5G is the fifth generation of wireless communication technology supporting cellular networks. From GSM (2G) through to LTE (4G), each generation addresses technical challenges not overcome by its predecessor. As with previous generations, 5G requires new mobile devices and new base stations (BTS).Unlike previous generations, the use of radio beams in 5G requires completely new approaches with regard to the compliance, coverage, and quality of service testing.The new air interface is called 5G NR ("new radio"). This application note describes the measurement challenges of 5G NR and makes clear the benefits of using a monitoring receiver for measuring 5G signals.Real-world examples explain how to perform various key 5G measurements. The final section covers further 5G measurement possibilities using R&S products. "Over-the-air" (OTA) measurements are essential in 5G. This means staff from regulators and operators must work in unknown radio environments that vary according to location (e.g. urban or suburban) and mission (e.g. 5G BTS compliance testing or interference hunting). Measurement equipment must operate in a wide range of scenarios (close to the mast and far from the mast) and offer user-friendly functionality that enables the required measurements.Considering current global deployment trends, this paper focuses on the FR1 frequency band (sub 6 GHz).

Critical infrastructure: With the deployment of TDD networks, the mobile network community recognizes the critical importance of cell synchronization and the use of uniform TDD patterns across different networks for the proper operation of mobile radio networks. Variety of scenarios: Possible scenarios include cross-border situations, interactions between private campus networks and public mobile networks, and accidental synchronization chain breaks or misconfigurations within the mobile network.Measurement techniques: To quantify the effects of non-synchronized cells and using different TDD pattern in neighboring networks, R&S, in collaboration with TU Dresden and Advancing Individual Networks GmbH (AIN), conducted a measurement campaign using movable networks with full control over all network parameters. This campaign measured the effects on uplink and downlink throughput, mapping these to RSSI/RSRP values received at the interfered site.Customer benefits: The available quantification is valuable for predicting and assessing potential interference scenarios before setting up and operating a new cell site.

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.
