RF Exposure Evaluation
According to KDB 447498 and part 2.1093,Unless specifically required by the published
RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR
evaluation for general population exposure conditions, by measurement or numerical
simulation, is not required when the corresponding SAR Test Exclusion Threshold
condition(s), listed below, is (are) satisfied.
For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test
exclusion thresholds are determined by the following:
[(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
