Can aircraft flying at the edge of space solve one of humanity's most persistent problems?
Nearly 3 billion people still lack reliable internet access, not because the technology doesn't exist, but because conventional infrastructure economics make it impossible to justify cell towers in remote villages, disaster zones, or across archipelagos stretching thousands of kilometers. World Mobile Stratospheric thinks the answer isn't on the ground or in orbit. It's in between, at 20,000 meters, where hydrogen-powered aircraft could act as flying cell towers covering areas the size of small cities.
The company announced a partnership with British aircraft manufacturer Britten-Norman to prove the concept works. In mid-2026, a modified Islander aircraft will take flight equipped with phased-array antennas, testing whether a single platform can deliver real-time 5G coverage across a 15-kilometer radius. If successful, the demonstration sets the stage for a full stratospheric network capable of connecting 500,000 people simultaneously from a single aircraft operating where commercial jets cruise, sustained by hydrogen fuel cells running 24 hours a day.
This isn't just another connectivity announcement. This is about rewriting the physics and economics of how networks get built.
The Infrastructure Problem That Won't Go Away
Building traditional mobile networks requires a brutal calculation. Each cell tower costs between $150,000 and $500,000 to deploy, needs reliable power, demands fiber or microwave backhaul, and serves a limited geographic area. In Manhattan, where thousands of subscribers pack into every square kilometer, the math works. In rural Indonesia, mountainous Peru, or post-disaster zones where infrastructure lies in ruins, it doesn't.
Satellites operating in low Earth orbit fly too high. At 550 kilometers altitude, the signal delay becomes noticeable, power requirements surge, and the cost per connection remains stubbornly high even as SpaceX launches thousands of Starlink satellites. According to the GSMA, bridging the global connectivity gap would require over $700 billion in infrastructure investment using conventional methods. That money isn't coming, which is why the gap persists year after year.
Stratospheric platforms operate in a Goldilocks zone. High enough to cover vast areas with a single platform, low enough to maintain signal strength and minimal latency. At 20,000 meters, an aircraft equipped with the right antenna system can theoretically cover what would require 50 to 100 ground-based cell towers. The coverage area becomes the aircraft's service zone, moving where needed rather than staying fixed to one location.
World Mobile Group, WMS's parent company, has spent years building ground networks across Africa using blockchain-based infrastructure sharing models. They've seen firsthand what happens when connectivity arrives in places that never had it. Schools gain access to educational resources. Health clinics connect to telemedicine networks. Small businesses join the digital economy. The impact isn't incremental, it's transformative, which makes the economics of reaching the next billion users not just a business question but a development imperative.
Why the Islander Becomes a Flying Laboratory
Britten-Norman's Islander wasn't designed for telecommunications. The twin-engine utility aircraft has been flying since 1965, operating from short runways and working in conditions that would ground more sophisticated planes. Over 1,300 have been built, serving everywhere from Caribbean island-hoppers to military surveillance platforms.
Strapping experimental phased-array antennas onto an aircraft and expecting it to maintain stable 5G connections while flying at altitude isn't trivial engineering. "The Islander serves as a proven, certified platform for innovative applications, with our experienced teams ensuring seamless integration of novel technologies while maintaining the highest safety standards," said Mark Shipp, Technical Director and Head of Design at Britten-Norman.
The 2026 demonstration will test whether phased-array antennas can electronically steer beams toward users on the ground, serving thousands of simultaneous connections. Testing happens in cooperation with BT at their Adastral Park research facility near Ipswich. The demonstration aircraft uses conventional turboprop engines because the goal is validating the radio systems first. The hydrogen-powered stratospheric aircraft comes later.
The Stratospheric Vision: Networks That Float
Picture hydrogen-powered fixed-wing aircraft operating in shifts at altitudes up to 20,000 meters, each one covering a service area previously requiring massive ground infrastructure. When one aircraft needs refueling, another takes its position, maintaining continuous coverage. Each platform supports up to 500,000 direct-to-handset connections, half a million regular smartphones pulling data, making calls, accessing the internet simultaneously from a single aircraft.
The disaster response application reveals why this matters. When hurricanes, earthquakes, or floods destroy ground infrastructure, communications go dark exactly when they're needed most. An aircraft-based system operating from short runways could restore mobile networks within hours instead of weeks.
Indonesia's geography makes this especially relevant. The country spans more than 17,000 islands across 5,000 kilometers. Connecting that archipelago with submarine cables and island-by-island cell tower deployment costs billions and takes decades. Stratospheric platforms that can reposition between islands fundamentally change the connectivity equation.
Blockchain Meets the Stratosphere
WMS isn't planning to own and operate every aircraft as a traditional telecom company would. They're planning to apply decentralized physical infrastructure networks (DePIN) to stratospheric platforms. DePIN uses blockchain economics and token systems to enable distributed ownership of physical infrastructure. World Mobile Group pioneered this model for ground-based networks in Africa, where local operators deploy and maintain equipment while earning from network usage.
"World Mobile Stratospheric will ultimately realize the use of DePIN networks using a sharing economy model from the stratosphere," Deakin said. Applying this to aircraft at 20,000 meters means potentially dozens or hundreds of operators could deploy stratospheric platforms, coordinate coverage, and participate in network revenue based on their contribution. The model distributes capital requirements while creating economic incentives for expanding coverage to underserved areas where traditional operators won't go.
The Battlefield: Who Else Is Racing to the Stratosphere
Google spent years and reportedly over $1 billion on Project Loon, using high-altitude balloons to provide connectivity before shutting the program down in 2021. The technology worked but the economics didn't. Airbus developed Zephyr, a solar-powered unmanned aircraft that set endurance records flying at stratospheric altitudes. HAPSMobile, backed by SoftBank and AeroVironment, continues developing solar-powered platforms for mobile coverage.
WMS's hydrogen approach differs in crucial ways. Solar HAPS can only operate during daylight and have limited power budgets. Hydrogen fuel cells provide consistent power 24 hours a day and higher capacity for supporting hundreds of thousands of connections simultaneously. The tradeoff is operational complexity: hydrogen production, transportation, and refueling infrastructure doesn't exist at scale.
The market comes down to cost per connection and operational reliability. Stratospheric platforms aim to occupy the middle ground: better than satellites for capacity and latency, better than ground networks for coverage and deployment speed.
Final Thoughts: The Gap Between Vision and Execution
The vision is extraordinary: aircraft at the edge of space beaming 5G to half a million people simultaneously, coordinated through blockchain economics, connecting billions still offline while providing disaster response resilience. It's the kind of vision that either changes the world or becomes another cautionary tale about ambition exceeding capability.
Skepticism is warranted. Project Loon proved the technology could work before proving the economics couldn't. But WMS brings advantages Loon didn't have. World Mobile Group has operational experience deploying alternative connectivity models. Protelindo brings Indonesian market access. The hydrogen-powered approach addresses limitations that constrained solar platforms. And the DePIN model potentially unlocks capital and operational scale that centralized deployments never achieve.
If WMS can translate vision into operational reality, starting with successful 2026 flight tests and progressing to hydrogen-powered stratospheric operations with DePIN economics, they won't just build a telecommunications company. They'll prove that the most persistent infrastructure problems can be solved by changing not just the technology but the entire model of how networks get built, funded, and operated.
The race is to the stratosphere. The finish line is connecting the next billion people.
