This document presents an RF exposure evaluation for the Tuya Wifi Fingerprint Access Control device, model TF108, and its listed variants. The evaluation adheres to ANSI and IEEE standards, as well as FCC regulations, including CFR 47 parts 1 and 2, and KDB publication 447498 D01. The device is categorized as a production unit intended for general population/uncontrolled environments and is classified as a mobile device.
The report details the limits for maximum permissible exposure (MPE) for both controlled and uncontrolled environments, considering electric and magnetic field strengths, power density, and averaging time. It includes antenna information, conducted peak output power measurements, and manufacturing tolerances for various IEEE 802.11 standards. The evaluation concludes that the device complies with FCC limits for RF exposure and SAR exclusion thresholds, assuming a minimum separation distance of 20cm from the user, as specified by the manufacturer.
