NTNSensors: 卫星 NB-IoT / eMTC 技术标准与微瓦级超低功耗工业物联网传感器

NTNSensors 制定天基窄带物联网 (NB-IoT) 与增强型机器类通信 (eMTC) 架构规范，将数以千万计运行在远洋海运、精准农业与集装箱物流中的超低功耗电池传感设备直连苍穹。

NTNSensors Massive Satellite NB-IoT (Rel-17/18) Ingest Pipeline

10-year battery life sensor node uplink to Low Earth Orbit cubesat constellation

Central System: 10-Year Autonomous Sensor - Single AA lithium cell operating NB-IoT Release 17 protocol

Network Nodes

  • 10-Year Autonomous Sensor
  • Micro-Strip Patch Antenna
  • LEO 16QAM Baseband Ingest Payload
  • Enterprise IoT Cloud Broker

Architectural Protocol Layers

  • Spaceborne PHY/MAC Layer (3GPP Rel-17 TS 38.300): Doppler compensation, HARQ disabling, and timing advance extension.
  • Orbital Mesh Routing (CCSDS / Delay-Tolerant Networking): Dynamic topology routing over intermittent laser crosslinks.
  • Regenerative Core Processing (OpenRAN / 3GPP CU-DU Split): Onboard user plane function (UPF) local breakout.

Key Metrics: < 18ms (LEO Orbit-to-Ground Roundtrip) | 100 Gbps (Optical Crosslink Throughput) | ±48 kHz (Doppler Shift Compensation) | 99.999% (Orbital Constellation Availability)
