Testing Alternatives for Base Station OTA Standards Metrics
Aug. 25, 2022
Wireless base station manufacturers need to ensure their products comply with international standards. To do so, they can use various methods to test RF performance. These methods, along with other test considerations, are discussed.
Recent papers have addressed making far-field measurements at much less then the traditional far-field distance, particularly for 5G MIMO test articles. These papers have focused on main beam measurements only and have stated that other normal antenna pattern metrics, such side lobe level measurements are not appropriate for this shortened distance. This paper will present main beam error from two other perspectives, looking at agreement with the previous other perspectives. In addition, the paper will present a trade study in terms of chamber size, measurement durations and measurement methods between the quasi far-field, compact range and spherical near-field approaches.
