Benefits of RAN Monitoring

Correlate RAN Performance with Core Network, Service, and Customer Information

Polystar brings more than 30 years of experience to the delivery of robust, real-time monitoring and analytics solutions, delivering insights and supported by customizable workflows to meet your unique requirements. Our RAN monitoring solution seamlessly extends our proven 5G SA capabilities, providing the scale and performance you need for business-critical service assurance.

Drill Down into Detailed RRC Insights at Subscriber Level

With our RRC protocol monitoring solution, you can easily extract key information such as connection setup and release events, handover performance, signal quality, resource allocation, RRC state transitions, and paging and response delays. These insights help you to proactively address subscriber-level issues, such as dropped connections, slow data speeds, and disrupted or intermittent service.

Capture Issues and Access Root Cause Analysis Details from the RAN

Detailed analysis of RRC signaling enables you to understand changes in RAN signal strength. You can measure any degradation in real-time, analyze signal strength for UEs, determine interference, and check congestion at individual cell sites. Easily review cell overload conditions and detect capacity issues that lead to congestion, so you can optimize resource allocation for consistent service.

Leverage Radio Coverage Maps to Minimize Drive Test Requirements

RRC monitoring helps you to reduce costs by Minimization of Drive Test (MDT). By discovering black spots, misconfigurations and RF issues, you can take action remotely, driving efficient and faster operations. Our solution also helps you to plan new cell sites, replace underperforming equipment and manage RAN investments more effectively, including densification for the most demanded locations.

Use Cases

RAN Monitoring

Coverage and radio performance maps

Coverage and Radio Performance Maps

Our Radio Access Network monitoring solution visualizes radio performance as geomap data on top of Google maps. This enables users to investigate and troubleshoot radio access network coverage issues and drill down to root causes. The RAN monitoring solution enables operator users to detect interference problems and detect overshooting cells and other coverage issues. Visualized detection of traffic hotspots is helpful in cell planning.

Customer Analysis Based on E2E Data

With our solution, operators can drill down to reported issues and investigate the full end-to-end signaling flow. Geomaps enable you to visualize the relationship between RRC measurements and customer experience. Users can correlate RRC data with network-wide information to view the impact of radio issues on others in the same area. You can also zoom from a view of impacted customers to a geographic view of affected areas.

Evaluating device performance in telecom

Device-level, Radio-specific KPIs for Evaluating Device Performance

Our RAN monitoring solution enables operator users to investigate the radio performance of specific devices in given geographic locations using geomaps. Users can compare device performance in different radio environments and run statistical correlations between problems with device types and their radio performance. This enables operator users to differentiate between device- and network-originated issues, and to target their resolution actions.
