Non Terrestrial Networks
Discover the essentials of Non-Terrestrial Network (NTN) testing, from latency and signal quality to audio MOS quality and data performance.
Overview of Non Terrestrial Networks
Non-Terrestrial Networks (NTNs) represent an evolving frontier in telecommunications, offering connectivity through satellites, High Altitude Platforms (HAPs), and drones. Testing NTNs is crucial to ensure reliability, seamless integration with terrestrial networks, and optimal user experience.
(NTNs) address critical connectivity challenges by extending coverage to remote, rural, and underserved areas where traditional terrestrial networks are impractical or too costly to deploy. They provide reliable communication during natural disasters and emergencies, support IoT applications in agriculture, maritime, and aviation sectors, and enable seamless global connectivity for mobile users. NTNs also play a vital role in bridging the digital divide, ensuring equitable access to high-speed internet and modern communication services worldwide.
Challenges and solutions
Key Aspects of Non Terrestrial Network Testing
Audio MOS (Mean Opinion Score) Assessment:
-
Conduct subjective and objective evaluations of audio quality during voice calls over NTNs.
-
Assess parameters such as clarity, latency and jitter to ensure high-quality voice communication.
-
Validate user experience for applications like VoIP, emergency communications, and remote conferencing.
Device Testing:
-
Assess the performance of user devices, such as smartphones, IoT devices, and terminals, in NTN environments.
-
Test device compatibility with NTNs, including signal acquisition, data transfer rates, and power management.
-
Evaluate how devices handle transitions between terrestrial and non-terrestrial networks to ensure uninterrupted service.
Latency and Bandwidth Testing:
-
Measure round-trip delays and available bandwidth to ensure compliance with service level agreements (SLAs).
-
Simulate real-world conditions to validate user experiences.
Handovers Between Networks:
-
Evaluate smooth handovers between NTNs and terrestrial networks (e.g., satellites to cellular networks).
-
Test protocols and mechanisms for uninterrupted connectivity during user mobility.
Interference and Signal Quality:
-
Analyze signal-to-noise ratios and mitigate interference caused by environmental and atmospheric factors.
-
Test the robustness of NTN systems in adverse weather conditions or high-altitude scenarios.
