Network Performance Score: initiate improvements with a QoE-centric score

There are various scores, as in scoring methods, claiming to measure the performance of mobile networks on the market. Some scores are based on plain technical metrics, others on quality of experience (QoE) measurements or surveys. Which score should a mobile network operator (MNO) choose? The one providing the highest score? The cheapest one? The one based on technical scores…

Quality of experience: are you really taking care of it in your mobile network?

Quality of experience (QoE) is crucial for the success of mobile network operators because subscribers are increasingly sensitive to the perceived quality of applications in mobile networks. Operators will only grow their subscriber base if they can lure subscribers from competing operators by offering a better perceived QoE. In a recent webinar, we provocatively asked the question “Are you really…

Measuring QoE of mobile data apps for network optimization (part 3 of 3)

How can mobile app testing support network optimization? In previous posts, we explained how you could assess the QoE of data applications on smartphones by measuring the success rate and duration of a series of actions. Based on large-scale real field measurement data, we showed how the duration saturates at higher available network speeds and examined the causes of this…

Measuring QoE of mobile data applications: behind the scenes (part 2 of 3)

In the previous post, we explained how to measure QoE of mobile data applications on smartphones by means of success rate and the duration of a series of actions. Based on large-scale real field data, we showed how the duration saturates at higher available network speeds. But where does saturation come from? And what is going on in the background,…
