NTN Direct-to-Device: Подключение обычных смартфонов к низкоорбитальным спутникам

NTNComm развивает технологии связи со смартфоном напрямую со спутника, рассчитывая бюджет радиолиний для антенн 0,2 Вт, спектр 3GPP Band 25/70/65 и протоколы телеметрии IoT-NTN.

NTNComm System Architecture

Core architectural topology and protocol interaction of ntncomm.com

Central System: D2D Space Link - Direct-to-Cell

Network Nodes

  • Standard Phone
  • Giant LEO Reflector
  • S/C-Band MSS
  • NB-IoT Carrier
  • Emergency SOS

Architectural Protocol Layers

  • User & Terminal Access Layer (3GPP Rel-17/18 NR-NTN & IoT-NTN): Direct communication from smartphones and IoT sensors to satellites
  • Space-Borne Radio Access (gNodeB / Transponder) (Regenerative Digital Payloads & Bent-Pipe Transparent Processing): In-orbit demodulation, digital beamforming, and spectrum channelization
  • Inter-Satellite Mesh & Space Transport (Optical Inter-Satellite Links (OISL) & 60 GHz V-Band Cross-Links): Autonomous multi-hop laser packet routing in vacuum at the speed of light
  • Ground Teleport & Core Cloud Ingress (High-Throughput Q/V-Band Gateways & Optical Ground Stations): Terabit feeder link downlinks connected directly to cloud hyperscalers

Key Metrics: 100 Gbps+ (Optical Cross-Link Bandwidth) | <25 ms (LEO Propagation Latency) | ±50 kHz (Doppler Shift Compensation) | 99.999% (Constellation Transport SLA)
