This document presents an RF Exposure Evaluation for the device identified by FCC ID 2BMW5-AF-11. The evaluation adheres to the guidelines outlined in section 1.1307(b) of the FCC regulations, focusing on the environmental impact of human exposure to radio frequency (RF) radiation. The report details the limits for Maximum Permissible Exposure (MPE), considering both occupational/controlled and general population/uncontrolled exposure scenarios.
The evaluation utilizes the Friis transmission formula to calculate power density (Pd) based on output power (Pout), antenna gain (G), and distance (R). The report includes tables specifying electric field strength, magnetic field strength, power density, and averaging time for various frequency ranges. The test procedure involves enabling the Equipment Under Test (EUT) to transmit and receive data at the lowest, middle, and highest channels. The results for BLE mode are presented, demonstrating compliance with the MPE limit. The antenna gain is also specified.
