NQDI
NQDI: Scalable, flexible, detailed NQDI: Scalable, processing, investigation and reporting of network survey data.
Scalable, flexible, and detailed processing NQDI is SwissQual’s post-processing system for network optimization and benchmarking and is based on data produced by QualiPoc and Diversity product families.
Features • Combines high level KPI summaries with full access to detailed drilldowns • Smart adapting GUI is sensitive to contextual information • Time synchronization and correlation of numerous data layers helps automate fault categorization
“NQDI goes beyond basic post processing and allows us to get into extreme detail, even looking at voice and video MOS scores for individual calls. That’s important when the delta between being first or second for quality is just one dropped call.”
NQDI provides a detailed analysis of the quality of voice, video, and data services using primary RF measurements, network trace events and call control parameters for all radio technologies.
Correlated
Payload
GUI
Centralized
NQDI correlates information from physical, service, and application layers in time-synchronized views using maps, grids, line graphs, bar graphs, pie charts, tables and hierarchical lists.
NQDI offers extensive payload analysis of voice and video services, with onboard QoS algorithms supporting troubleshooting and optimization the end-to-end services QoS.
NQDI has a smart adapting GUI which is sensitive to the context of time & date, technology, operator, device type, map polygons, quality thresholds, and events being displayed.
NQDI is designed as a client/ server application using Microsoft SQL Server as a data repository and is fully scalable from a standalone laptop solution to large client/server enterprise systems.
Technologies
Automated
NQDI supports all the major mobile radio technologies, including GSM, GPRS, EDGE, WCDMA R99, HSDPA R5, HSUPA R6, HSPA+ R7, CDMA2000, EV-DO, IS-136, iDEN, DVB-H, WiMAX, and LTE.
NQDI has automated analysis of CS and PS calls with failure cause categorization that assists the user in finding the top most quality degrading network problems within just a few seconds.
Layers
Storage
NQDI allows time-correlated physical and protocol diagnosis across numerous layers – RF, L2, L3, TCP/IP, RTSP, UDP,H.245, H.324M, WAP, HTTP, FTP, streaming media player and more.
NQDI stores detailed information in the database instead of aggregated data and raw binary files, allowing more detailed analysis, more flexible filtering and long-term trend analysis.
Did you know? Smart Making complicated systems is hard. Making them easy-to-use is harder still. But SwissQual has taken giant steps in making systems that deliver complex answers very quickly. We not only give customers the ability to define their own bespoke KPI values, but also calculate them in real-time live, during data acquisition. That means that the KPIs c oming directl y off the networ k drives are those the customer likes to see, without waiting for any post-processing.
