Quality of Experience (QoE)

Monitoring communications quality is necessary to detect performance issues and understand if the overall quality matches with the user expectations.

Quality of Experience (QoE) measures how satisfied users are with a network service based on their subjective perception. Unlike Quality of Service (QoS), which focuses on technical metrics (e.g., latency, jitter, packet loss), QoE evaluates the actual end-user experience—such as video streaming smoothness, call clarity, or web browsing responsiveness. QoE is important from various points of view including:

• User Satisfaction: Even if network metrics appear good, poor QoE leads to frustration (e.g., buffering videos or choppy VoIP calls).
• Business Impact: Bad QoE can result in lost customers, reduced productivity, or negative reviews.
• Proactive Troubleshooting: Identifying QoE issues early helps prevent major service disruptions.
