Rohde & Schwarz to showcase 5G mobile network testing
Covers all phases of the product lifecycle – from R&D of RF and digital designs, design validation and integration to 3GPP-defined base station conformance and production testing.

The Rohde & Schwarz portfolio for mobile network infrastructure testing covers all phases of the product lifecycle – from R&D of RF and digital designs, design validation and integration to 3GPP-defined base station conformance testing and production testing. At Mobile World Congress 2021 (MWC21), Rohde & Schwarz will be showcasing its latest class-leading mobile network infrastructure testing solutions, which address various needs and enable the mobile industry to leverage the opportunities of 5G.

Radio access network (RAN) landscapes deploy various kinds of infrastructure equipment, ranging from macro to small cell base stations. Evolving 5G NR technology in particular makes infrastructure equipment testing challenging due to increasing MIMO complexity and beamforming, wider bandwidths and new spectrum bands up to the mmWave range.

 

R&D testing at the edge of 5G with 67 GHz vector signal generator

The Rohde & Schwarz signal generation and analysis portfolio meets 5G bandwidth and frequency requirements and includes software applications to address 5G testing challenges. At MWC21, Rohde & Schwarz will demonstrate a setup to test 5G NR physical layer parameters, which will be included in Release 17. As part of this setup, the company will present for the first time the new microwave frequency option up to 67 GHz for its SMW200A vector signal generator. The setup consists of the signal generator and the FSW85 high-end signal and spectrum analyzer, which supports image-free spectrum analysis at up to 90 GHz and up to 8.3 GHz of internal analysis bandwidth. Release 17 will include new parameters for signal bandwidth, subcarrier spacing and modulation. These key physical layer parameters are already covered by the signal generation and analysis tools, since both instruments can easily handle these demanding signals with wide bandwidth up to 2 GHz at high frequencies. Such a setup allows R&D engineers to implement and test the performance of next generation 5G components and devices. The new 5G NR features and the new frequency option for the SMW200A will be available later this year.
