It can partially be explained by the fact that European operators have more 1 and 2-digit channel codes in their test lineup. We can see that the top 4 performing operators for this channel change test are North American, with a Channel Change Time under 2 seconds. Still, it is interesting to observe that even though all the operators are advertising a download speed above 50Mbps, the Witbe VQ-MOS score is averaging at 3, which is decent but not at the value of around 4 that would be expected for HD content. This shows that in the center of Montreal, all tested mobile operators are providing an equivalent level of Quality of Experience. No major discrepancies were noticed between the four mobile operators. Performances KPIs (App Launch Time, Login Time, and Video Initial Buffering Time) are all within the optimal range that we determined based on our expertise. By looking at the medians of the four KPIs that were measured, we see that the overall Quality of Experience when viewing videos through mobile networks in Canada is good.
