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

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 3-part series with measurement examples from real networks, including 5G. We will show the interactivity test in action and present test results from different real field measurements. Before going further, let us briefly revisit…

Electromagnetic field measurements in 5G: Overview and concepts (part 1)

What is different about 5G NR from a technology perspective? In layer 1, it is the heavy use of beamforming and frequencies above 3 GHz. Beamforming is used to overcome the increased path loss, especially at 3 GHz and above. However, beamforming and frequencies above 3 GHz have raised a large number of discussions among the population, especially about electromagnetic…

Interactivity test: Concept and KPIs (part 2)

In the first part of this series, we discussed how the focus of QoE measurements in 5G networks shifted to measuring the quality of actively used services and introduced the concept of interactivity. We have defined the interactivity of a network as the measurable continuity and latency of a given bit rate. Now, we will look into interactivity measurements, traffic…

Interactivity test: QoS/QoE measurements in 5G (part 1)

Most users have the impression that 5G will just provide more data rate. This is true; the transport capacity will increase due to the additional spectrum made available to operators through the licensing of 5G frequencies. This will surely improve the download experience, especially in heavily loaded areas. However, 5G is more than just more data rate. The main advantage…

Machine learning: Time-based anomaly detection (part 3)

Anomaly detection is a much-appreciated tool by data scientists. It aims to find data samples that do not conform to the regular distribution of the dataset to which they belong. Finding anomalous samples, also known as distribution outliers, provides valuable insight that often correlates with defects or errors in the data collection process (e.g., faulty or misconfigured equipment). This blog…

Network Performance Score: How to conduct NPS benchmarking campaigns

The Network Performance Score (NPS) reflects the perceived technical performance of a mobile network or one of its subsets such as region, period, or technology. The overall NPS score is the combination of carefully considered and weighted main key performance indicators (KPI) for a wide range of services that are essential and exemplary for service quality. But what needs to…

Network Performance Score: Configurator for step-by-step campaign setup

The Network Performance Score (NPS) is an integral part of our benchmarking and analytics products based on the Smart platform. In previous posts, we have discussed how the score weights the key performance indicators for a wide range of services and combines them into an overall score. With the configuration of the NPS being pertinent to reliable results, we have…

Real 5G UE measurements – achieving gigabit speeds

Solutions from Rohde & Schwarz mobile network testing have been used in 5G engineering use cases and pre-commercial trials since the beginning of 5G. With the introduction of our 5G scanners (R&S®TSMA6 and R&S®TSME6), in combination with the drive test software R&S®ROMES4, we have taken the lead in testing 5G networks. However, measuring the real user experience in 5G and…

5G site testing and troubleshooting

Commercial 5G rollout is happening, and the rate of deployment of 5G non-standalone (NSA) sites is increasing every day. Each new installation needs to be commissioned and verified to ensure correct network performance and quality of service (QoS) delivered to end users over the 5G network. 5G site testing requires specialist mobile network testing solutions that meet the testing demands…
