UK to Upgrade Onboard WiFi Across Trains Planes and Buses with Low Earth Orbit Satellites

Original publisher: The Conversation. The article explains how low Earth orbit satellite networks, led by Starlink and OneWeb, are poised to transform wifi on the move across trains, planes, buses and ferries. The UK government has announced a £57 million, five-year rollout to upgrade onboard wifi on mainline rail and expand coverage nationwide. By integrating LEO connections with existing terrestrial networks, service should become more reliable, with an onboard experience that can support streaming and cloud services by the early 2030s.

• Starlink and OneWeb promise near-global coverage and higher speeds for moving networks.
• The UK plans a £57 million five-year rollout to upgrade onboard wifi on mainline rail, with wider transport coverage.
• Hybrid networks will switch seamlessly between cellular and satellite links to reduce outages.
• Trains, planes, buses and ferries could see wifi availability rise toward the 90% target by the early 2030s.

Overview

Connectivity on the move is often unreliable due to rapid changes in signal strength and coverage. The article examines how low Earth orbit (LEO) satellite networks, notably Starlink and OneWeb, are being deployed to address these issues across multiple transport modes. The UK government has pledged a £57 million, five-year rollout to upgrade onboard wifi across nationalised rail services and to expand coverage for other transport modes. The aim is to combine satellite links with existing terrestrial networks to improve reliability and data speeds, enabling services such as video streaming and cloud-based applications while travelling.

LEO Satellite Networks and Onboard Connectivity

LEO satellites operate much closer to Earth than traditional geostationary satellites, allowing near-global coverage and higher-speed communications. Starlink, a SpaceX subsidiary, and OneWeb, part of the Eutelsat group, are highlighted as the leading systems capable of delivering continuous connectivity for transport users. The article notes that integrating LEO with existing terrestrial wifi networks can provide redundancy, seamless handovers, and fewer interruptions when a terrestrial link deteriorates.

Trains: Trackside vs Space-based Backhaul

Today, train wifi largely depends on aggregating terrestrial 4G and 5G signals along routes, and bandwidth is shared among passengers. This leads to degradation in rural areas and tunnels. The UK government has announced a £57 million, five-year rollout to provide LEO satellite connectivity across mainline rail. Trials on LNER, South Western Railway and Great Western Railway services in 2025 demonstrated the feasibility of satellite-enabled onboard wifi, with up to 1,400 trains expected to receive satellite connectivity. The rollout aims to lift onboard wifi availability from roughly half of UK train journeys to about 90% by the early 2030s. Integrating LEO systems with existing networks should enable automatic failover, reducing interruptions and improving user experience.

Planes: Inflight Internet and Satellite Handovers

In-flight wifi has grown since Lufthansa’s early 2000s service, and today about seven in ten airlines offer onboard connectivity. Air-to-ground (ATG) systems work well over land but are limited over oceans, while satellite-based connectivity is preferred for long-haul and transoceanic flights. LEO satellites have accelerated midair wifi, delivering speeds that can exceed 100 Mbps in some cases, but delays due to long signal paths and frequent satellite handovers persist. Technologies such as electronically steered antennas and AI-driven network management are expected to mature, further reducing disruption and enabling more terrestrial-like broadband experiences for most passengers.

Buses and Ferries: Hybrid Connectivity Across Land and Sea

Long-distance coaches typically rely on roof-mounted antennas and shared cellular networks, with performance limited by mobile coverage. The introduction of hybrid 5G-satellite systems promises more stable connectivity on rural routes and for operational services such as ticketing and CCTV. The article notes driver and passenger benefits, as well as trials led by Transport for Wales examining satellite-assisted rural connectivity. For ferries and cruise ships, satellite connectivity has historically been necessary at sea, but LEO systems have significantly improved wifi provision for vessels, with over 25,000 commercial and passenger ships using Starlink as of 2025. The trend suggests more reliable onboard wifi across sea routes as capacity expands and routing adapts to maritime conditions.

System Integration and Future Outlook

Across transport modes, the integration of LEO satellite connectivity with terrestrial wifi is presented as a path to seamless connectivity with fewer service interruptions. The ongoing rollout, broader adoption of LEO networks in air, rail, road and maritime sectors, and advances in antenna technology and AI-driven network management are framed as enabling a future where onboard wifi resembles terrestrial broadband for most passengers. The article concludes with optimism about the widespread availability of continuous wifi that supports streaming and cloud-based services, aligning with broader ambitions for ubiquitous, trusted connectivity on the move.
