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 İ 50 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

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

92.88 dBuV/m @3m
Field strength =89.46
Ant gain 0 dBi; so Ant numeric gain=1

(89.46/20)
So pt={[10(92.88/20) 0.265 mW
/106 x3]2/30x1 }x1000 mW =0.582
0.265 mW/5mm)x √2.402 GHz = 0.180
So (0.582 0.08 <3

Then SAR evaluation is not required
