Tiivistelmä
The topic of this thesis was beamforming calibration validation test automation, and it was commissioned by Nokia. The goal of this work was to explore and evaluate different testing environment options to determine the most suitable approach for this project. To find the most suitable choice, a couple different test environments were taken into comparison.
Initially, a manual environment was created to gain clear understanding of how the measurements were currently conducted and to become more familiar with the testing process. Based on the research, two alternative test environments were identified: a modified conducted environment and an Over-The-Air (OTA) environment. The modified conducted environment was an automation of the existing manual setup, using the coherent combining method for beamforming calibration. Alternatively, the OTA environment focused on using the phase measurement method for testing beamforming calibration functionality.
The result of this thesis was the successful identification of two distinct methods for beamforming calibration testing. These methods provide valuable alternatives for ensuring the accuracy and efficiency of the testing process. Further development will focus on enabling continuous operation of the testing environment and exploring the possibility of testing different radio units.
