5G NR Carrier Acceptance Tests

Conformance approval is one of the most important steps to bringing mobile devices to the market. With the introduction of 5G NR, the sheer number of test cases grows exponentially due the huge number of supported band combinations, deployment options and evolving standards. Major 5G operators ask for additional carrier acceptance tests to ensure cellular devices function properly on their networks. With an R&S®CMX500 based test system, Rohde & Schwarz supports carrier acceptance tests like PQA, NPT and LBS in 5G FR2. In all applications, the extremely compact R&S®ATS800R CATR chamber is used for the required over-the-air measurements. The video shows an carrier acceptance test case: Heat dissipation of a mobile device in relation to data throughput.


Verify device functional KPIs in lab using field data

Reduce time and cost by verifying important device KPIs in lab under realistic network conditions using R&S CM360o Field-to-Lab solution for 5G. Replicating field data in lab enriches the testing capability of R&S CMX500 allowing its users to deploy devices with confidence.
