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 Here, For BT Max Power(dBm) Max Power(mW) Frequency(MHz) Min. distance(mm) Calc. thresholds limit -0.16 0.964 2441 5 0.301 3.0 For BLE Max Power(dBm) Max Power(mW) Frequency(MHz) Min. distance(mm) Calc. thresholds limit -1.96 0.637 2440 5 0.199 3.0 Note: The BT/BLE does not support simultaneous transmission So a SAR test is not required
