                                                               FCC ID: 2AHDSPS210-01
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

Field strength = 78.59dBuV/m @3m
Ant gain =0dBi, so Ant numeric gain= 1.0

So pt={ [10(78.59/20)/106 x 3]2/30x1.0 }x1000 mW = 0.022mW
So (0.022mW /5mm)x √2.476 = 0.007<3

Then SAR evaluation is not required
