How to deliver consistent ultra-low latency, high-throughput, and total reliability across complex networks

According to a recent report, as of the end of 2024, the telecommunications industry boasted 2.25 billion 5G connections worldwide. This rapidly growing rate of adoption has put greater pressure on communications service providers (CSPs) to deliver superior user experience. Given the significant investments involved, CSPs are under the gun to provide consistent, high-quality 5G experiences, which require ultra-low latency, high throughput, and rock-solid reliability across increasingly complex cloud-native networks.

This level of performance is needed to offer the unmatched user experience required to drive promising new revenue-generating opportunities. In order to optimize the 5G user experience, CSPs will need data observability into their networks. Data observability from NETSCOUT gives carriers the continuous, packet-level visibility they need to understand what subscribers are actually experiencing and to make precise, timely improvements.

6 Ways Observability Can Optimize the Subscriber Experience

The following are six ways CSPs can use that observability to optimize 5G user experience and improve security:

1. Gain end-through-end visibility across hybrid 5G architectures. 5G user experience is only as strong as the weakest link in the service path. Making things more challenging, 5G isn’t a single network. It encompasses a complex ecosystem that includes RAN, core, edge, cloud, and applications, which often span multiple vendors and environments. Without comprehensive observability, operations teams are left with gaps in visibility, making troubleshooting difficult and raising the specter of endless finger-pointing between stakeholders. With NETSCOUT’s data observability, carriers can capture and analyze packet data across RAN, 5G core (standalone [SA] and non-standalone [NSA]), multi-access edge computing (MEC)/edge, and cloud. This end-through-end lens lets teams pinpoint whether poor user experience is due to radio conditions, network performance, transport congestion, or the application itself. Faster, more accurate problem isolation translates directly into fewer dropped sessions, less downtime, and more consistent user experience. When user experience is assured, so too are business benefits.
2. Use Smart Data and DPI to understand real user experience. To really understand the user experience, true observability is needed. NETSCOUT uses deep packet inspection (DPI) to turn packets into what we call Smart Data, enriching it in real time with context about subscriber, service, device type, location, and slice. This NETSCOUT Smart Data reveals throughput, latency, jitter, call setup time, attach/registration success, and video quality, revealing exactly how a 5G feature or app is impacting the user experience. Instead of waiting for customer complaints or generic alarms, operations teams can proactively manage the experience as it’s happening. This shift to experience-centric analytics is essential for 5G success.
3. Power AIOps and closed-loop automation with high-fidelity data. Automation is only as good as the data feeding it. NETSCOUT’s high-fidelity, curated, artificial intelligence (AI)-ready data serves as the foundation for observability and AIOps, enabling better outcomes in complex environments such as 5G. As a result, CSPs can use this data to train anomaly detection models that spot early signs of congestion, signaling storms, or misbehaving virtual network functions (VNFs). They can drive closed-loop policies that automatically scale resources, reroute traffic, or adjust quality-of-service (QoS) profiles before customers notice a problem. It allows them to continuously refine planning and capacity management using objective experience data instead of complaints alone. This results in a more resilient, self-optimizing 5G network that ensures user experience is flawless even under stress.
4. Accelerate root-cause analysis and reduce mean time to repair (MTTR). When issues inevitably occur, whether due to device updates, configuration errors, software defects, or external attacks, user experience is immediately in peril. In a highly competitive 5G market, long resolution times translate into churn, negative social media commentary, and increased support costs. NETSCOUT’s packet-level observability accelerates MTTR by providing forensically rich, historical packet data that lets engineers “rewind” and replay events leading up to incidents. It correlates alarms and key performance indicators (KPIs) back to specific network elements, interfaces, or application components. It also offers cross-domain insights that show how an issue in one domain cascades into visible user impact. Instead of engaging multiple teams to manually gather metrics, events, logs, and traces (MELT), carriers can rely on a shared, authoritative source of truth. That reduces war-room time, speeds up troubleshooting, and ensures consistent service quality, even as networks grow more complex.
5. Monitor 5G slices and differentiated services in real time. 5G monetization hinges on understanding how subscribers and enterprises actually use the network. A core promise of 5G is differentiated experience via network slicing, such as ultra-reliable low-latency slices for industrial Internet of Things (IoT), high-bandwidth slices for streaming, or premium slices for VIP customers. NETSCOUT’s solution gives visibility and analytics per slice so CSPs can monitor SLAs, QoS, and key KPIs in real time. With slice-level observability, providers can detect when a slice is under-delivering, verify that enterprise SLAs are actually being met, and prioritize resources dynamically to protect high-value services during congestion. This has the effect of turning slicing from a theoretical feature into a measurable, marketable differentiator.
6. Integrate security visibility to protect availability and trust. User experience isn’t just about speed and latency; it’s also about safety and availability. Attacks such as distributed denial-of-service (DDoS), signaling abuse, and sophisticated application-layer threats can cripple 5G services or cause intermittent degradations that look like random slowness to subscribers. NETSCOUT combines observability and cybersecurity, using packet-based visibility, to improve mobile network security and DDoS protection for service providers. By feeding the same Smart Data into both performance and security analytics, CSPs can detect and mitigate volumetric and application-layer attacks that impact 5G core and edge. They can identify stealthy threats hiding inside normal traffic that might degrade services over time and can maintain service continuity during attacks, protecting customer trust and regulatory SLAs. Embedding security into the observability strategy ensures that great user experience also means the network is secure and always available.

Observability Gives Real-time Insights

Optimizing 5G user experience is all about seeing the network clearly—end-through-end, in real time, and from the user’s perspective—and then acting decisively on that visibility. In short, CSPs can leverage NETSCOUT’s data observability to deliver a 5G experience that is fast, reliable, differentiated, and trustworthy.
