Today’s increasing network complexity requires an increased level of intelligence 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 II is the post processing system that maximizes the poten-tial of collected measurement data for network and service optimization and benchmarking. Based on data from all radio technologies, service quality and network information, NQDI II provides automated data validation, detailed quality analysis and troubleshooting, and long-term reporting.

NQDI II The source of insights for business decisions

Rohde & Schwarz NQDI II 3

Key Use CaseBusiness intelligence for benchmarking and optimizationNowadays, mobile operators need to reconcile decreasing revenues from traditional communication services with in-creasing CAPEX and OPEX investments that are necessary to manage the increased data usage. With innovative services and superior subscriber quality (QoE), they want to differentiate themselves from the competition and thus look for ways to make networks more efficient through focused investments.

High-quality benchmarking has proven to be highly bene-ficial to top mobile operators facing those challenges: it provides a reliable, accurate, and reproducible way to mea-sure their subscribers’ QoE and to compare themselves against competitors. A challenge, however, is to navigate through the vast amount of data collected during bench-marking campaigns and to derive actionable insights. Tra-ditional tools do not offer the necessary flexibility, requirehigh and non-intuitive customization, and, last but notleast, lack ease of use.

NQDI II, the business intelligence platform for bench-marking and optimization data, changes all of that. It com-bines business intelligence with traditional data analysis and offers unparalleled ease of use. Intuitive workflows, designed around practical use cases, allow fast statistical analysis and flexible troubleshooting. Workflows can be easily created, modified, and shared, increasing productiv-ity and knowledge reuse. SQL databases, combined with online analytical processing (OLAP) cubes, provide an extremely fast execution of data slicing-and-dicing and enable full interactivity, introducing a new concept for reporting. Drilldown and filtering from big data to single measurement values are also possible. Consequently, the insights gained through high-quality benchmarking data empower engineers to take action and managers to make strategic decisions – with just a few clicks.

At a glanceı NQDI II is the new generation post processing software

platform that effectively turns rich drive test data into smart insights. The implemented OLAP engine guaran-tees consistency and offers slice-and-dice multidimen-

sional data presentation and analysis features.ı The interactive and user-friendly analysis and reporting

interface allows to process and display comprehensive measurements more efficiently than with any other

system, from big data to single measurements. ı Intuitive and powerful drilldown functions, combined

with the power of SwissQual’s NQDI Classic, provide comprehensive service optimization and in-depth quality of service measurements analysis with SwissQual’s

unique root cause analysis.

NQDI IIThe fastestway from datato insights

Product HighlightsSlice-and-dice data enables faster and greater insightsNQDI II empowers users to browse through the entire collection of measurement data for network and service optimization and benchmarking. For fast information access, all data is processed through the NQDI II OLAP cubes. Data can also be filtered without waiting times, statistical results can be created on the fly. In a user- friendly graphical interface, results are presented in a consistent manner so that engineers, but also executives, can quickly find relevant information. This is particularly helpful when comparing information for trending and historical analysis. Multi-dimensional presentation capa-bilities with slicing-and-dicing functions offer powerful and valuable insights from the collected data. Reporting is easy and interactive thanks to the possibility to con-veniently change dimensions, values, filters, views, etc.

Use case driven operation results with ease of useThe logical workflows in NQDI II guide users through the whole process of turning measurement data into valuable insights. The structured approach ensures high efficiency when extracting relevant information or creating a report. During the starting-up of NQDI II, users can choose from an array of different use cases and then simply follow the predefined workflow. NQDI II by design has the same ease of use as a web browser and is therefore highly intuitive. Any statistic can be visualized in multiple views by simple drag-and-drop in a user-friendly “what you see is what you get” user interface. This relieves the need for dedicated training and maintaining highly specialized engineers, which results in significantly lower operational costs. Also, larger groups of users have access to the collected data, thus maximizing the reuse of information and the overall return on investment.
