T&M specialists Rohde & Schwarz and VIAVI Solutions verify their respective test equipment on correct implementation for 5G NR and LTE. This exchange between the two companies will help accelerate UE commercialization. The verification is 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 various 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. This sets the basis for the collaboration between Rohde & Schwarz and VIAVI, who over the past year have cooperated on speeding up the integration of a variety of essential 5G NR features. The cooperation ranges from RF performance testing, to protocol stack verification, and to maximum IP data throughput tests to support Rohde & Schwarz and VIAVI customers such as chipset and device manufacturers, operators and test houses as well as network infrastructure clients.
Rohde & Schwarz and VIAVI work together to implement new 3GPP 5G NR features at the same time and understand the integration challenges involved. When developing a new feature, virtual testing is an option, but ultimately a UE device is necessary to verify the newly developed feature. Using the R&S CMX500 from Rohde & Schwarz as a network infrastructure emulator alongside the VIAVI TM500 UE emulator is a versatile alternative to a real device. This enables both companies to achieve their goals in providing customers with stable, mature, and wider 5G 3GPP feature coverage at an accelerated rate.
