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 equation and threshold in Note 1 must be
applied to determine SAR test exclusion.




Note 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 4.1f) is applied to determine SAR test exclusion.

Per FCC KDB 447498 D01v06, the SAR exclusion threshold for distances ≤50mm is defined by the
following equation :

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

Base on the maximum conducted power of the antenna to use separation distance,
SAR was not required;
Bluetooth : [(0.195 / 5) * √2.480] = 0.77 (≤ 3.0)
Bluetooth LE : [(0.196 / 5) * √2.480] = 0.81 (≤ 3.0)

Result : As a result of the calculation above, the SAR test is exempt.
