The subject of the thesis was the development of Sequence Creator Tool (SCT) which is an application that is used to create test sequences in a new state-of-the-art radio test environment at Nokia testing laboratory facilities. The aim was to develop a tool that enables fine granular control of antenna patterns created by the user, creation of test sequences for the new test environment, as well as management of user equipment (UE) attenuation and speed values. The Wall test environments are complex test environments that utilize a large array of antennas on a wall to simulate the movement of UEs, such as mobile phones. The work was commissioned by Nokia Oyj.

The implementation started with gathering of theoretical knowledge about the test environment for which the tool was developed. The initial design for the tool had been documented before the thesis was started, although it was still very much in its infancy. The new tool was intended to offer similar capabilities as the existing Wall Control Tool. With this tool however, it was time consuming to create Wall sequences especially when tens of UEs were used. The objective of the SCT was to simplify and accelerate the creation of custom test sequences for UEs and to automatically handle the conflicts and limitations of test environment control hardware.

Based on the gathered theoretical knowledge, a suitable implementation for the tool was decided and further improved during the development. As a result of the thesis the first version of the SCT was designed and developed for fifth generation (5G) radio testing. The project also emphasized the need for tools that can adapt to the fast evolution of 5G radio testing. Additionally, the project contributed to building personal academic understanding of the challenges and opportunities in the field of 5G radio testing.
