多輸入多輸出空口(Multiple-Input-Multiple-Output Over-the-Air, MIMO OTA)量測已經成為第四代和第五代行動通訊產品效能驗證的必備項目。在傳統MIMO OTA量測過程中工程師被限制只能在電波暗室旁監控即時數據,而無法進行其他工作。此外,每筆量測結果皆產生大量資料因此需要耗費大量人力和時間成本來整理和分析。因此,本論文研製即時監控MIMO OTA量測流程的遠端系統以解決上述問題。
本系統包含遠端控制介面、量測管理資料庫,以及樞紐分析工具。遠端控制介面可即時監控量測結果於瀏覽器上以利工程師遠距操作,在量測數據異常當下能遠端暫停電波暗室內之量測,並使監控量測不受地域影響;量測管理資料庫在後端將大量資料進行分類管理;樞紐分析工具能自動交互比對資料庫內的資料,可減少人員操作失誤因而保障資料正確性以及縮短分析時間。實測結果顯示,本系統有助於即時管理量測結果並快速分析產品效能,進而提升電波暗室之使用效率及降低量測時間成本。
The Multiple-Input-Multiple-Output Over-the-Air (MIMO OTA) measurement has become mandatory for evaluating performance of the 4th and 5th Generation communication devices. In the conventional MIMO OTA measurement process, it is inconvenient that the engineers are restricted to monitor the real-time results only next to the anechoic chamber. Moreover, it is costly for time and manpower to organize and analyze the massive amount of measurement data generated.
Therefore, in this thesis we resolved the aforementioned problems by developing the remote monitoring system for real-time MIMO OTA performance measurement, including the remote control interface, the measurement management database, and the pivot analysis tool.
The proposed remote control interface allows the engineers far away from the anechoic chamber to not only monitor the real-time measurement result on the web browser but also pause the measurement process when the abnormality appears. Therefore, the proposed interface breaks the geographical limits. The proposed database classifies massive amount of measurement result data in the back-end. The proposed pivot analysis tool automatically performs cross-comparison among the massive amount of measurement data in the front-end on the engineers’ demand to compare the MIMO OTA performance among multiple devices, such that to reduce not only the misoperation from human but lead time for data analysis.
Our proposed system is proven beneficial to efficiency in both the anechoic chamber utilization and the data analysis time for devices after being evaluated in the real-world MIMO OTA measurement process.
