4.1 SAR Test Exclusions Applied _Bluetooth 3.0
According to the FCC KDB 447498 D01 v06 section 4.3.1, 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:
a) 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
Calculation Result:
Tx frequency range: 2 402 MHz ~ 2 480 MHz
SAR Consideration Min. test separation distance: 5 mm
Maximum Output Power: 1.25 mW
The Highest RF channel frequency: 2 480 MHz
| Mode | Frequency [MHz] | Maximum Allowed Power [mW] | Separation Distance [mm] | ≤ 3.0 for 1g SAR |
|---|---|---|---|---|
| Bluetooth 3.0 | 2 480 | 1. | 5 | 0.3 |
Based on the maximum output power of Bluetooth 3.0 and antenna to use separation distance, Bluetooth 3.0 SAR was not required.
