This document presents the RF exposure evaluation for a device with FCC ID: 2AMBW-BP100, conducted according to §15.247(i), §1.1307, and KDB447498. The evaluation ensures that the device operates within the FCC's guidelines for radio frequency energy exposure, protecting the public from excessive radiation levels.
The document outlines the general frequency and separation-distance dependent MPE-based effective radiated power (ERP) thresholds, referencing Table B.1 [Table 1 of §1.1307(b)(1)(i)(C)] for exemption from further evaluation. It also provides formulas for calculating the power threshold (Pth) based on frequency ranges.
Specifically, the evaluation focuses on BLE (Bluetooth Low Energy) operation, considering antenna gain, conducted transmit power, EIRP, and ERP. The maximum output power is specified, and the MPE limit is calculated for general population and uncontrolled exposure in the 2.4GHz frequency range. The document concludes that compliance with the MPE limit is ensured by maintaining a minimum 20cm separation between the transmitter's radiating structure and the user or nearby persons.
