5G Satellite Networks: Sateliot’s Plan to Bring IoT to Areas Without Coverage

Millions of sensors, machines, and devices remain outside mobile coverage. Remote farmlands, secondary roads, shipping routes, wind farms, pipelines, railways, and reservoirs often operate “blind” because building terrestrial infrastructure isn’t cost-effective. Sateliot, a Barcelona-based company, aims to change this by delivering standard 5G from space to any IoT device currently out of signal.

Their ambitious plan involves a constellation of low Earth orbit (LEO) satellites capable of providing 5G connectivity for the Internet of Things using the same standard as terrestrial mobile networks. The goal isn’t to create a new protocol but to extend current 5G into space, allowing devices to connect seamlessly when ground networks are unavailable.

How Sateliot Works

Sateliot presents itself as the first operator offering fully integrated 5G IoT via satellite under the 3GPP standard. Its model relies on LEO satellites acting as “mobile antennas in space.” When an IoT device loses terrestrial coverage, the satellite takes over using the same bands and signaling technology.

The key difference from other satellite connectivity projects is that IoT devices don’t require specialized hardware to communicate with the constellation. Sensors, livestock GPS collars, or water meters can continue using their existing SIM cards and 5G or NB-IoT modems, making Sateliot’s network function as automatic satellite roaming.

Sateliot relies on 3GPP Release 17 for non-terrestrial networks (NTN), which defines how satellite networks should integrate with existing mobile infrastructure. This alignment ensures the solution is more than an experiment—it fits the roadmap of the global mobile ecosystem.

Architecture: LEO Satellites, 3GPP Compatibility, Direct Device Links

• LEO Satellites: Fly a few hundred kilometers above Earth, reducing latency and improving signal strength, enabling IoT devices to communicate without large antennas.
• 3GPP Integration: Devices treat the satellite network as another cell of their operator, simplifying mass deployment.
• Direct Device-to-Satellite Connection: Unlike other satellite solutions requiring gateways, Sateliot enables direct links, lowering costs and integration friction.

Use Cases: Agriculture, Logistics, Maritime, and Remote Infrastructure

• Smart Agriculture & Livestock: Real-time crop monitoring, livestock tracking, and machine fault detection in rural areas with irregular coverage.
• Logistics & Transport: Continuous tracking of vehicles, containers, and trailers even in tunnels, deserts, or at sea.
• Maritime & Fishing: Cost-effective satellite connectivity for small and medium boats for monitoring, safety alerts, and weather data.
• Rural Smart Cities & Infrastructure: Fire management, dam control, power line monitoring, and environmental sensors where fiber or mobile networks don’t reach.

Relevance for SMEs and Local Governments

Sateliot’s model doesn’t require heavy infrastructure investment. SMEs can deploy inexpensive sensors and pay only for the data volume. Municipalities and regional authorities managing water, waste, or civil protection can achieve comprehensive IoT coverage, supporting digitalization strategies previously limited to urban areas.

Growing Market: Competitors and Global Outlook

Sateliot operates in a niche focused on low-capacity, high-density IoT. Projects like AST SpaceMobile target consumer 4G/5G, while Starlink and OneWeb focus on broadband. European initiatives like IRIS2 complement this, offering high-security communications while Sateliot covers massive IoT. Telecommunications operators may adopt NTN networks to provide “unlimited” coverage without investing in towers or fiber.

Current Limitations

• Not broadband: suitable for small, periodic messages, not video or heavy data.
• Coverage still expanding: some areas may temporarily lack visibility.
• Variable latency: sufficient for IoT, not comparable to fiber or urban 5G.
• Launch schedule dependency: capacity improves as satellites are added.

For many IoT applications, these limitations are manageable, such as monitoring soil moisture versus real-time braking systems.

Outlook for the Next Three Years

If Sateliot and other companies execute their plans:

• Satellite numbers increase, improving service continuity.
• Agreements with mobile operators enable seamless satellite roaming.
• Sector-specific packages for agriculture, logistics, energy, and environment.
• Integration of satellite connectivity with local edge computing in devices.

The advantage for businesses lies in deploying solutions previously impossible due to lack of coverage, turning previously “blind” areas into connected environments.
