Taking User Experience to the Next level
Your customer’s are not directly concerned with network service quality measures, such as jitter, packet loss and other technical parameters. Customer perceptions and loyalty are based on the quality of their experiences, like audio quality and download speeds.
However, measuring quality of experience (QoE) is far from straightforward. It requires a testing platform with the right algorithms and resources. Once they are part of the testing process, QoE metrics can be correlated with traditional KPIs to give a better picture of the overall quality.
Some benefits of the SEGRON ATF as a testing platform for overall quality are
Is call setup time considered QoE?
Yes, and it is easily measured in the SEGRON ATF through automated call handling. We measure the time it takes from pressing the Call button on the first device to the moment the second device is alerted.
In general, good QoS values are not necessarily sufficient for good QoE results. The reason for this is twofold:
Audio Quality and User Experiencee
Measuring audio QoE is much more intricate because of the many factors affecting audio quality. POLQA (Perceptual Objective Listening Quality Analysis) is the global standard for voice quality measurements.
POLQA is built on an algorithm that considers raw test and reference samples and evaluates the bandwidth of the speech path, type of speech coding, noise suppression, frequency compensation, among others.
The result is presented on a five-point opinion scale, known as the Mean Opinion Score Listening Quality Subjective (MOS-LQS), ranging from 1 for poor quality to 5 for excellent quality.
Supporting Infrastructure and User Experience
The SEGRON ATF audio architecture is built on the Audio Matrix, which consists of hardware and software components integrated within the ATF providing the following advantages:
