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
So pt = (EXd)2/30 x gt
Antenna gain= 0dBi ; so numerical antenna gain= 1
Field strength =79.02 dBuV/m @3m
So pt ={ [10(79.02
/20)
/106 x3]2/30X1}x1000 = 0.024mW
So ( 0.024mW/5mm)x √0.31385 GHz =0.0027 < 3
