A solution for evaluating the video quality of 5G devices was recently developed by a partnership between Spirent Communications and TOYO using Anritsu’s SmartStudio NR (SSNR) Network Simulator and Spirent’s Attero and Umetrix Video software. Operating as a 5G Call Box, Anritsu's MT8000A simulates a 5G base station and core network with a state-machine-based GUI.
The solution can simulate a range of 5G network conditions, such as Standalone (SA) and Non-Standalone (NSA) topologies at FR1 or FR2 frequencies, without creating protocol scripts. Throughput, mobility, VoNR, EPS-Fallback, SMS, CMAS, CDRX, and other functional tests can be performed with the GUI. SSNR flexibility and ease in reproducing a 5G network situational environment to analyze video quality. Automation environments can be configured quickly, and Spirent’s Attero can emulate situations accurately and in a repeatable manner to fully stress-test Next-Gen IP platforms and networks.
Changeable filters test the effect of impairments on specific packets or types of traffic, and the Umetrix Video evaluation system scores the QoE (Quality of Experience) using Video Mean Opinion Scoring (V-MOS) from the receive-side only, supporting video-streaming services and video-content analysis, allowing faster and lower-cost repeatable design, regression, and competitor benchmarking tests.
