Northern lights over the Nordic sky with Com4 circle graphics

Connected from fjord to open sea

Cellular at the coast, satellite offshore, one managed service.

Three worlds, one connectivity partner

Nordic maritime operations move between three worlds: busy ports with strong 5G, long coastlines where coverage comes and goes, and open sea with no cell towers at all. A single network type cannot cover that, so most operators end up juggling separate cellular and satellite contracts with no shared view.

Com4 combines cellular and satellite in one managed service. Devices use cellular and 5G in port and along the coast, and switch to satellite offshore, with monitoring and support from one Nordic partner.

Port and harbour

4G, 5G and Fixed Wireless Access for crew and operations broadband, cargo handling and CCTV.

Coast, fjords and fish farms

Multi-network cellular, LTE-M and NB-IoT for engine and sensor telemetry, aquaculture monitoring and buoys.

Open sea and offshore

LEO satellite (Starlink) and NTN satellite IoT for vessel tracking, remote assets and backup for critical links.

Why a specialist instead of a global carrier

Coverage built for the coast. Non-steered SIMs choose the strongest network along the coastline, instead of being locked to one operator.
Satellite in the same contract. Com4 is an official Starlink reseller and offers NTN satellite IoT, with failover between satellite and cellular.
Nordic know-how. 15 years connecting Nordic industry, from railway infrastructure to aquaculture technology.
Managed end to end. Routers, SIMs and monitoring from one supplier, with remote network management.

Case study

Remora Robotics: live video from the fish farm

Stavanger-based Remora Robotics builds AI-enabled underwater robots that clean the nets of Norwegian fish farms.

The robots send live video and operational data over Com4 Fixed Wireless Access on 4G and 5G to the cloud and an operations centre, where staff monitor them and improve their software.

Engine monitoring

A Com4 customer in Northern Europe streams vibration, temperature and pressure data from ship engines over Com4 cellular connectivity.

Cargo and container tracking

Cellular in port and satellite at sea, so shipments stay visible across the whole route.

Aquaculture

Sensors, cameras and robots at fish farms connected over coastal cellular and Fixed Wireless Access.

Crew and onboard broadband

High-speed connectivity with automatic failover between satellite and cellular.

A hybrid of cellular and satellite. Use multi-network cellular, LTE-M or 5G near the coast and in port, and LEO or NTN satellite offshore, ideally managed as one service.

Yes. Com4 managed solutions fail over between satellite and cellular, so critical data keeps flowing when one link drops.

Yes. Com4 is an official Starlink reseller and combines Starlink LEO connectivity with cellular in one managed service.

Usually over coastal cellular, with LTE-M or NB-IoT for low-power sensors and 4G, 5G or Fixed Wireless Access for robots and cameras. Satellite covers sites beyond reliable coverage.
