This document presents the RF exposure evaluation for the HP2413ANC device, adhering to FCC regulations outlined in §15.247(i), §1.1307 (b), and KDB447498. The evaluation ensures that the device operates within safe radio frequency energy levels, protecting the public from excessive exposure.
The evaluation utilizes the SAR-based exemption formula of §1.1307(b)(3)(i)(B) to determine if the device qualifies for SAR exemption. This formula considers the maximum time-averaged power or effective radiated power (ERP) of the device in relation to a threshold Pth (mW). The method is applicable for separation distances between 0.5 cm and 40 cm, and frequencies from 0.3 GHz to 6 GHz.
The document details the calculations for ERP, including antenna gain and conducted transmit power. The SAR exclusion threshold level is calculated based on the ERP and separation distance. The results indicate that the source-based time-averaging conducted output power is significantly below the SAR threshold, confirming that the HP2413ANC device complies with SAR requirements and does not require further testing.
