Abstract: A proactive service quality monitoring by means of advanced expert-driven field test analysis is of utmost importance for performance optimisation in contemporary operating wireless cellular communication networks. This monitoring requirement is particularly emphasized in mobile broadband-based networks such as HSPA due to inherent high-interference and network dynamism with multiple sources of uncertainties such as multipath radio wave propagation channel conditions which directly influence the data transmission quality. In this research, modern experimental equipment has been explored to critically investigate the performance of live HSPA commercial networks using significant signal coverage and Quality of Service (QoS) parameters at radio link and network levels. By using Radio Frequency failure (RF) detection matrix and drill down analysis on collected drive test data, the network coverage and quality problems has been identified. The impact of dynamically changing network condition on the end user experience which are indicated by specific channel signal quality and data rate metrics are also graphically presented. The research is concluded with splendid steps and recommendations on how to improve the overall performance of the HSPA and the effective deployment of future networks in the studied locations.
