How HAPS Can Close Africa and Asia’s Connectivity Gap

Africa and Asia remain home to the world’s largest concentration of unconnected and underserved populations. Despite major investment in terrestrial mobile networks, fibre backbones, and low Earth orbit satellite constellations, vast areas still lack reliable, affordable connectivity. For governments, operators, and development finance institutions, the challenge is no longer simply whether to connect these regions, but how to do so sustainably and at scale.

High-Altitude Platform Stations (HAPS) are emerging as a compelling answer. Operating in the stratosphere, typically around 20 kilometres above Earth, HAPS can deliver wide-area connectivity with lower latency than geostationary satellites and broader reach than conventional terrestrial towers. For many markets across Africa and Asia, that combination makes HAPS uniquely relevant.

The scale of the connectivity gap

The digital divide across Africa and Asia is both a social and economic issue. According to the International Telecommunication Union, roughly 2.6 billion people globally remained offline in recent years, with the largest shares concentrated in developing markets. Sub-Saharan Africa continues to have the lowest internet usage rates in the world, while large rural populations across South and Southeast Asia remain either unconnected or poorly served.

Coverage maps often overstate practical access. A region may appear to have nominal mobile coverage, yet households still face weak signal quality, limited backhaul, high data costs, or frequent service outages. In many rural districts, the commercial case for additional towers is weak because of low population density, difficult terrain, and high energy and maintenance costs. Mountain ranges, deserts, forests, and island geographies further complicate deployment.

This matters economically. The World Bank and other multilateral institutions have repeatedly linked broadband access to gains in productivity, job creation, financial inclusion, and access to education and healthcare. In emerging markets, every incremental expansion in connectivity can unlock new digital services, from mobile banking and e-government to precision agriculture and telemedicine.

Why traditional infrastructure alone is not enough

Terrestrial infrastructure remains essential, but it is not always sufficient. Fibre is capital-intensive and slow to extend into remote regions. Mobile tower rollouts require land access, power supply, transport logistics, and ongoing maintenance. Even where networks exist, operators must still solve the backhaul challenge.

Satellites play an important role, especially for remote and maritime coverage, but different orbital architectures involve trade-offs in latency, terminal cost, and capacity economics. In many developing markets, operators and public-sector buyers are looking for complementary systems rather than a single technology solution.

This is where HAPS fit strategically. Positioned far above weather systems and commercial air traffic, HAPS can cover large areas from a single platform while maintaining line-of-sight links to the ground. Depending on payload and mission design, one HAPS can support telecommunications, observation, and emergency communications over a footprint that can span tens of thousands of square kilometres.

HAPS as a middle layer in the connectivity architecture

HAPS are best understood as part of a layered network architecture. They sit between terrestrial infrastructure and satellites, combining some of the strengths of both. Compared with ground towers, they dramatically expand coverage reach. Compared with geostationary satellites, they can offer far lower latency and more targeted regional capacity.

That makes them especially attractive for rural broadband extension, cellular backhaul, temporary capacity augmentation, and resilience applications. A HAPS platform can connect underserved communities without requiring a dense grid of new towers. It can also support mobile network operators by extending coverage economically into low-ARPU areas where conventional investment models struggle.

In Africa, this could be transformative for sparsely populated inland regions, cross-border corridors, mining zones, agricultural belts, and disaster-prone areas where resilience is critical. In Asia, HAPS have strong relevance for archipelagic states, mountainous terrain, and rapidly digitising rural populations. Countries such as Indonesia, the Philippines, India, and parts of Central Asia illustrate the kinds of environments where high-altitude platforms could provide a practical alternative or complement to terrestrial expansion.

Use cases with immediate policy and commercial relevance

The strongest case for HAPS lies in real-world applications rather than theoretical potential. Governments can use HAPS to accelerate universal service objectives without waiting years for full terrestrial build-out. Mobile network operators can deploy HAPS to improve rural coverage economics and strengthen network resilience during floods, cyclones, earthquakes, or conflict-related disruptions.

There is also a clear development angle. Schools and clinics beyond the reach of fibre can be linked to digital platforms. Farmers can gain access to weather intelligence, market prices, and agritech services. Border and maritime authorities can improve communications and situational awareness. Humanitarian agencies can restore connectivity rapidly after disasters when terrestrial infrastructure is damaged.

Importantly, HAPS are not limited to communications alone. The same stratospheric layer can support Earth observation, environmental monitoring, and security missions, improving the overall business case for deployment. Multi-mission capability is especially relevant in emerging markets, where public and private buyers often seek infrastructure that can deliver multiple policy outcomes.

What needs to happen next

The opportunity is significant, but scale will depend on execution. Regulatory frameworks must mature to support stratospheric operations, spectrum coordination, and cross-border service models. Public-private partnerships will be essential, particularly where governments want to align HAPS deployment with national broadband plans and universal access targets.

Cost discipline will matter as well. The winning HAPS models will be those that demonstrate persistent operations, reliable payload performance, and lower total cost of coverage than alternative options in targeted use cases. Investors and policymakers are increasingly focused on measurable outcomes: cost per square kilometre covered, cost per user connected, service availability, and deployment speed.

For Africa and Asia, the timing is increasingly favourable. Demand for digital access is rising, governments are under pressure to close rural coverage gaps, and the limitations of relying on only one infrastructure layer are becoming clear. HAPS offer a practical, flexible, and scalable way to bridge that gap.

A strategic opportunity for emerging markets

Closing the digital divide across Africa and Asia will require a mix of fibre, mobile networks, satellites, and new aerial platforms. HAPS are not a replacement for existing systems, but they could become a critical part of the connectivity toolbox for regions where terrain, economics, and urgency make conventional deployment difficult.

For stakeholders seeking faster, more resilient, and more inclusive connectivity, the stratosphere is no longer a distant concept. It is becoming an operational layer with meaningful commercial and public value.
