RF exposure letter 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 ʇ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ș[ɰf(GHz)] ʇ 3.0 for 1-g SAR and ʇ 7.5 for 10-g extremity SAR, where ș f(GHz) is the RF channel transmit frequency in GHz ș Power and distance are rounded to the nearest mW and mm before calculation ș The result is rounded to one decimal place for comparison Worse case is as below: [2480 MHz 0 dBmͧ1 mWͨ output power] (1mW /5mm) ș[ɰ2.441(GHz)]=0.3150 <3.0 for 1-g SAR Then SAR evaluation is not required 2441MHz -0.11dBm0.975mW
