SAR Exclusion 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,25 where • f(GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation26 • 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. Max Power in mW = 501 mW Antenna Gain = 3.3 dB Power with antenna gain = 1070 mW 263.5𝑢𝑠 Duty Cycle Correction = 100 𝑚𝑠 = 0.002635 = 0.2635% Corrected Power = 2.81945 mW Min. Test Separation Distance = 1 mm Frequency of Operation = 2402 MHz 2.81945 𝑚𝑊 X√2.402 = 0.87393854 5 𝑚𝑚 END OF TEST REPORT p1810006_FCC_Part 1.1310_Rev 2.0 Page 4 of 4
