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…

Combined engineering and benchmarking measurements add value

Different mobile network measurement tools target different measurement scenarios. One might be the preferred choice for collecting mass data for benchmarking; another might offer extensive possibilities for engineering and troubleshooting. Do we always know how the collected measurement data is being evaluated when we are performing the actual measurement? Most probably not. But wouldn’t it be great if we could…

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,…

Measuring quality of experience in public benchmarking campaigns

When studying rankings of mobile operators in specialist publications, you often learn about maximum download and upload speeds, the reliability and availability of offered services, and data transport performance. These technical parameters describing quality of service (QoS) are the bedrock of a reliable mobile service and a well-performing network; they are the basis for subscriber satisfaction. But are they enough…

Device integration: detective work for mobile network testing solutions

Have you ever thought about device integration? Surely, you’ve heard or read about it; for example, in our recent press release announcing the complete integration of the Samsung Galaxy S8 smartphones into our product portfolio of mobile network testing solutions. Didn’t you then wonder what exactly device integration means? Unlike competitors’ claims, device integration is everything but simply connecting user and…

What different models for predicting visual quality exist? What models are applicable for which test cases?

In a previous blog entry about the challenges of mobile video services, we discussed video quality as a perceived metric and how it can be measured subjectively in viewing sessions. In this post, we will take a closer look at automated video quality measurement methods, often called objective measurements, which are applied in real field video quality measurements. An objective…
