Rohde & Schwarz and VIAVI Solutions verify their respective test equipment on correct implementation for 5G NR and LTE. This exchange between the two companies, help accelerate UE commercialization. The verification, based on the R&S CMX500 5G NR wideband radio communication tester by Rohde & Schwarz and the TM500 network tester for user equipment (UE) emulation by VIAVI.
5G NR uses a combination of several features, functions and complex algorithms, making it vital for UE manufacturers to perform extensive testing of 5G mobile devices before bringing them to the market. The thorough validation of the standardized coexistence methodology is key to the success of 5G technology. It sets the basis for the collaboration between Rohde & Schwarz and VIAVI. The cooperation ranges from RF performance testing to protocol stack verification and maximizing IP data throughout tests to support Rohde & Schwarz and VIAVI customers such as chipset and device manufacturers, operators and test houses as well as network infrastructure clients.
The test instruments enable the testing of complex 5G signalling features for NSA mode or SA mode in FR1. It includes features like DSS (dynamic spectrum sharing), LTE advanced and 5G NR carrier aggregation combinations, over-the-air (OTA) testing, but also feature verification of high-bandwidth tests in FR2 spectrum.
Charl Cilliers, Vice President of Engineering, VIAVI said: “Time to market is the number one priority for our customers, the benefit of this cooperation is that we can accelerate our technical development to launch new 3GPP features at a much earlier stage. It helps our customers achieve their goal. One of the enablers of this cooperation is the 5G testing portfolio offered by Rohde & Schwarz, together with a wealth of experience in wireless technologies in both companies.”
Christoph Pointner, Senior Vice President for Mobile Radio Testers, Rohde & Schwarz, said: “Rohde & Schwarz is pleased to cooperate with VIAVI as a leading provider of network testing equipment. When two major T&M specialists combine their expertise in joint development, the results benefit both companies and also all their customers in the network and UE testing fields.”
