Deutsche Telekom Launches Multi-Orbit IoT Roaming Connecting GEO and LEO Satellite Networks

• Deutsche Telekom has become the first mobile network operator to enable IoT roaming across GEO and LEO satellite constellations alongside terrestrial cellular networks.
• The solution allows IoT devices to automatically transmit data globally using either satellite or mobile connectivity depending on availability.
• Commercial hardware validated seamless switching between terrestrial NB-IoT/LTE-M and satellite NB-NTN connectivity using a single SIM-based architecture.

Deutsche Telekom has reached a major milestone in global machine connectivity by becoming the world’s first mobile network operator to deliver multi-orbit IoT roaming, enabling devices to transmit data seamlessly through both geostationary (GEO) and low Earth orbit (LEO) satellite networks alongside traditional terrestrial cellular infrastructure. According to reporting published by IoT Business News, the development signals a shift toward globally unified IoT connectivity models that integrate satellite and cellular systems into a single operational framework.

The newly introduced capability ensures IoT devices can automatically switch between terrestrial mobile networks and satellite connections based on availability and environmental conditions, allowing uninterrupted communication across virtually any geographic region. This multi-orbit roaming capability has been successfully demonstrated using commercial NB-IoT hardware capable of operating across terrestrial networks, GEO satellites, and LEO constellations, highlighting the readiness of standardized hardware to support hybrid connectivity models at scale.

Deutsche Telekom’s system integrates its global IoT network, which supports NB-IoT and LTE-M connectivity, with satellite services provided by multiple partners. Skylo delivers coverage through geostationary satellites, while Sateliot and OQ Technology provide radio access through low Earth orbit satellite constellations. Jens Olejak, Head of Satellite IoT at Deutsche Telekom IoT, stated that the initiative establishes Deutsche Telekom as a global leader in delivering IoT connectivity across multiple satellite orbits both technically and commercially, reinforcing its strategic position in next-generation network infrastructure.

Further expanding its satellite capabilities, Deutsche Telekom confirmed that Iridium’s NTN Direct service will be made available to business customers during the second half of 2026. Iridium’s LEO satellite constellation, widely recognized for its global reach and reliability, will strengthen Deutsche Telekom’s non-terrestrial roaming footprint and extend coverage into previously unreachable environments.

The integration of multiple satellite orbit types brings distinct operational advantages. GEO satellites, positioned at approximately 36,000 kilometers above Earth, provide continuous and stable connectivity due to their fixed orbital position, making them suitable for applications requiring persistent communication. LEO satellites, by contrast, orbit much closer to Earth and move rapidly across the sky, enabling improved connectivity in high-latitude regions, mountainous terrain, and remote environments. Their lower orbital altitude also allows reduced latency and higher data throughput. Together, GEO and LEO networks create a resilient and flexible connectivity architecture capable of supporting IoT deployments even in isolated and infrastructure-limited locations.

Following its initial Early Adopter Program launched with Skylo in 2024, Deutsche Telekom expanded its satellite IoT development initiatives in 2025 by introducing a Multi-Orbit Early Adopter Program designed to accelerate hybrid connectivity solutions. The initiative brings together fifteen companies and five research institutions and is supported by technology partners including Sateliot, OQ Technology, Skylo, Nordic Semiconductor, and KYOCERA AVX. The program focuses on developing solutions that combine terrestrial cellular and satellite connectivity to ensure uninterrupted device communication regardless of geographic limitations.

Several practical applications emerging from the program demonstrate the operational value of multi-orbit connectivity. Spanish technology firm Datakorum has deployed a remote asset management system that enables monitoring and control of critical infrastructure assets across industries including water, energy, and oil and gas. The system allows operators to track real-time performance metrics such as pressure, quality, and system status, while also enabling remote control of field equipment such as valves and actuators. To ensure reliability in mission-critical environments, Datakorum’s solution uses LEO satellites as a backup connectivity layer and integrates terrestrial and satellite communication technologies within a single product powered by Nordic Semiconductor’s nRF9151 module.

Maritime connectivity represents another major use case. Slovenian company EMA, operating under the BlueTraker brand, provides vessel tracking solutions for fishing fleets and commercial ships. Its hybrid connectivity system combines mobile and satellite networks to ensure reliable transmission of vessel position and operational status even in open ocean environments. This capability is increasingly important as European Union regulations require vessel monitoring systems to be installed on smaller fishing vessels under twelve meters in length. Deutsche Telekom’s satellite NB-IoT technology offers a scalable and cost-effective connectivity solution that allows large fleets to remain connected without relying on specialized or proprietary equipment.

Satellite-enabled IoT also supports advanced artificial intelligence applications in remote environments. French company MountAIn has developed the IBEX autonomous AI vision sensor, which processes image data locally using edge AI technology to detect events such as forest fires, industrial safety risks, and infrastructure threats in real time. By leveraging satellite-based NB-IoT connectivity, the system ensures critical alerts and operational data remain accessible even in areas without terrestrial mobile coverage. Because only essential status and alarm data are transmitted, the solution remains efficient and compatible with narrowband network limitations.

From a technical standpoint, Deutsche Telekom and its partners validated multi-orbit connectivity using commercially available hardware compliant with global cellular standards. Nordic Semiconductor’s nRF9151 module represents the first 3GPP-compliant IoT module capable of supporting both terrestrial NB-IoT and LTE-M connectivity as well as non-terrestrial NB-NTN connections through GEO and LEO satellites. During testing, the module successfully established direct connectivity through Sateliot’s LEO satellites using a Deutsche Telekom SIM card, demonstrating seamless roaming between terrestrial and satellite networks using standard telecommunications architecture.

Connectivity through Skylo’s GEO satellite network is already operational for enterprise customers, while integration with OQ Technology’s LEO network has been successfully validated. Iridium’s LEO connectivity is currently undergoing integration and testing and is expected to become fully operational later in the year. For satellite communication, IoT devices must utilize antennas compatible with specific 3GPP satellite frequency bands, including n249, n255, and n256. Manufacturers such as KYOCERA AVX have already introduced antenna solutions supporting these bands, allowing device manufacturers to develop new satellite-enabled IoT products using existing components and standardized cellular architecture.

According to IoT Business News, Deutsche Telekom’s multi-orbit roaming solution reflects the growing convergence between terrestrial cellular networks and satellite communications. By enabling IoT devices to operate seamlessly across multiple connectivity layers using commercial hardware and SIM-based authentication, the company is helping establish a scalable and interoperable global framework for IoT connectivity. This architecture reduces dependency on proprietary satellite systems and allows enterprises to deploy IoT solutions with greater reliability, resilience, and geographic reach.

The ability to combine terrestrial cellular infrastructure with GEO and LEO satellite networks marks a significant advancement in global IoT deployment capabilities. As industries increasingly rely on connected sensors, automation systems, and real-time monitoring technologies, hybrid multi-orbit connectivity is expected to become a foundational component of next-generation digital infrastructure, enabling uninterrupted communication across remote industrial sites, maritime environments, and critical infrastructure networks worldwide.
