d = measurement distance in meters (m) ---3m So pt = (EXd)2/30 x gt Field strength = 96.91dBuV/m @3m Ant gain =2.5dBi, so Ant numeric gain= 1.78 So pt={ [1096.91/20)/106 x 3]2/30x1.78 }x1000 mW = 0.828mW So (0.828mW /5mm)x √2.480 = 0.261<3 Then SAR evaluation is not required
