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 = 96.36 dBuV/m @3m
Ant gain =2dBi, so Ant numeric gain= 1.58

                                                    0.82
So pt={ [10(96.36/20)/106 x 3]2/30x1.58 }x1000 mW = 0.819mW
    0.82 mW /5mm)x √2.48 = 0.258<3
So (0.819                            0.26

Then SAR evaluation is not required
