This document presents an RF exposure evaluation for the BC660K-GL module, ensuring compliance with FCC guidelines. The evaluation is based on MPE (Maximum Permissible Exposure) limits and considers both single and simultaneous transmission scenarios. The report references subpart 15.247(i) and subpart 2.1091 of FCC regulations, as well as KDB 447498 D04 Interim General RF Exposure Guidance.
The evaluation utilizes frequency and separation-distance dependent MPE-based effective radiated power (ERP) thresholds to determine exemption from further evaluation. The report includes tables outlining ERP limits for various frequency ranges. The analysis considers the tune-up conducted power and antenna gain declared by the applicant. The worst-case ratio for simultaneous transmission is calculated to ensure compliance with the overall exposure limits.
The results indicate that the device complies with RF exposure guidelines, provided that the equipment is placed at least 20cm from nearby persons. The report concludes that the BC660K-GL module meets the necessary RF exposure requirements for safe operation.
