Rohde & Schwarz has partnered with MediaTek to confirm the NTN NB-IoT protocol conformance check instances based on 3GPP 36.523-1 on MediaTek’s NTN IoT succesful MT6825 chipset. This achievement units the course for NTN system conformity approval a major step in bringing IoT gadgets primarily based on non-terrestrial networks (NTN) to the market and enabling connectivity on land, at sea, and within the air.
With the validation of the 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 similar to smartphone, client, automotive, agriculture, maritime, logistics, and mining. The discharge and improvement of those check instances is a serious stepping stone for future system certification mandated by trade committees similar to GCF and PTCRB.
This launch of NTN NB-IoT protocol check instances is predicated on 3GPP RAN#5 specs delivered by ETSI activity power MCC160. Intimately, the check instances confirm the modifications of MAC, RLC, and NAS layers, specializing in the system’s means to transmit GNSS knowledge effectively, handle a number of TACs, utilise Rel. 17 prolonged t-reordering, ship correct NAS reject causes and responses, deal with HARQ inside the NTN context underneath various DRX configurations, and precisely interpret timing advance from SIB31 contents.
Rohde & Schwarz has prolonged its NB-IoT answer with 3GPP Launch 17 NTN options to supply the ecosystem with R&D, manufacturing, and conformance testing features. 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 underneath practical circumstances, establishing a real-time, 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 system challenges like time and frequency synchronisation attributable to 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 only a few of the core options.
Over the previous 12 months, Rohde & Schwarz has collaborated with chipset distributors and developed intensive check instances for R&D validation of NTN NB-IoT Rel. 17 options.
