                           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≤ 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
Sopt = (EXd)2/30 x gt


Ant gain=0 dBi ;so Ant numeric gain= 1


Field strength =96.99 dBuV/m @3m

So Pt={ [10(96.99   /20)
                        /106 x3]2/30x1 }x1000 mW = 1.5 mW

So ( 1.5 mW/5mm)x √2.440 GHz =0.5     < 3



Then SAR evaluation is not required
