1. RF Exposure Evaluation

1.1. Limits

According to KDB 447498 D01 General RF Exposure Guidance v06
4.3.1 Standalone SAR test exclusion considerations
1) 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
•   3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below
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 according to 5) in section 4.1 is applied to determine SAR test exclusion.


2) At 100 MHz to 6 GHz and for test separation distances > 50 mm, the SAR test exclusion threshold is
determined according to the following, and as illustrated in Appendix B:
a) [Power allowed at numeric threshold for 50 mm in step 1) + (test separation distance - 50
mm)·( f(MHz)/150)] mW, at 100 MHz to 1500 MHz
b) [Power allowed at numeric threshold for 50 mm in step 1) + (test separation distance - 50
mm)·10] mW at > 1500 MHz and ≤ 6 GHz


3) The 1-g and 10-g SAR test exclusion thresholds for below 100 MHz at test separation distances ≤ 50 mm
are determined by:
a) The power threshold at the corresponding test separation distance at 100 MHz in step 2) is
multiplied by [1 + log(100/f(MHz))] for test separation distances > 50 mm and < 200 mm
b) The power threshold determined by the equation in a) for 50 mm and 100 MHz is multiplied by ½ for test
separation distances ≤ 50 mm
c) SAR measurement procedures are not established below 100 MHz. When SAR test exclusion cannot be
applied, a KDB inquiry is required to determine SAR evaluation requirements for any test results to be
acceptable. Note: when the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to
determine SAR test exclusion.

Based on The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances
≤ 50 mm and the formula below:




The tune-up power is 0.5dB, so the maximum conducted power we used to calculate RF
exposure is 10.66dBm.
