End-to-End OTA RF Testing Solution
Development is conducted using a comprehensive test instrument, employing an antenna‑over‑the‑air (OTA) radiation transmission method within a clean RF test environment corresponding to the relevant frequency range. ATE software enables automated control of the test instrument, shielded chamber, RF switch matrix, and hardware control module, while complying with applicable 3GPP standards to achieve automated acquisition, evaluation, report generation, and data storage for the terminal device’s RF and communication performance metrics.
Scheme Overview
Full-device OTA RF testing Solution
The solution is developed based on a comprehensive tester and, within a clean RF test environment spanning the relevant frequency range, employs antenna‑to‑air radiation for signal transmission. Using ATE software, it enables automated control of the comprehensive tester, shielded chamber, RF switch matrix, and hardware control module, and, in accordance with applicable 3GPP standards, implements automated acquisition, evaluation, report generation, and data storage for the terminal device’s RF and communication performance metrics.
The solution can be applied across product‑related stages, including terminal product R&D, manufacturing, and quality inspection, enabling a single comprehensive test instrument to perform parallel testing on multiple units simultaneously.
