# The Rise of Satellite IoT: How Space-Based Connectivity Is Reshaping the Internet of Things
## A Connectivity Revolution Beyond the Ground
The Internet of Things has long relied on terrestrial networks — cell towers, Wi-Fi hotspots, and low-power wide-area gateways — to keep connected devices communicating. But those networks cover only a fraction of the planet. Roughly 90 percent of Earth’s surface remains beyond the reliable reach of ground-based connectivity, leaving vast stretches of ocean, desert, forest, and rural highway disconnected from the smart infrastructure that modern industry depends on.
Satellite IoT has emerged as the bridge over that gap, and the numbers tell a compelling story. The global satellite IoT subscriber base crossed the 7 million mark in 2025, and analysts project that figure will balloon to 42 million connections by the end of the decade — a trajectory representing a compound annual growth rate of over 43 percent. What was once a niche connectivity solution built around proprietary hardware and dedicated terminals is rapidly becoming a mainstream extension of the broader IoT ecosystem.
## From Standalone to Shared: The Technology Convergence
One of the most significant shifts in the satellite IoT landscape is the move away from purpose-built communication hardware. In the early days of satellite IoT, deploying a connected asset in a remote location meant investing in a specialized terminal — a device with its own radio, antenna, and subscription plan that operated on a frequency and protocol designed exclusively for space-to-ground links. That created friction. Manufacturers had to maintain separate product lines for devices that needed satellite coverage versus those that operated on terrestrial networks.
That picture is changing fast. A new generation of satellite constellations is embracing radio standards already embedded in billions of terrestrial devices. Several operators are building networks around 3GPP-compliant 4G and 5G protocols, the same cellular technologies that power smartphones and industrial sensors worldwide. Others are constructing their architectures around LoRa, the low-power wide-area modulation that has become a staple of agriculture, utilities, and smart-city deployments. One notable player is even enabling direct satellite communication from standard Bluetooth devices, sidestepping the need for any additional radio hardware on the end user’s side.
This convergence matters because it reshapes the economics of remote connectivity. When a device can use the same chipset and antenna architecture to communicate through both a nearby cell tower and a satellite overhead, manufacturers no longer need to design two entirely separate products. The complexity doesn’t disappear — antenna tuning, power management, and regulatory certification still require careful engineering — but it shifts. Instead of satellite being an entirely different product category, it becomes a feature that can be layered onto existing IoT hardware designs.
## A Crowded and Diversifying Field
The satellite IoT market was once dominated by a handful of well-known operators. Iridium, with over 2.1 million subscribers, remains the largest player, having grown its installed base by roughly 6 percent in the most recent reporting period. ORBCOMM served approximately 950,000 satellite IoT subscribers across its own infrastructure and that of its partner Viasat at the close of 2025, while Globalstar reported approximately 540,000 subscribers.
But the competitive field has expanded dramatically. Industry tracking identifies more than 40 active satellite IoT operators, and a significant portion of those are newcomers. Companies like AST SpaceMobile, Geespace, Hubble Network, Kinéis, Lynk, Myriota, OQ Technology, Plan-S, Sateliot, Skylo, and Starlink are all vying for a share of the market, and many are deploying low-Earth-orbit constellations that promise lower latency and higher bandwidth than traditional geostationary satellites.
This influx of new entrants has accelerated innovation, particularly in the area of hybrid connectivity. Rather than treating satellite as a standalone service, many operators are positioning their networks as a complement to terrestrial infrastructure — a seamless extension that kicks in when a device moves out of range of cell towers or Wi-Fi access points.
## Partnerships With Mobile Operators and MVNOs
Perhaps the clearest signal of satellite IoT’s growing integration into mainstream connectivity is the surge in partnerships with mobile network operators and mobile virtual network operators. Skylo has been especially active in this space, forming alliances with major carriers and connectivity providers including Deutsche Telekom, Verizon, Telefónica, Orange, Vodafone, KPN, Tele2, Soracom, floLIVE, emnify, and BICS. Other satellite operators pursuing similar mobile ecosystem partnerships include AST SpaceMobile, Iridium, OQ Technology, Sateliot, Starlink, Terrestar, and Viasat.
These collaborations are significant for a few reasons. First, they give satellite operators access to the massive distribution networks and enterprise customer bases that mobile operators have spent decades building. Second, they allow MVNOs and connectivity providers to offer their clients a unified connectivity experience — one SIM, one platform, one bill — that covers both urban environments with rich terrestrial coverage and remote locations where only satellite can reach. Third, they validate the idea that satellite IoT is not a separate industry but an integral part of the IoT connectivity value chain.
## The Enduring Power of Coverage
Beneath all the technological convergence and market expansion lies a simple, persistent truth: coverage is what makes satellite IoT valuable. Terrestrial networks are built where people and infrastructure already exist. They follow roads, populate cities, and cluster around economic activity. The places they don’t reach — the open ocean, the remote mine site, the cross-continental pipeline, the overseas shipping lane — are often the places where connected devices are most needed for safety, efficiency, and operational visibility.
Asset tracking is a particularly strong use case for this dynamic. A container shipped from Shanghai to Rotterdam might spend most of its journey within range of cellular networks, only to enter areas of open ocean where satellite becomes the sole means of communication. The emerging best practice in these scenarios is not to choose one technology over another but to build devices that can intelligently switch between connectivity sources as availability changes. This hybrid approach — sometimes called multi-modal connectivity — is becoming a defining characteristic of next-generation IoT hardware.
## What the Numbers Mean for the Industry
Projecting 42 million satellite IoT connections by 2030 represents more than a linear expansion of an existing market. It signals a structural shift in how the IoT industry thinks about connectivity. For enterprise decision-makers, the relevant question is no longer simply “should we use satellite or terrestrial?” but rather “how do we build deployments that can adapt to whatever network is available at any given moment?”
The operators, device manufacturers, and connectivity platforms that can answer that question — by creating seamless, standards-based hybrid solutions — are likely to capture the lion’s share of the growth ahead.
