RF EXPOSURE EVALUATION METHOD

SAR Test Exclusion Thresholds for 100 MHz ~ 6 GHz and < 50 mm

Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation
Distances are illustrated in the following Table.

 The 1—g and 10— SAR test exclusion thresholds for 100 MHz to 6 GHz at test separetion
distances < 50 mm are determined by:
[{max. power of channel, including tune—up tolerance, mW)(min. test separation distance,
mm}] + [/#(GHz)] < 3.0 for 1—g SAR and < 7.5 for 10—g extremity SAR where
i(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
The test exclusions are applicable only when the minimum test separation distance is < 50
mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test
separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test
exclusion

Remark: The best case gain of the antenna is 0.5 dBi.
0.5 dBi logarithmic terms convert to numeric result is nearly 1
-6.908 dbm=0.204 mw


BT:
[(max. power of channel, including tune-up tolerance, mW)/(min. test separation
distance,mm)] · [√f(GHz)]= 0.204/5*√2.480≤3.0


Threshold at which no SAR required is 10mw and ≤ 3.0 for 1-g SAR, Separation
distance is 5mm.


Conclusion: No SAR is required.
