According to KDB 447498 D01 General RF Exposure Guidance



At 100 ㎒ to 6 ㎓ and for test separation distances ≤ 50 ㎜, the SAR test exclusion threshold is
determined according to the following


   [(max. power of channel, including tune-up tolerance, ㎽) / (min. test separation distance, mm)]
   x [√f(㎓)] ≤ 3.0

1. SAR test exclusion threshold
Frequency : 2 480 ㎒ (min. separation distances = 0 ㎜)
SAR test exclusion thresholds(5 ㎜) = 3 x 5 / (√ 2.480 ) = 9.525 ㎽

  Max. tune-up           SAR Test Exclusion
   tolerance(㎽)         Thresholds(5 ㎜) (㎽)
         2                      9.525

Calculation value : 2 (㎽) / 5 (㎜) x √ 2.480 = 0.63
So, Calculation value ≤ 3.0

Remark:
-Max. conducted power (㎽) : maximum tolerance power of EUT (3 ㏈m)
-Max. conducted power 1.995 (㎽) is closet 2 (㎽), so 2 (㎽)was calculated.
-When the minimum test separation distance is < 5 ㎜, a distance of 5 ㎜ is applied to determine
SAR test exclusion.


2. Conclusion : No SAR is required.
