This document details the radiofrequency (RF) exposure evaluation for portable devices, adhering to FCC guidelines outlined in § 15.247(i) and § 1.1307b(1). It ensures that the public is not exposed to radio frequency energy levels exceeding the commission's safety standards.
The evaluation focuses on the 1-g SAR test exclusion thresholds for devices operating between 100 MHz and 6 GHz, with test separation distances of ≤ 50 mm. The calculation is based on the formula: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR.
The document provides specific data for different modulation types, including 8DPSK and GFSK (2Mbps), detailing the frequency, maximum power (dBm), tune-up power (dBm and mW), test distance, and resulting SAR values. All results are compared against the exclusion thresholds to ensure compliance.
Power and distance values are rounded to the nearest mW and mm, respectively, before calculation. When the minimum test separation distance is less than 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. The final result is rounded to one decimal place for comparison purposes.
