This document presents an RF exposure evaluation for the device with FCC ID 2A7A6-PFC18. The evaluation adheres to the guidelines specified in KDB 447498 D01 V06 and 1.1307(b) to assess the environmental impact of human exposure to radio frequency (RF) radiation. The report details the limits for Maximum Permissible Exposure (MPE) for both occupational/controlled and general population/uncontrolled environments, outlining the electric field strength, magnetic field strength, power density, and averaging time.
The Friis transmission formula is used to calculate power density, considering output power, antenna gain, and distance. The evaluation includes test results for WiFi 2.4G mode, presenting output power to the antenna, power density at a distance of 20cm, and compliance with MPE limits. The device demonstrates compliance with RF exposure limits for all tested WiFi modes (802.11b, 802.11g, 802.11n HT20, and 802.11n HT40), ensuring safe operation within established regulatory standards.
