Analysis of Service Quality Parameters and Their Relationship With User Perception In Videoconferencing Platforms Over 4g Networks

The relationship between Quality of Service (QoS) parameters in 4G networks and user perception in videoconferences in Latin American academic settings has limited academic evidence. This study analyzes how technical network metrics influence the perceived Quality of Experience (QoE) during videoconferences. An experiment was conducted with 30 university students using tools such as Zoom and Microsoft Teams. During 60-second sessions, network traffic was captured using Wireshark to measure jitter, packet loss, and bidirectional utilization, while participants evaluated their experience through surveys using the Mean Opinion Score (MOS) metric. Multiple linear regression analysis revealed that jitter and downstream throughput significantly influenced the Quality of Experience, while packet loss and upstream throughput did not show a significant impact. The model explains only 9.7% of the variability in QoE, confirming that contextual factors such as socioeconomic level, mood, screen size, phone performance, and user expectations contribute substantially to the final experience in video conferencing over mobile networks.
