With this demo we present our MNT solutions for UE and network engineering, troubleshooting and Open RAN testing. Engineering activities are typically aimed at verifying the performance of technology features and services in the early network lifecycle phases, such as lab or field trials. This is specially in focus at this time of the year, where new devices based on the latest chipsets, such as Qualcomm, are coming to the market. We already support UE engineering of the latest x70 Qualcomm Modem, which comes in Samsung S23 series. A troubleshooting activity can be triggered by any indication of a localized performance degradation. The focus is here to localize and remove the issue causing specific degradation in network. With the displayed setup, we can successfully cover both use cases in FR1 and FR2 frequency ranges, now up to 53 GHz with the new TSMS53DC downcoverter. Rohde&Schwarz Mobile Network Testing offers you complete portfolio to cover all test phases of your network lifecle. Reach out to us for further information.
