ITU approves R&S network interactivity test

R&S’ Interactivity Test has been approved by the ITU as a standardized test procedure to evaluate 5G network performance for real-time, interactive applications. Defined in Recommendation ITU-T G.1051, the Interactivity Test measures round-trip latency, packet delay variations, packet error rates, and proofing bit rates to identify network issues that affect the quality and reliability of real-time and interactive services.

The test methodology measures latency under real network load conditions. The load patterns can be adjusted to specific use cases. All low-layer information on the packet service level is available, and an over-the-top assessment generates a network interactivity score. Information from the test can help identify data transmission bottlenecks.

According to R&S, the Interactivity Test is more granular than legacy data tests. It helps optimize network infrastructure for real-time and interactive use cases, ensuring compliance with industry standards and regulations. Moreover, it aims to improve quality of experience (QoE) and quality of service (QoS).
