Today’s increasing network complexity requires an increased level of intelligence in order to evaluate network and service performance and take action to improve it. Data collected during measurements campaigns represent a mine of information, but without a proper analysis layer the potential of such information remains unexploited. While evaluating the collected data is imperative, critical decisions should be made based on automatically validated data that is in accordance with the highest quality standards.
SwissQual’s Network Quality Data Investigator (NQDI Classic) is a post processing system that maximizes the potential of data collected by QualiPoc and Diversity products for network and service optimization and benchmarking. Based on data from all radio technologies, NQDI Classic provides automated data validation, detailed quality analysis and troubleshooting, and long-term reporting for voice and data services.
NQDI Classic combines the benefits of insight generated by high-level key performance indicator (KPI) summaries with the investigative power of detailed drilldowns. This allows for the generation of comprehensive reports and maps to benchmark networks and easily identify critical areas with underperformance.
In addition to traditional network related analysis – from layer 1 and layer 3 – and service related analysis based on IP and application layers, NQDI Classic provides KPIs representing user perception for voice and video services, e.g. Mean Opinion Score (MOS). In case of low MOS values, industry unique quality codes can directly point to the underlying causes in the network.
