Rohde & Schwarz has partnered with MediaTek to confirm the primary NTN NB-IoT protocol conformance check instances in keeping with 3GPP 36.523-1 on MediaTek’s NTN IoT succesful MT6825 chipset. This achievement units the course for NTN gadget conformity approval – a big step in bringing next-generation IoT gadgets primarily based on non-terrestrial networks (NTN) to the market and enabling ubiquitous connectivity on land, at sea, and within the air.
With the profitable validation of the business’s first protocol conformance check instances for 3GPP Rel. 17 NTN NB-IoT, Rohde & Schwarz and MediaTek speed up adoption of non-terrestrial network-based IoT use instances spanning a number of sectors equivalent to smartphone, shopper, automotive, agriculture, maritime, logistics, and mining. The discharge and growth of those check instances is a significant stepping stone for future gadget certification mandated by business committees equivalent to GCF and PTCRB.
This primary launch of NTN NB-IoT protocol check instances is predicated on 3GPP RAN#5 specs delivered by ETSI activity drive MCC160. Intimately, the check instances confirm the adjustments of MAC, RLC, and NAS layers, specializing in the gadget’s capability to transmit GNSS information effectively, handle a number of TACs, make the most of Rel. 17 prolonged treordering, ship correct NAS reject causes and responses, deal with HARQ inside the NTN context below various DRX configurations, and precisely interpret timing advance from SIB31 contents.
Rohde & Schwarz has prolonged its market-leading NB-IoT answer with 3GPP Launch 17 NTN options to offer the ecosystem with R&D, manufacturing, and conformance testing capabilities. The protocol conformance check instances had been developed utilizing the R&S CMW500 radio communication tester, which permits engineers to evaluate their NTN NB-IoT gadgets below lifelike situations, establishing a real-time, complete reference to the simulated satellite tv for pc community and testing the related signaling and RF situations consistent with the 3GPP Launch 17 specification. The check answer emulates geosynchronous orbit (GSO) and geostationary orbit (GEO) in addition to low earth orbit (LEO) constellations. It helps engineers to confirm NTN gadget challenges like time and frequency synchronization as a result of extended delay and Doppler impact, low Sign-to-Interference-plus-Noise Ratio (SINR), energy saving mechanisms, satellite tv for pc ephemerides, and GNSS acquisition, to call just some of the core options.
Over the previous yr, Rohde & Schwarz has collaborated with main chipset distributors and developed in depth check instances for R&D validation of NTN NB-IoT Rel. 17 options.
