Partners to test 3GPP 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 the latest Qualcomm® 212S and Qualcomm® 9205S NTN chips. The CMW500 Protocol Testing Framework scenarios and the CMW 3GPP Release 17 NTN IoT protocol enabler on a single CMW500 wideband radio communication tester from Rohde & Schwarz will help engineers assess their NTN NB-IoT devices powered by the Qualcomm NTN chips under realistic conditions. The CMW500 wideband radio communication tester emulates GSO and GEO satellite base stations in combination with the 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.
Innovators like Qualcomm Technologies are leaders in enabling IoT applications via satellite by integrating satellite connectivity options into low power wide area (LPWA) chipsets. Non-terrestrial networks are revolutionizing global coverage on land, at sea and in the air for IoT applications by providing uninterrupted connectivity. Geosynchronous orbit (GSO) and geostationary orbit (GEO) satellites ensure consistent communication by enhancing performance and user experience even under challenging conditions. The advancements are vital for the agriculture, maritime, and logistics sectors as well as for asset tracking, which all depend heavily on extensive coverage, acceptable latency and reliability.
IoT device developers must understand the unique aspects of GSO and GEO, since each orbit has special benefits. Despite their apparent movement, GSO satellites cover higher latitudes like the Earth’s poles, enhancing reach of IoT. GEO satellites are fixed in relation to Earth and provide continuous regional coverage, which is ideal for constant IoT connectivity and simplifies antenna design, reducing costs. Selecting the right orbit is vital when optimizing IoT device performance, connectivity reach and overall techno-economics.
Alexander Pabst, Vice President Market Segment Wireless Communications at Rohde & Schwarz, said: “Our extensive experience with the 3GPP wireless, satellite and aerospace ecosystems make us a trusted provider of optimized systems for an industry leader like Qualcomm Technologies in the emerging NTN market.”
