Product Overview

What it is...

Active Testing of 4G & 5G Networks

Mobileum’s SITE ecosystem provides end-to-end active testing to monitor 5G Standalone (SA), 5G Non-Standalone (NSA), and 4G LTE networks. It ensures seamless connectivity for voice, data, video and messaging, while validating network performance under real-world conditions. The solution enables operators to monitor QoS and QoE for eMBB, VoLTE, and VoNR.

and why it matters...

Assure Experience, Monetize Networks

As operators transition to 5G, maintaining consistent service quality across 4G and 5G layers is critical. SITE detects issues before they impact users — accelerating resolution times, minimizing churn, and enabling the launch of new services with confidence.

Quick View: How It Works

Industry Challenges

Solving Quality Challenges in 5G & LTE Networks

1
  • Operators struggle to maintain consistent performance while validating 5G SA, 5G NSA, and legacy 4G LTE services simultaneously
2
  • Customer experience issues often go undetected until they impact service, causing increased churn and reputational damage
3
  • Traditional testing processes delay network rollouts and limit the ability to rapidly launch and scale new 5G services
4
  • Without real-time insights across the core, access, and service layers, operators lack the control to proactively resolve issues
Key Product Features

End-to-End 5G & 4G Network Testing

  • 5G SA & NSA Testing:
    Verifies network attach, authentication, and service availability.
  • VoNR, EPS Fallback, and VoLTE:
    Validates voice call setup, continuity, and voice quality.
  • SMS and MMS:
    Detects messaging failures and drops in performance. 

Powerful Methods for 5G & 4G Validation

  • Smartphone-Based Testing:
    Uses real iOS and Android devices to assess subscriber experience, QoS, and service accessibility.
  • 5G Radio Testing:
    Verifies network performance with dedicated probes, ensuring reliable throughput, latency, and connectivity for NSA and SA deployments.
  • Fixed Wireless Network Testing:
    Evaluates 5G-enabled CPEs for broadband access, measuring data traffic, QoS, and coverage challenges in various environments.


Core Network and Slicing Assurance

  • Core Network Testing:
    Validates 5G core functions, including network attach, authentication, session management, and user plane performance.
  • Network Slicing Assurance:
    Ensures QoS enforcement, resource allocation, and isolation across multiple network slices for enterprise and consumer applications.
  • End-to-End Visibility and Segmentation:
    Test on the radio and core to measure baseline network performance and isolate the root cause.
