Rohde & Schwarz at MWC 2024: T&M solutions for the mobile industry that enable connection and empower innovation

Rohde & Schwarz at MWC 2024: T&M solutions for the mobile industry that enable connection and empower innovation Always at the forefront of technological innovation, Rohde & Schwarz is shaping the future of the mobile industry with its comprehensive range of test and measurement solutions. The company will showcase at MWC Barcelona 2024 under the motto Enabling Connections, Empowering Innovations a wide-ranging portfolio that helps industry leaders, manufacturers and visionaries turn their ideas for new mobile products, applications and technologies into reality.

Rohde & Schwarz will showcase its solutions for the mobile industry at MWC Barcelona 2024.

The mobile industry will once again gather in Barcelona for the Mobile World Congress from February 26 to 29, 2024. At the Fira Gran Via in hall 5, booth 5A80, Rohde & Schwarz will be showcasing a variety of innovations covering four areas that correspond to the event's main themes: 5G and beyond focuses on a variety of solutions driving the evolution of 5G and the emergence of 6G; Connected everything features solutions for the seamless integration of connected ecosystems; Private networks covers performance and quality assurance for business and mission-critical communications; and Game changers allows visitors to take an early leap into tomorrow's augmented reality applications.

5G and beyond

A large part of the Rohde & Schwarz booth will be dedicated to solutions that enable the mobile ecosystem and empower next-generation connectivity. Visitors will experience the transition from 5G to 5G Advanced through several demonstration of the R&S CMX500 one-box 5G signaling tester (OBT) and other state-of-the-art radio communication testers covering the latest technology enhancements:

Rohde & Schwarz is pushing the limits of seamless global coverage over land, sea and air with its test solutions for non-terrestrial networks. NTN-NR directly links smartphones and other 5G devices with satellite-based services. In a demo setup, the R&S CMX500 mobile radio tester will simulate a wide range of network conditions to ensure NTN-NR devices perform flawlessly anywhere in the world.

Paving the way for the 5G NR FR3 frequency band, which will provide wider bandwidth to tomorrow's mobile networks, the R&S CMX500 and R&S CMP200 radio communication testers are ready for R&D and production tests. At MWC, visitors will see signaling and non-signaling measurements, supporting the respective frequency range from 4 to 20 GHz. Furthermore, a high-performance signal generation and analysis setup for early FR3 research will be on display, featuring the latest vector signal generator and analyzer products, R&S SMW200A and R&S FSVA3000.

Another highlight at the show booth are FR1 RF and RRM measurements with the smallest footprint in the market. Rohde & Schwarz has enhanced the R&S CMX500 to provide 3GPP conformance tests for radio resource management and RF inband in a single box.

The integration of untrusted non-3GPP networks such as public hotspots and home or corporate WLAN with the 5G core network is a crucial aspect of the 5G evolution. Therefore, Rohde & Schwarz has added Wi-Fi 7 capabilities to the R&S CMX500 multi-technology multi-channel signaling tester. 5G WLAN offloading capabilities are included, as well, with the test platform acting as an N3IWF gateway. With this, also Voice over Wi-Fi (VoWiFi) can be tested all in a single box. In addition, the R&S CMP180 radio communication tester will verify a WLAN waveform with 480 MHz bandwidth in loop-back mode, a potential waveform candidate discussed in regards to a not-yet defined Wi-Fi 8 (IEEE 802.11bn) standard, attesting that the instrument is future-proof for users in both, R&D and production.

Other demonstrations around 5G at the Rohde & Schwarz booth will address 5G Broadcast, where Rohde & Schwarz has been leading the industry and proving the technological maturity through real-world demonstrations and practical solutions worldwide. At MWC, the company will demonstrate how broadcasters, network operators and content providers can leverage 5G Broadcast for new business opportunities, building on the technology's high quality of end-user experience and excellent spectrum efficiency.

When it comes to emerging O-RAN technologies for network infrastructure, Rohde & Schwarz offers a proven, automated test solution together with VIAVI Solutions that helps to improve network efficiency and achieve energy savings. Radio units of an Open RAN based network (O-RU) contribute greatly to the total power consumption. VIAVI's TM500 O-RU Tester offers energy efficiency focused O-DU emulation test scripts. The O-RU activity versus power consumption is monitored using the R&S RTO oscilloscope. The R&S NGP power supply units power the O-RU and monitor voltage and current statistics over time. The central O-RU Test Manager application from VIAVI controls the full set-up.

To ensure optimum quality of service (QoS) and quality of experience (QoE) in public and private 5G mobile networks, Rohde & Schwarz will showcase its tailored solution portfolio. Mobile network testing experts will present a broad range of live product demos, test scenarios and an ETSI harmonized methodology for systematic network performance improvements. The solutions empower customers worldwide to verify and ensure optimum performance for human and machine end-users along the entire network lifecycle of public as well as business and mission critical mobile networks.

Looking beyond 5G and onward to 6G, Rohde & Schwarz will exhibit a number of concise test solutions in Barcelona to enable applied research for example in the Terahertz regime in the D-Band (110 to 170 GHz). Part of these demonstrations will be the new R&S SFI100A wideband IF vector signal generator. The compact, user-friendly instrument for demanding
