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 distancesİ 5 mm are determined by:
[(max. power of channel, including tune-up tolerance, mW)/(min. test
separation distance, mm)] g[Ĝf(GHz)] İ 3.0 for 1-g SAR and İ 7.5 for
10-g extremity SAR, where
ǂf(GHz) is the RF channel transmit frequency in GHz
ǂ Power and distance are rounded to the nearest mW and mm before
calculation
ǂ 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
Sopt = (EXd)2/30 x gt

Field strength =97.7dBuV/m @3m
Ant gain =3.85dBi;so Ant numeric gain=2.427

So pt={ [10(97.7/20)/106 x3]2/30}x1000
（30X2.427）}x1000 mW =0.728mW
mW =1.767mW
So
So (0.728mW/5mm)x
(1.767mW/5mm)x Ĝ2.475GHz =0.55<3
0.23
=0.555<3

Then SAR evaluation is not required
