3.5 Voice Quality Analysis
Voice quality samples are displayed on the table and map event pop-up form as shown below:
Figure 50: Voice Quality events
The PESQ values for P.862.1, P.862 and Audio Level (dB) are displayed for each sample. The sample
audio may be replayed by clicking on the loudspeaker icon. This is often helpful to understand the nature
of any degradation in the audio.
PESQ results are analysed to produce a summary for each base station site as shown below on the map
base site pop-up form:
Figure 51: Voice Quality analysis for a base site
Overall average scores are produced for uplink and downlink separately as well as a combined value plus
values for each frequency used at the base station. The data for the analysis is taken from the same time
period as currently selected for the map analysis.
The same analysis is also displayed on the ‘VQ Analysis’ main tab for all base sites as shown below:
