Unlimited Connectivity Made Real: Rohde & Schwarz Exhibits Mobile Test Solutions at MWC Barcelona 2022

February 14, 2022

The mobile industry is set to come together in Barcelona at Mobile World Congress once again, scheduled to happen from February 28 to March 3, 2022. Under the motto “unlimited connectivity made real,” Rohde & Schwarz will showcase a wide variety of leading test innovations at the Fira Gran Via in hall 5, booth 5A80. The exhibits cover three main themes: ultimate 5G connectivity, the expanded mobile ecosystem and the future of mobile. 

Ultimate 5G connectivity

5G is already all around, with unprecedented speed of adoption in devices, mobile network infrastructure and network deployment. Standalone 5G deployments will ramp up even more in 2022 to unleash the true potential of 5G with aggregated frequency bands of up to 52.6 GHz and maximum end-to-end throughputs higher than 10 Gbps. Rohde & Schwarz provides leading-edge test and measurement solutions for the complete 5G ecosystem and all its lifecycle stagesfrom R&D to manufacturing of devices and infrastructure equipmentand across all the necessary stages for a network operator. 

Rohde & Schwarz is bringing its well-established R&S CMX500 5G radio communication tester with a major upgrade to MWC Barcelona 2022. Eliminating the complexities of 5G NR device testing, the new R&S CMX500 one-box tester combines ease-of-use and superior performance in a single instrument. Highly-integrated, users can test 5G mobile devices and chipsets in all possible 5G NR network deployments and frequency ranges with it, including FR1, FR2 and LTE bands. The simplified setup in one easy-to-use test platform results in an extremely small footprint in the lab or the production line. The R&S CMX500 one-box tester is capable of validating 10 Gbps end-to-end (E2E) IP data performance, which is necessary to enable eMBB use cases like 4K and 8K video streaming or augmented reality applications. 

The R&S ATS800R compact antenna test range based 5G NR mmWave test chamber complements the R&S CMX500 setup at MWC 2022 to demonstrate over-the-air testing. With its small footprint, wide frequency range, flexibility and broad range of extension options, the R&S ATS800R provides a solid and future-proof environment for FR2 testing needs.

With the roll out of 5G networks, small cells are gaining momentum. They offer network operators the possibility to increase the capacity of existing wireless networks and meet the demands for data capacity that come with 5G use cases. At MWC Barcelona 2022, Rohde & Schwarz will showcase a new tailored solution designed specifically for testing of small cell infrastructure equipment operating in FR1. The new single-box tester will combine vector signal generator (VSG) and vector signal analyzer (VSA) in one instrument. Two independent TRX channels will cover all FR1 frequency bands up to 8 GHz and offer flexible bandwidth configurations. A comprehensive signal generation and analysis test suite for 5G NR and LTE will provide preconfigured test routines according to 3GPP requirements, which will help manufacturers measure the radio performance of their FR1 small cell access points and related products in the production line, but also in the lab.

For the test of small cell infrastructure equipment operating in mmWave range (FR2), Rohde & Schwarz has upgraded the R&S CMP200 radio communication tester with a new option. Designed for R&D and production environments, the R&S CMP200 is a non-signaling solution for 5G mmWave RF parametric testing. OEMs of FR2 small cells can benefit from the unique features of the R&S CMP200 like ultrafast measurement speed and parallel testing of multiple DUTs in lab and production. 

In order to make networks ready for the 5G expansion, fast and efficient cable and spectrum measurements at base stations are key. For this application, Rohde & Schwarz has extended its popular rugged handheld R&S Spectrum Rider FPH family with three new base models with tracking generators offering measurement frequencies up to 13.6, 26.5 and 44 GHz. The R&S Spectrum Rider FPH was the industry’s first handheld spectrum analyzer to deliver solid RF performance for measurements in the field and in the lab. Large buttons and a multi-touch gesture screen make the instrument very easy to operate. 

The disaggregation of radio access networks through Open RAN (O-RAN) signifies a major change for infrastructure providers. It is vital to ensure the interoperability of open virtual network equipment from different vendors. Rohde & Schwarz provides high performance signal generators and signal analyzers to verify the conformance of O-RAN radio units, which support both the O-RAN Alliance and 3GPP test specifications.

To deliver the ultimate 5G device experience, smartphones are not complete without other wireless technologies. Rohde & Schwarz offers with the R&S CMP180 radio communication tester a future-proof non-signaling testing solution for wireless devices in research and development, validation and production. Together with advanced frequency, bandwidth and RF capabilities, it enables testing of new wireless technologies such as Wi-Fi 6E, Wi-Fi 7 and many more. Additionally, the doubled number of analyzers (2 x VSA), generators (2 x VSG) and RF ports (2 x 8) enable simultaneous measurements of technologies and devices in a VSA/VSG single-box tester. 

Network operators rolling out 5G networks have the opportunity at MWC 2022 to learn about the Rohde & Schwarz network performance score (NPS), a harmonized test methodology for QoE-centric mobile network quality and performance assessments which forms the foundation for guided network optimization—fully transparent, independent from the respective network infrastructure and globally comparable. Plus, a cloud-based big-data and machine learning assisted network analytics suite to build sustainable and automated network intelligence will be on display at MWC 2022.

Expanded mobile ecosystem

Industrial-grade mobile networks, particularly 5G NR, open up new use cases for cellular technology, expanding the mobile ecosystem beyond the traditional world of private subscribers to include enterprise, logistics, healthcare, manufacturing, finance, a host of secure applications and much more. Two of the primary applications that extend the mobile ecosystem are private networks for smart factories as well as automotive, with a special emphasis on C-V2X use cases. Rohde & Schwarz addresses both applications for their demanding test requirements in the lab and in the field regarding network availability, security, quality and performance. 

A full range of solutions to test and improve the quality and performance of 5G public and private networks are displayed at MWC Barcelona 2022.
