Dynamic spectrum sharing (DSS) enables 5G NR and LTE to coexist by sharing the same frequency spectrum. In the video, Rohde & Schwarz demonstrates its verified test solutions based on the R&S CMX500 and R&S CMW500 radio communication testers and the R&S CMsquares unified test software, along with a MediaTek Dimensity 5G smartphone representing the end-user device. This scenario simplifies signaling testing with DSS in non-standalone (NSA) mode.
