Tiivistelmä
This bachelor’s thesis was a project made for Nokia Networks. Nokia Networks is a subsidiary of Nokia Corporation which is a global multinational company focusing in telecommunications, information technology and consumer electronics.
The aim was to create an automated test environment for a 5G radio’s power supply unit by using another radio unit’s power amplifier modules as its adaptive load. This way a power supply designer can create very realistic power ramps to test their new design instead of using inadequate artificial loads. The radio unit acting as a load can be easily configured to use different signals and power levels by using a custom graphical user interface software. The software automates many complicated tasks, such as starting the unit which would otherwise be very time consuming.
A 5G 64T64R massive MIMO radio unit was selected and modified to suit this project’s needs. A custom Python software was then created from scratch to communicate with the selected radio unit. Necessary measurements were done to verify the test environment’s proper functionality.
