Features
Combines high level KPI
summaries with full access
to detailed drilldowns
Smart adapting GUI is
sensitive to contextualinformation
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. Thats important
when the delta between being first or second forquality is just one dropped call.
Scalable, flexible,and detailed processing
NQDI is SwissQuals post-processing systemfor network optimization and benchmarkingand is based on data produced by QualiPocand Diversity product families.

NetQual NQDI Software specification
SwissQualv.1
Post Processing PlatformNetQual NQDI with in-depth data analysis, network
troubleshooting, report generation and historical
performance trending. Flexible and customizable data
selection and filtering capabilities including time & data,
network technology, operator, device type, map polygon
regions, service quality threshold, layer 3 messages and
much more. Customizable Excel reports based on KPI with
a powerful repor t generator.
Technologies
Extensive technology test support including:
GSM, GPRS, EDGE, WCDMA, LTE, CDMA/EVDO, WiMAX,
HSPA+, HSDPA DC, iDEN, IS-136, TDMA, PSTN, ISDN
and IP.
System Architecture
Microsoft SQL Server database engine fully scalable
from a standalone laptop solution to large client/server
enterprise systems with Terminal server. Supported on
both 32- and 64-bit Windows platforms to ensure that
the user can find the optimal balance between price and
performance. Available with named and floating licensing.
NQDI runs independent of Windows Regional settings.
Data StorageStore detailed information in the database to avoid
compromising the flexibility and detailed analysis filtering.
Due to the intelligent design of the data files produced by
the SwissQual probes the import speed into the NQDI
database is extremely fast.
User Interface
Context sensitive user interface adopts the presentation
automatically to the content and technology, there is no
need to change between workspaces or rearrange any
windows manually. Customizable and detachable windows.
Drill down and visualization of information from Servi ce and
Appli cation layer s down to RF in time synchronized views
using maps, grids, line graphs, bar graphs, pie charts,
tables and hierarchical lists.
Data Selection
Flexible and customizable data selection and filtering
capabilities including time and data, network technology,
operator, provider, device type, map polygon regions,
service quality thresholds, call markers, layer 3 messages
and much more. User can save and easily reuse the most
used selection parameters from a Favorites list.
Automated AnalysisAutomated analysis of CS and PS Call s with failu re causes
categorization that assist the user in finding the top most
quality degrading network problems, detected in the
measurement data, within just a few seconds.
Voice and Video Analysis
Post processing provides in-depth voice and video analysisusing the unique SQuad, VMon and VQuad content based
objective quality algorithms and data analysis based on
correlation of information from Service and Application
layers down to RF.
Services Analysis
Analysi s of a wide range of services:
Voice telephony: CS and VoIP Speech MOS, Noise
suppression, Echo, RTT, DTMF
Data: Ping, FTP, UDP, HTTP, Data Capacity, Iperf
Browsing: WAP, HTTPS/HTTP IE
Messaging: SMS, MMS, E-mail
Video over IP: Video streaming portals including YouTube
supporting MPEG4, H.263 and H.264 streams with
resolutions from QCIF up to 720p HD
3G Video telephony
Speech Quality AnalysisDetailed and accurate analysis of all measurement values
captured with SwissQual and ITU voice MOS algorithms:
ITU-T P.863 (POLQA) full reference voice MOS (narrow &
wideband)
ITU-T P.862/P.862.1 (PESQ) full reference voice MOS
(narrowband)
SwissQual SQuad full reference voice MOS (narrow
& wideband), echo, noise suppression and RTT
assessments
SwissQual NiNa+ no reference voice MOS
Video Services Analysis
Full support for video service analysis and visual quality
assessment.
Video ser vice evaluation with success, completion and
drop ratestime to first picture, long term freezing, IP
statistics and degradation causes values
SwissQual VQuad full reference visual quality MOS
SwissQual VMon no reference visual quality MOS
IP AnalysisDedicated protocol and IP throughput analysis of Diversity
and QualiPoc probes IP trace data including DNS resolver
details. Files including PCAP IP trace can automatically be
loaded into Wireshark with NQDI time synchronization.
Reporting
More than 200 KPIs available for Service QoS and Networkperformance reporting and trending with several possible
sorting parameters including Operator, Technology and
Map Region. The extensive set of Standard Reports
includes Voice, Video, Data, Messaging, GSM, WCDMA,
CDMA, GPRS/EDGE, HSPA+, HSPA DC and LTE reports. It
is also possible to embed map plots in the reports.
Report Generator
PI report generator allows users to create their own custom
KPI reports that are saved in the database and can be
easily shared across your organization. The Excel reports
can contain success rate and average pi vot tables with
PDF, CDF and Pie charts. A trending sort function can
group the data into time bins ranging from Hour up to Year.
Map plotting
More than 500 pre-defined Map plot items in a powerfuland fully configurable plot engine which supports MapInfo
and Google Earth. Supports configurable binning on grid or
latitude-longitude precision.
User can save and easily reuse the most used plots from
a Favorites list. BTS lists for GSM, UMTS, CDMA and LTE
can be loaded. Serving sector line indicates Ser ving BTS
and BTS Coverage function displays BTS sectors coverage
for all points like a spider web. Smart window splitting
and map layer offsetting makes the analysis of multiple
networks and multiple parameters easy. The map window
is time synchronized with the analysis charts and tables.
Database Management
NQDI databases are easily managed with the integrated
data management tool, without the need for specific SQL
server or database knowledge. NQDI can create and build
historical databases to provide the global overview and
trending over time.
Web Compatibility
Fully compatible with NetQual NQWeb p latform for
corporate wide distributed presentation and reporting.
