Correlational Analysis in QoS Parameter Assessment for 5G Emerging Networks in Poland

In this paper, we present a preliminary correlation analysis of quality of service (QoS) metrics for the upcoming fifth-generation (5G) network. This assessment was made based on drive-test measurements carried out in an urban environment for all four operators operating in Poland. The measurements were made by a professional company that assesses the quality and availability of mobile services. Our analysis is based on a Pearson correlation coefficient (PCC), which illustrates the similarities degree between two metrics. Typically, the PCC values for the two selected QoS parameters are small, i.e., the parameters are not linearly correlated. Therefore, in further analysis, we look at the distribution of parameters to indicate a non-linear relationship between them.
