Gladiator G-Station• Supports: GSM, UMTS/HSPA

and LTE, WiMAX, cdma2000 and EvDO

• Supports major drive test vendors: JDSU-NiXT, ASCOM-TEMS, Anite-Nemo, Accuver-XCAL,R&S-SwissQual, PCTEL, etc…

• Selected by Vendors and Operators as a standard post processing platform

G-Station – rich set of visualization

and analysis capabilities


Toolbox organization

Three types of analyses– Area (coverage, interference,

missing neighbor)• Examine larger area• Work with binned data

– Event (block call, dropped call, handoff)

• Examine various events during the call

– Reports (various KPI stats)• Summarize overall stats for

the drive

Analysis are “single click” with a detailed help and analysis algorithm explanation

Required data sources:– Drive test data and system reference file– Optional: Configuration dump (CM)

Main modules:– Standard Frame and State Machine– Optional: CDC

Analysis in a toolbox

Note: Organization of the analyses is the

same for all technology toolboxes


RF Optimization – Coverage

Findings:

• DL poor coverage, coverage edge, interference, antenna null

• UL poor coverage and interference

Outputs

• Map indicating problem areas and problem sites

• Report ranking problematic cells

RF Optimization – PollutionFindings:

• Isolate coverage issue from pollution issues.

• Identification on pollution areas with:

– Excessive coverage overlap (Too many servers)

– Non dominant server (Lack of dominant server)

Outputs:– Map indicating areas with

Coverage issues and areas with Pollution issues.

– Report with overall coverage performance summary.

– Report ranking problematic cells for optimization.

Help minimizing interference and improving quality

RF Optimization – Missing NeighborFindings:

• Determines missing neighbors based on phone/scanner data and system

• Determine Over shooters based on phone/scanner data and system

Outputs:– Map indicating location of missing

neighbors

– Map indicating location of Over shooters

– Report ranking the missing neighbor relationships

– Report indicating the Top 10 Over shooters

Help minimizing Drop call

RF Optimization – Cross FeederFindings:

• Identify swapped sectors

• Identify cells with coverage outside main lobe.

Output:

• Map with all the areas where coverage is outside main lobe.

• Map with highlighted cells that are having coverage outside main lobe.

• Report with detail information per cell

RF Optimization – ThroughputFindings:

• Identify areas with poor throughput

• Correlate throughput performance with RF coverage and quality.

Output:

• Map with all the areas with:– Poor Throughput

– Poor RF

– Mismatch between Quality and Throughput

• Report with throughput statistics.

RAN Optimization – Layer 3 Events

Findings:

• Analysis of both CS and PS side

• Based on Layer 3 message flow

• Identification of every abnormal events (Failures)

Output:

• Produces detailed report with call stats KPI’s

• Investigation of the abnormal failures to determine the root cause

RAN Optimization – Application EventsFindings:

• Documents events on the application layer

• Evaluates performance of each individual application

Outputs:– Map showing data events

performance

– Reports with statistics of the Application events

– RF investigation on the abnormal events.

RAN Optimization – Troubleshooting

Findings:

• Check the root cause for every abnormal events (Failures)

Output:

• Produces detailed report with reasons for the abnormal event

• Check for RF coverage issue like:

– Poor coverage

– Interference

– Swapped Sectors

– Missing Neighbors

– Overshooting cell

– Etc…

Reports - phoneUsed for:

• The reporting may be done on the entire data set or a set filtered by a polygon

• Help qualifying the RF parameter distribution

Output:

• Provides statistical summary for key RF parameters

Reports – Go/No-Go

Used for:

• Go No-Go testing

• Comparing the KPIs against the SLA thresholds

• Multiple set of thresholds may be defined

• Two kinds of KPIs– Application SLA KPIs (accessibility,

retainability, handover success, etc.)

– RF performance SLA KPIs (Rx Power, EcIo, Tx Power, etc.)

Output:

• Report indication which KPI did not meet the SLA criteria.

Reports – Site VerificationUsed for:

• Used for new site integration

• The KPIs are evaluated and compared against the thresholds

• Two kinds of KPIs– Application SLA KPIs

(accessibility, retainability, handover success, etc.)

– RF performance SLA KPIs (Rx Power, EcIo, Tx Power, etc.)

Output:

• Single Site Verification Report checking RF performance and Application performance for each sector.
