VIAVI Solutions GEOperformance Overview VIAVI NITRO GEO captures, locates, stores and analyzes data from all subscriber events, giving operators a rich source of location aware, subscriber-centric insights to significantly improve network performance and enrich the QoE. This intelligence creates a true understanding of the customer experience to accurately improve network performance and enrich the subscriber experience. NITRO GEO GEOperformance, powered by the Network Integrated Test, Real-time analytics and Optimization (NITRO) intelligence platform, uses location intelligence to transform RAN planning and performance engineering by increasing operational efficiency, and significantly increasing return on investment, while delivering game changing improvements in the network performance actually experienced by customers. Transform RAN planning and performance engineering by increasing operational efficiency, and significantly increasing return on investment, while delivering game changing improvements in the network performance actually experienced by customers with analyses such as: • Roamers Analysis • Special Events analysis • Small Cell planning • Handset analysis • Impact Assessment • Coverage and Capacity Planning • VoLTE Analysis • Subscriber Application Awareness • Indoor/Outdoor Analysis

The flexible user interface of GEOperformance allows engineers to view maps and tables showing RF KPIs such as signal strength and interference, based on actual measurements geolocated to building level accuracy. These maps and tables can be analyzed and filtered to identify problem areas such as areas of high drop call rates. Individual calls can be selected and complete Layer 3 detail viewed to establish root cause. The automated problem detection functionality rapidly guides engineers to areas of the network that do not meet defined KPI thresholds. Sophisticated automated optimization features...

GEOperformance can be used to analyze an extensive range of KPIs such as: Call blocks (Accessibility) / Call drops (Retainability) Usage Carrier Aggregation Utilization • Signal strength, quality and interference • Handset performance • subscriber / cell performance These can be considered on a network, technology, equipment, region, cell, specific location, user defined polygon, service, subscriber and/or handset basis for different time periods during a day, 24 hours per day, every day. Roamers Performance Analyses A detailed geographic breakdown of roamer traffic by country and by operator,...

Prepare prior to the event to ensure network coverage and then monitor the event itself. VIAVI has supported events such as the World Cup, Super Bowl and supported a customer with the Olympics, for both in preparation of and during the entire event. Specific events may include: • Sporting events • Corporate Customers By using geo-located data from real subscriber calls, GEOperformance provides a clear view of the network as the subscribers experience it.

• VIP call failure location and diagnosis including layer 3 messaging • Show every leg of a session not just the start and finish • Show locations of blocks or drops during a VIP's journey • Identify the issues immediately: - Multi-RAB drop due to missing neighbor - Voice drop possible due to poorer SNR condition for the type of handset a VIP uses Device and handset segmentation and performance analysis across the network • Pinpoint problematic devices and device behavior to help you define the planning, optimization or performance evaluation strategies and priorities. • Locate and analyze specific...

Key Features and Capabilities Visualization The flexible user interface allows viewing of maps and tables showing RF KPIs such as signal strength and interference, based on actual measurements geolocated to building level accuracy. These maps and tables can be analyzed and filtered to identify problems such as areas of high drop call rates. Individual calls can be selected and complete Layer 3 detailed view to establish root cause, all from within the same GUI and across multiple RAN technologies. Additionally, Layer 7 detailed view allows for analysis of service / application metrics such as...

GEOperformance Metrics NITRO GEO captures and geolocates every voice call and data session on the network. These connections and sessions are broken into segments where key events such as handovers or bearer changes occur, allowing the changing experience over the path of a mobile session to be accurately captured for analysis. For each session the following details are captured (see User's and Technical Guides for a complete list of call, segment, and/or connection details by technology). • Call start time • Call duration • User identification (IMSI) • Device identification (IMEI, IMEI SV, TAC)...

Data can be visualized through a variety of maps, tables and charts. GEOperformance is highly flexible allowing users to define report content and layout. To maximize efficiency, powerful template features allow reports to be predefined so that users can quickly create reports. Templates allow the user to define input variables such as customer, cell, or handset type such that a user can rapidly create a report featuring just the information required for the problem under investigation. This combination of capabilities allows operators to define workflows and methodologies centrally, and ensure...

Monitoring/optimizing network quality When viewing a map within GEOperformance for a region, cells with active alarms or configuration changes can be highlighted and displayed on a dedicated layer of the map. This allows an engineer to rapidly identify cells of interest and those events or changes that could be contributing to poor performance. Troubleshooting customer impacting network events When troubleshooting a customer impacting issue, GEOperformance provides a number of methods to identify which cell or cells are causing or contributing to the problem such as a “Top N” table. From any...
