RF EXPOSURE EVALUATION

Product Specifications

Standard Requirement for RF Exposure

According to § 15.247(i) and § 1.1307b(1), systems operating under these provisions must ensure the public is not exposed to radio frequency energy levels exceeding Commission guidelines. Refer to KDB 447498 D01 General RF Exposure Guidance v06, section 4.3.1.

The 1-g and 10-g SAR test exclusion thresholds for 100MHz to 6GHz at test separation distances ≤ 50mm 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 SAR 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.
• Test exclusions apply only when the minimum test separation distance is ≤ 50mm and for transmission frequencies between 100MHz and 6GHz. If the minimum test separation distance is <5mm, a distance of 5mm is applied to determine SAR test exclusion.

Routine SAR evaluation, as required by § 2.1093, uses measurements or computer simulation. If routine SAR evaluation is not required, portable transmitters with output power exceeding the applicable low threshold require SAR evaluation for TCB approval.

SAR Test Exclusion Data

According to KDB 447498, no stand-alone SAR evaluation is required for the BT antenna, and no simultaneous SAR measurement is required.
