In today’s economy, reliable broadband internet access is crucial for using online government services and participating in eCommerce. While affordable connectivity is common in many urban areas, many rural and remote communities still lack adequate options.
Demand for high-speed internet over both fixed and mobile networks has surged, but worldwide access remains uneven. Despite ongoing telecom network upgrades and expansion, an estimated half of households globally still do not have access to fixed broadband services.
Low Earth Orbit (LEO) satellite constellations offer a promising path to improve broadband penetration in underserved regions. Market research projects that the satellite broadband market will grow from an estimated 3.5 million subscribers in 2021 to around 5.2 million by 2026, expanding at roughly 8% compound annual growth and generating billions in service revenue.
Satellite broadband service market development
LEO satellites are expected to play an increasingly important role in delivering broadband. High Throughput Satellite (HTS) LEO systems can deliver multi-gigabit capacity per satellite, and operating at altitudes roughly between 800 and 1,600 kilometers reduces round-trip latency to approximately 30–50 milliseconds. That lower latency enables usable support for applications such as live video streaming that are sensitive to delay.
By contrast, Geostationary Earth Orbit (GEO) satellites operate at about 36,000 kilometers above Earth and have historically been used to bring broadband to homes and businesses in remote locations where terrestrial deployment is difficult. Although GEO satellites can offer sufficient throughput for many services, their high altitude results in latency around 600 milliseconds, which limits support for latency-sensitive applications.
SpaceX was among the first operators to deploy LEO-based consumer broadband at scale, launching the Starlink service in 2020. Starlink has offered residential plans with speeds around 100 Mbps and unlimited data tiers, and the company has launched thousands of LEO satellites with the goal of serving hundreds of thousands of homes and businesses in the U.S. and expanding internationally.
Other operators have also entered the LEO market. OneWeb and Telesat have launched satellites targeting enterprise and government customers. Amazon’s Project Kuiper received regulatory approval to deploy a LEO constellation, and the company plans future launches to bring its service online.
As global internet connectivity spreads, satellite broadband will remain an important complementary segment of the wireless broadband market. It faces competition from terrestrial fixed and mobile networks, especially as LTE and 5G rollouts expand and provide fixed wireless access (FWA) options. However, the cost and time required to deploy terrestrial infrastructure often limit coverage in sparsely populated and remote areas, preserving a role for satellite solutions.
Outlook for satellite broadband service growth
Flexible service plans and pricing strategies will be important to broaden adoption across developed and emerging markets. Initial hardware subsidies may be necessary to accelerate take-up, and higher adoption rates will help drive economies of scale that eventually lower equipment costs.
Takeaway: Having followed the LEO satellite communications sector for decades, including work on early projects such as Iridium, I’ve seen significant technological progress across satellite systems and related space technologies. Continued advances in LEO broadband constellations should make reliable internet access more available to people living in under-served and unserved areas worldwide.
