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=-8dBi ; so numerical antenna gain=0.158
Field strength =
So pt ={
78.39dBuV/m @3m
[10(78.39/20)/106
x3]2/ 30X0.158
}x1000
So ( 0.131 mW/5mm)x √0.418 GHz =0.017 < 3
= 0.131 mW
