Testing 5G QoE: The role of standardization organizations (part 3/3)

The previous parts of this blog series drew the conclusion that the critical nature of some applications demands that solutions for testing 5G QoE must be independent, transparent and traceable to certified international standards and not aligned to proprietary techniques or individual network equipment vendors. The more one considers the mission-critical applications arising from 5G cases, the more it reinforces…

Testing 5G QoE: Defining and measuring 5G QoE test cases (part 2/3)

In part one of this blog series, we established that an expanded test methodology with new test cases is required to characterize the quality of experience (QoE) of 5G networks. Let’s now take a closer look at how to define and set up QoE test cases for these new “user” experiences. First, we need to understand the requirements of the…

Testing 5G QoE: Use cases, services and a new QoE paradigm (part 1/3)

Visibility of subscribers’ quality of experience is something operators have sought to measure since the early days of mobile networks. In this three-part blog series, we consider the emergence of 5G, the new use cases and services it brings, and the necessity to rethink the approach to measuring network performance and the quality of experience (QoE) of 5G networks. From…

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 QoE of mobile data applications, e.g. Facebook (part 1 of 3)

Today, there are a huge number of apps available for smartphones covering almost any use case one can think of. Network providers want to ensure that their mobile connection offers everyone a smooth usage experience, especially for the most popular smartphone apps such as Facebook. To do this, they need targeted mobile data application tests. In this blog series, we…

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…
