Rohde & Schwarz announced that the company has successfully verified NTN NB-IoT devices test cases of work item 333 using its R&S CMW500 radio communication tester.
Rohde & Schwarz made this announcement during the recent Conformance Agreement Group (CAG) #77 meeting.
This new Conformance approval allows the Global Certification Forum (GCF) to activate the work item in their device certification program.
Manufacturers of IoT chipsets, modems and end devices as well as test houses can now rely on the proven Rohde & Schwarz solution to bring next-generation IoT devices based on non-terrestrial networks (NTN) to the market, enabling ubiquitous connectivity on land, at sea, and in the air.
Conformance approval is a major step in bringing devices for the Internet of Things (IoT) to the market the T&M major company said in its official release.
To ensure that these devices work properly, they need to be certified by testing laboratories accredited by certification bodies such as GCF, PTCRB or CTIA.
With the successful verification of the 3GPP Rel. 17 NTN NB-IoT test cases in work item 333 at the CAG #77 meeting, using the R&S CMW500, the Global Certification Forum was able to activate the work item, kicking off conformance testing for NTN NB-IoT devices.
Rohde & Schwarz drives roll-out of NTN NB-IoT devices technology with new GCF-certified conformance test cases.
With this accomplishment, Rohde & Schwarz together with tier 1 chipset vendors like Qualcomm Technologies, Mediatek, and Sony Semiconductor Israel’s Altair and their respective platforms have contributed significantly to the adoption of non-terrestrial network-based IoT use cases spanning multiple sectors such as smartphone, consumer, automotive, agriculture, maritime, logistics, and mining. The NTN NB-IoT protocol test cases of work item 333 cover NTN-specific signaling aspects for NB-IoT devices as specified in 3GPP Rel.17 TS 36.523-1.
Rohde & Schwarz has equipped its market-leading NB-IoT solution with 3GPP Rel. 17 NTN features to provide the ecosystem with R&D, production, and conformance testing functions.
The protocol conformance test cases were developed using the R&S CMW500 radio communication tester, which allows engineers to assess their NTN NB-IoT devices under realistic conditions, establishing a real-time, comprehensive connection with the simulated satellite network and testing the relevant signaling and RF scenarios in line with the 3GPP Rel. 17 specification.
The test solution emulates geosynchronous orbit (GSO) and geostationary orbit (GEO) as well as low earth orbit (LEO) constellations.
It helps engineers to verify NTN device challenges like time and frequency synchronization due to prolonged delay and Doppler effect, low Signal-to-Interference-plus-Noise Ratio (SINR), power saving mechanisms, satellite ephemerides, and GNSS acquisition, to name just a few of the core features.
