The Network Quality Data Investigator (NQDI) is a post processing system that demonstrates the capabilities of data collection by SwissQual QualiPoc and Diversity products for network and service optimization and benchmarking. On top of all radio technologies, NQDI also provides detailed quality analysis and long-term reporting for voice and data services.

Network Quality Data Investigator (NQDI) stores all information gathered by the collection systems in a scalable database, allowing flexible data selection and filtering for detailed troubleshooting and long-term trend analysis. It combines the benefits of insights generated by high-level KPI summaries with the investigative power of detailed drilldowns.

A smart adapting GUI sensitive to contextual information enables users to focus on relevant information, while time synchronization and correlation of numerous data layers helps to automate fault categorization. The quality of voice, video, messaging and data services can be investigated using primary RF measurements, network trace events, call control parameters, IP and application level events, and voice and video quality indicators.

NQDI presents such information in time-synchronized views using maps, message monitors, grids, line graphs, bar graphs, pie charts, tables and hierarchical lists. It features multiple options for reporting, from predefined packages to guided KPI-based creation of Excel reports with a powerful report generator.
