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.

The strict requirement of network synchronization is as old as digital cellular mobile networks. As soon as cells have a neighbor relationship, network synchronization is mandatory in both the frequency and time domains in order to ensure UE QoE and performance (Handover, MIMO, data throughput, etc.). This educational note describes how 5G NR with its extremely flexible specifications is affected by these synchronization requirements, and how it can be measured?
