Stories by Johanna Sochos

An expert with over 12 years of experience in signal processing and algorithm development, Johanna Sochos enjoys the analysis of large amounts of complex data and the design of smart algorithms to retrieve and analyze data. She is fascinated by the creation of models that reflect the network quality as perceived by humans. With a master’s degree in physics, the Senior Research Engineer is responsible for the specification of requirements for application and data tests. In her blog posts, Johanna Sochos examines just that – the design and evaluation of data and app tests.

Interactivity test: Examples from real 5G networks (part 3)

June 10, 2020 | by Johanna Sochos

After discussing the shift of focus in QoE measurements in 5G networks, introducing the concept of interactivity, and explaining our test approach, we will conclude this series with measurement examples from real networks, including 5G. Learn about the interactivity test in action and discover test results from different field measurements.
