2. RF Exposure evaluation for FCC
According to 447498 D01 General RF Exposure Guidance v06
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: [2441MHz, -2.02dBm (0.63mW) output power]
(0.63/5) ·[√2.441(GHz)] = 0.197<3.0 for 1-g SAR
Then SAR evaluation is not required
