Key points:Importance of field measurements: Traditional network planning tools and models only offer an estimated view of mobile coverage. Field measurements are conducted under real geographical and load conditions, and therefore provide a more accurate picture and can discover interferences more effectively. Coverage investigations: When deploying a mobile network, operators must adhere to regulatory standards and licensing conditions. As a result, regulatory authorities carry out field measurements on a regular or ad hoc basis to validate compliance or investigate customer complaints. This process identifies coverage gaps and areas of poor network quality, enabling regulatory authorities to take actions to enhance service quality for consumers and guide network expansion.Foster competition: If the field measurements of the coverage and performance are performed on a scale representative of a given country, the transparency of these results can promote healthy competition between operators and better service for consumers, which is essential for economic growth and social development.Measurement Techniques: The harmonized methodology for measuring and evaluating data throughput and QoE based on popular services is described in ETSI TR 103 559.

Mobile network operators worldwide face cost pressures and escalating network complexity. The advent of 5G-NR has ushered in new use cases and flexibility, but it also comes with more stringent performance and availability requirements.Machine Learning can serve as a catalyst for the market to unearth deep insights that would otherwise remain concealed. It can also significantly streamline everyday tasks by fostering a smarter system that guides users through their routine work processes, rather than obliging them to repeat each (manual) step. Rohde & Schwarz Mobile Network Testing has focused its efforts on delivering Machine Learning use cases that distill relevant insights from drive testing data, thereby offering substantial benefits to users.This educational note explains the motivation and reasoning why this kind of approach is needed, what are the benefits of the machine learning offering and it takes a deeper look into how it can be used in various levels of statistical and technical analysis. Finally, this document provides real measurement results and analysis findings based on the Rohde & Schwarz post processing SW suite SmartAnalytics and its machine learning based features Call Stability Score and Network Utilization Rating.

Modern societies worldwide depend on the performance, reliability and security of critical infrastructures and networks. There is a plethora of “new verticals” such as manufacturing, warehouse, mining, ports or other critical infrastructure, just to name a few. These “new vertical” use cases all have one common requirement: the mobile network needs to provide a superior performance compared to a commercial mobile network. In such environments 5G brings new capabilities to build fast and secure campus or private networks tuned to higher performance, which can increase productivity and efficiency. To be successful in these business-critical use cases, the wireless networks need to be as reliable as the wired ones. This educational note describes the different test methods to be able to verify the superior network performance and to help finding root causes of potential problems limiting the performance. We distinguish between passive tests and active tests.

Business-critical infrastructure: Industrial applications require extremely high reliability and availability, as any downtime can result in significant financial losses. Fundamental requirements: Industrial applications often require low latency and even more important a sustainable latency to ensure real-time communication and control. Measurement Techniques: As soon as the radio access network is used, innovative testing methods are needed beforehand to proactively test the network capability and to identify any potential issues. We propose a standard test procedure for the characterization of a network regarding industrial use-cases that covers a representative set of different, common types of network traffic.

Key Points: Mission-Critical Infrastructure: Military operations require extremely high reliability and availability, as any downtime can result in compromised missions and significant strategic losses. The reliability of communication networks is crucial to ensure seamless execution of military operations. Fundamental requirements: Military applications often require low latency and sustainable latency to ensure real-time communication and control, particularly in situations where split-second decisions can mean the difference between success and failure. This is critical for applications such as command and control systems, surveillance, and reconnaissance. Measurement Techniques: As soon as the radio access network is used, innovative testing methods are needed beforehand to proactively test the network capability and to identify any potential issues. We propose a standard test procedure for the characterization of a network regarding military use-cases that covers a representative set of different, common types of network traffic.
