Rohde & Schwarz collaborates with Qualcomm to test 3GPP Rel. 17 GSO and GEO satellite chipsets for IoT-NTN

Rohde & Schwarz, in collaboration with Qualcomm Technologies, will conduct a broad range of NB-IoT over NTN tests that address the many challenges inherent to satellite-based non-terrestrial networks that use geosynchronous orbit (GSO) and geostationary orbit (GEO) constellations. The test set covers time and frequency synchronization from prolonged delays and the Doppler effect, low signal-to-interference-plus-noise ratio (SINR), power saving mechanisms, satellite ephemerides, GNSS acquisition and more.

These tests will be a validation tool for Qualcomm Technologies’ latest NTN chips, the Qualcomm® 212S and Qualcomm® 9205S. R&S CMW500 Protocol Testing Framework scenarios and the R&S CMW 3GPP Release 17 NTN IoT protocol enabler on a single R&S CMW500 wideband radio communication tester will help engineers assess their NTN NB-IoT devices powered by Qualcomm Technologies’ NTN chips under realistic conditions. The R&S CMW500 wideband radio communication tester emulates GSO and GEO satellite base stations in combination with the R&S SMBV100B, which generates GNSS signals. Establishing a real-time, comprehensive connection with the simulated GSO/GEO satellite network lets engineers test relevant signaling and RF scenarios in line with 3GPP Release 17.
