While initial 5G New Radio deployments will focus on a non-standalone (NSA) mode, which always requires an LTE connection as anchor, the next step will be deployments in a standalone mode (SA). Rohde & Schwarz and Prisma Telecom Testing have achieved another important milestone in the commercial evolution of 5G New Radio: The two companies successfully verified a 5G NR standalone registration including data transfer using a test solution based on an R&S CMX500 5G NR signaling tester and a Prisma UeSIM multiterminal simulator. The test setup provided a 5G network simulation to test a realtime connection on a carrier with 100 MHz bandwidth in line with 3GPP release 15 in standalone mode (option 2).
Using this R&S CMX500 based setup and the Prisma UeSIM, developers of 5G user equipment or network infrastructure can measure compliance to 3GPP Rel 15 standalone mode of their products already today. They can verify in detail the signaling procedures needed to establish a 5G standalone registration and a data connection. Simultaneously, they can generate data traffic to and from the Prisma UeSIM. Throughput measurements help to optimize 5G transmission settings.
