This document presents the Radio Frequency (RF) exposure assessment for the DF15T device, adhering to the guidelines set forth by the Federal Communications Commission (FCC) under §15.247(i) and §2.1091. The evaluation ensures that the device operates in a manner that does not expose the public to RF energy levels exceeding the Commission's established limits.
The report outlines the applied procedures and limits for both occupational/controlled and general population/uncontrolled exposure scenarios. It includes tables detailing the electric field strength, magnetic field strength, power density, and averaging time for various frequency ranges. The assessment also covers the predication of MPE (Maximum Permissible Exposure) limits at a given distance, utilizing the equation from OET Bulletin 65, Edition 97-01.
Test results are presented, including tune-up power, output power, antenna gain, and calculated power density for different wireless modes such as BT, BLE, WIFI 2.4G, WIFI 5.1G, and WIFI 5.8G. A simultaneous transmitting evaluation is performed for WIFI and Bluetooth, demonstrating compliance with FCC's RF exposure limits. The conclusion confirms that the maximum result is within the acceptable threshold, ensuring the device's safe operation.
