In‑Vehicle NTN Solution for Connected Vehicles

Conquering Coverage Gaps with In‑Vehicle NTN Connectivity

Mass market connected vehicle services depend primarily on terrestrial cellular networks. But road coverage is uneven, and large portions of global routes fall outside robust cellular planning. Non‑Terrestrial Networks (NTN) add a complementary layer—helping OEMs deliver baseline safety and telemetry everywhere, with premium infotainment delivered when bandwidth and policy allow.

Key expectations OEMs typically place on NTN include:

  • Basic safety and telemetry functions (e‑Call, road safety signaling, vehicle telematics).
  • Regional adaptability to comply with different government and regulatory requirements.
  • A path to premium services (infotainment) over satellite where appropriate.

Robust Connectivity for Next Generation Vehicles

A resilient connectivity layer supports operational continuity and customer experience—especially for fleets operating across rural roads, cross‑border routes, and remote corridors. With a robust architecture, OEMs can maintain service availability, reduce incidents tied to connectivity loss, and enable more consistent remote operations.

Unlocking Efficiency for Connected Fleets

Connected vehicle connectivity enables efficiency and cost control through remote diagnostics and continuous data flows. Typical demand drivers include:

  • Operational efficiency and reduced downtime through proactive service.
  • Continuous monitoring for vehicle health, driver diagnostics, and predictive maintenance.
  • Over the air maps and software updates to keep fleets current and secure.

Connected Cars Applications Beyond Traditional Telematics

Service requirements generally span three bandwidth tiers:

Narrowband

  • Telephony / e‑Calls
  • Road‑safety messaging
  • Remote services

Wideband

  • Fleet monitoring
  • Predictive maintenance & driver diagnostics
  • Maps & software updates

Broadband

  • In‑vehicle entertainment
  • Video conferencing
  • Gaming

HISKY’s In Vehicle NTN Solution

HISKY’s in vehicle NTN approach combines cellular, Wi Fi, and broadband satellite components to improve coverage and reliability for connected vehicles. The proposal builds on the commercially available SmarLITE terminal line—field proven terminals that provide a low risk route to in‑vehicle satellite connectivity, with a roadmap for cost reduction aligned to OEM requirements.
HISKY’s architecture is designed to be hardware and software agnostic to satellite networks, giving OEMs flexibility to choose GEO, MEO, or LEO constellations. A multi orbit approach from a single terminal can add an extra layer of service compliance and operational efficiency.

Connected Cars Solution Overview

Planning an NTN solution for connected cars is shaped by the expected density of simultaneously connected vehicles in each area. High bandwidth Ku/Ka satellite channels are often considered because they can support very large numbers of concurrent connections. Other planning variables include per vehicle data rate, antenna size and weight constraints, vehicle power consumption, and the selected satellite constellation.

Because platform parameters are still evolving, OEM antenna planning needs to start early—well before next generation tier 1 vehicle models finalize for the 2028–2029 timeframe.

Q&A

1. What does HISKY's in-vehicle NTN solution enable for OEMs?

It enables a resilient connectivity layer that complements cellular coverage, supporting baseline safety/telematics services broadly and enabling premium services where bandwidth and policy allow.

2. Why does HISKY emphasize network and constellation flexibility (GEOM/MEO/LEO)?

OEMs can align connectivity choices with regional coverage, latency, regulatory needs, and business models - without being locked into a single orbit strategy.

3. What factors matter most when planning an NTN architecture for connected cars?

Key factors include simultaneous-connection density, required bandwidth, per-vehicle data rate, antenna size/weight, power consumption, and the constellation design and availability in target regions.
