Best practices for mobile network testing for business-critical applications
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.

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.

Die strikte Notwendigkeit der Netzsynchronisation ist so alt wie die digitalen Mobilfunknetze selbst. Sobald Zellen als Nachbarn betrieben werden, ist eine Netzsynchronisation sowohl im Frequenz- als auch im Zeitbereich unerlässlich, um die Endnutzer-Servicequalität (UE QoE) und die Leistung des Netzes (Handover, MIMO, Datendurchsatz usw.) zu gewährleisten. In dieser Educational Note wird beschrieben, wie 5G New Radio mit seinen extrem flexiblen Spezifikationen von diesen Synchronisationsanforderungen betroffen ist und wie dies gemessen werden kann.
