No Simultaneous transmission
RF Exposure Evaluation
According to KDB 447498 D01 clause 4.3.1 a), transmission from 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)]
Calculation Details
| Parameter | Value |
|---|---|
| Frequency | 2.480GHz |
| Max. peak conducted output power (including tune-up tolerance) | 0.10mW |
| Minimum test separation distances | <5mm |
Note: Power and distance are rounded to the nearest mW and mm before calculation. The result is rounded to two decimal places for comparison.
Result: 0.03
Requirements: ≤ 3.00 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR
Conclusion
The source-based time-averaged maximum conducted power of Bluetooth operation satisfied RF exposure requirements. The corresponding SAR test exclusion threshold was satisfied 4.3.1a) requirements. Measurement or numerical simulation is not required.
