User Quality of Experience (QoE) In IEEE 802.11 Wlan: A Comprehensive Review
Article Sidebar
Main Article Content
Abstract— Quality of Experience (QoE) has become a central metric for evaluating user satisfaction in telecommunication networks, yet most research has focused on LTE, GSM, and UMTS, leaving IEEE 802.11 WLANs still the backbone of global connectivity less explored from a QoE perspective. This paper presents a comprehensive review of QoE in WLANs, integrating technical, regulatory, and business viewpoints. We examine QoE models and their interplay with IEEE 802.11 standards (802.11n/ac/ax/be), and analyze application-level QoE for video streaming, VoIP, online gaming, live event broadcasting, AR/VR, and web browsing. The mapping between Quality of Service (QoS) metrics and user-perceived QoE is discussed, along with methodologies for measurement, simulation, and testbed evaluation. Special attention is given to challenges arising in dense, moderate, and home deployments. Building on this analysis, we propose a priority-aware framework that links QoS indicators, subjective user perception, and contextual application importance (e.g., emergency announcements, interactive gaming, or live sports streaming). We introduce mathematical models for embedding QoE into WLAN operations and identify open challenges, including ML-driven prediction, privacy-preserving telemetry, and QoE-aware scheduling. Our study concludes with recommendations to guide future research and industry practices toward user-centric WLAN design.
