This document presents the test results for power spectral density measurements conducted on a U-NII (Unlicensed National Information Infrastructure) device. The testing was performed by Waltek Testing Group Co., Ltd., adhering to FCC regulations outlined in 47 CFR Part 15 Section 15.407(a) and following the guidelines provided in KDB662911 D01 and KDB789033 D02. The purpose of this testing is to ensure that the device complies with the power spectral density limits specified for different U-NII bands, including 5.15-5.25 GHz, 5.25-5.35 GHz, 5.47-5.725 GHz, and 5.725-5.850 GHz.
The report includes detailed measurements for various operating modes, such as 802.11a, 802.11n (HT20 and HT40), and 802.11ac (VHT20, VHT40, and VHT80), across different channels (low, middle, and high) within each U-NII band. The test setup and procedure are described, along with the equipment used for the measurements. The results are presented in tabular format, showing the measured power spectral density values and the corresponding duty cycle factors. The report also includes plots of the power spectral density for each operating mode and channel, providing a visual representation of the device's performance. The test results demonstrate that the device meets the power spectral density limits specified in the FCC regulations.
