What Is World Mobile’s Blockchain Powered Stratospheric Connectivity?

World Mobile’s stratospheric connectivity is a high-altitude telecommunications system that uses hydrogen-powered aircraft to deliver 5G internet directly to mobile devices. Operating at 60,000 feet, each aircraft covers 15,000 square kilometers and integrates into World Mobile’s blockchain-powered decentralized network.

The project, developed in partnership with Indonesia’s Protelindo, is designed to bring coverage to regions where terrestrial and satellite infrastructure is limited or uneconomical.

A New Layer in the Connectivity Stack

World Mobile Stratospheric is the company’s aerial network layer, adding to its existing decentralized physical infrastructure network (DePIN). While World Mobile’s ground-based AirNodes provide local coverage, the stratospheric layer acts as high-altitude backhaul, extending service into rural or hard-to-reach areas.

The aircraft are based on over a decade of research from Stratospheric Platforms Ltd. (SPL), whose technology was tested in the UK, Germany, and the Middle East with peak speeds of 90 Mbps and latencies as low as 1 millisecond.

Technical Design and Capabilities

The hydrogen-powered, fixed-wing aircraft has a 56-meter wingspan and weighs about four tons. Key specifications include:

• Operating altitude: 60,000 feet (above weather systems and turbulence)
• Coverage area: 15,000 sq km per aircraft (replacing ~500 terrestrial towers)
• Antenna system: 3-meter phased-array 5G antenna with 450 steerable beams
• Throughput: Up to 100 Gbps
• User capacity: 500,000 direct-to-handset connections without additional hardware
• Latency: Around 6 milliseconds in operational mode

Powered by liquid hydrogen, the aircraft produces zero carbon emissions during flight, releasing only water vapor. Each drone can stay airborne for nine days before refueling.

Proven Trials Before Deployment

Before World Mobile’s acquisition of SPL assets, demonstration flights validated the aircraft’s stability, antenna performance, and ability to deliver low-latency connections. Trials with BT (UK), Deutsche Telekom (Germany), and Middle Eastern operators confirmed real-world viability.

These results reduce technical uncertainty, enabling a more confident path toward scaled deployment.

Environmental and Economic Benefits

Compared to conventional towers and satellite launches, the platform has a 99% lower environmental impact during operations, per World Mobile. Hydrogen fuel minimizes carbon emissions, while the aircraft’s wide coverage reduces the need for extensive ground infrastructure.

From a cost perspective, World Mobile estimates that data delivery is up to 18 times cheaper per gigabyte than satellite-based systems.

Partnership With Protelindo

Protelindo, Indonesia’s largest digital infrastructure provider, brings operational scale with tens of thousands of telecom towers across the country. Indonesia’s geography — a vast archipelago with thousands of islands — poses unique coverage challenges, making aerial systems an effective complement to existing terrestrial networks.

World Mobile contributes its blockchain-based incentive model, powered by the World Mobile Token (WMTx), which rewards community participation in network growth and maintenance.

Regulatory and Technical Challenges

Deploying high-altitude platforms involves:

• Radiation shielding: Protecting electronics from cosmic radiation
• Thermal control: Managing extreme temperature differences at 60,000 feet
• Aviation compliance: Meeting FAA and EASA safety and certification standards
• Flight permits: Securing approval for unmanned aerial vehicle (UAV) operations

The aircraft must also maintain structural integrity and fuel efficiency despite the demands of extended flight and environmental exposure.

Competitive Landscape

World Mobile’s approach competes with both terrestrial and space-based systems:

• Helium Mobile – Decentralized wireless nodes combined with telecom partnerships
• Starlink – Satellite-based internet targeting remote areas with no cellular coverage

World Mobile targets regions with higher mobile user density, offering direct-to-handset connectivity without the need for satellite dishes or special hardware.

Beyond Telecommunications

While mobile connectivity is the primary goal, the aircraft’s modular payload design allows for other applications, such as:

• Environmental monitoring
• Disaster recovery operations
• Public safety surveillance
• Scientific research over remote terrain

These functions leverage the aircraft’s endurance and stable high-altitude positioning.

Roadmap and Next Steps

The joint venture’s immediate focus includes:

• Conducting live demonstration flights with scaled-down antenna systems
• Working with regulators for certified operational approval
• Selecting high-impact early deployment zones in Indonesia, the U.S., and underserved regions globally

Commercial rollouts will prioritize areas where ground network expansion is slow or uneconomical.
