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
GLADIATOR INNOVATIONS PROPRIETARY, 2014
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
GLADIATOR INNOVATIONS PROPRIETARY, 2014
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 – 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 – 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.
