Rohde & Schwarz presents test solution for 5G NR mobile networks

September 10, 2018 // By Christoph Hammerschmidt
With the world's first commercially available solution for testing 5G New Radio (5G NR) cellular networks, users in the 5G ecosystem and regulators can accurately measure coverage in 5G NR cellular networks - one of the biggest challenges in network planning. It also verifies the proper operation of the beamforming function and the interaction between 5G and other technologies.

The solution presented includes a mobile radio scanner with matching 5G NR scanning software and the R&S ROMES4 Drive Test Software. The solution has already proven itself in practical use in pre-commercial 5G NR trial operation, which Rohde & Schwarz carried out for a network operator and a provider of 5G NR infrastructure.

Users can choose between two mobile radio scanners - the ultra-compact R&S TSME6 Drive Test Scanner and the R&S TSMA6 Autonomous Mobile Network Scanner with integrated network PC. Equipped with 5G NR scanning software, both mobile radio scanners cover standalone (SA) and non-standalone network architectures (NSA). In addition, the R&S ROMES4 Drive Test Software analyzes and visualizes all existing 3GPP technologies such as GSM, UMTS/HSPA and LTE, including the IoT technologies NB-IoT and LTE-M. For field measurements, the necessary measuring instruments can be stored in a backpack or shoulder bag together with a suitable antenna.

The supplier has prepared the R&S ROMES4 Drive Test Software so that the first 5G NR devices such as evaluation boards, USB dongles or smartphones can be connected as soon as they are available. This allows users to evaluate the performance of these devices at an early stage and investigate their interaction with a real 5G NR network.

The test solution is integrated into the Rohde & Schwarz Mobile Network Testing smart platform. This software suite offers powerful, intuitive analysis functions to optimally use the acquired measurement data throughout the entire test cycle - from verification in the laboratory and acceptance in the field to troubleshooting, optimization, benchmarking and monitoring.

Rohde & Schwarz will present its new solution for testing 5G NR mobile radio networks to the public for the first time at the Mobile World Congress Americas 2018 (Hall South, Booth p.2814).
