A measurement campaign quantifying the impact of intermodulation in 5G TDD networks
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.

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.

5G 是支持蜂窝网络的第五代无线通信技术。从 GSM (2G) 到 LTE (4G) 的每一代通信技术都需解决上一代技术遗留的技术难题。和之前的技术一样，5G 也需部署新的移动设备和基站 (BTS)。和前几代技术不同的是，5G 中的无线电波束使用需要采用全新的一致性、覆盖范围和服务质量测试方法。这种新空中接口被称为 5G NR（“新空口”）。本应用指南描述了 5G NR 的测量挑战，并清楚阐明了使用监测接收机测量 5G 信号的优点。指南通过实例说明如何执行各种重要的 5G 测量。最后，指南介绍了使用罗德与施瓦茨产品可执行的其他 5G 测量。“空口”(OTA) 测量在 5G 应用中至关重要。监管机构和运营商的相关人员必须在城区或郊区等不同地方探索多种未知的无线电环境，以便执行 5G BTS 一致性测试或干扰捕获等各种任务。测量设备必须可在靠近和远离天线杆的不同应用环境中工作，并提供易用功能以执行所需测量。本应用指南遵循目前的全球部署趋势，重点讨论 FR1 频段（即 Sub-6 GHz 频段）。
