This comprehensive test report assesses the frequency stability and antenna requirements of 5G WLAN devices, ensuring adherence to FCC regulations (47CFR Part 15 Section 15.407(g)) and ANSI standards (C63.10-2020+A1-2024). The report details the test procedures employed, including measurements of frequency error under varying temperature and voltage conditions. The frequency error is calculated using the formula (fc-f)/fc x 106 ppm, with a limit of ±20ppm.
The report also addresses antenna requirements, confirming that the device utilizes an antenna with a specified coupling to the intentional radiator, complying with FCC regulations to prevent the use of unauthorized antennas. The test results demonstrate that the device maintains frequency stability within the specified limits under all tested conditions, including extreme temperatures ranging from -30°C to 85°C and voltage variations from 85% to 115% of the nominal value. Furthermore, the report references MPE test report WTX25D02025644W004 and includes photographs of the test setup and EUT (Appendix-CDW208821C-Photos).
