Deutsche Telekom $DTE (+2,36%) has reached a technological milestone and is the first mobile provider worldwide to introduce multi-orbit roaming for the Internet of Things (IoT).
For the first time, IoT devices can seamlessly transmit their data via terrestrial mobile networks as well as geostationary (GEO) and low-earth orbit (LEO) satellites. The solution has already been tested with a commercial IoT device and represents an important step towards globally available, fail-safe IoT connectivity.
》Satellites and mobile communications - combined for maximum range《
According to Telekom, the new multi-orbit concept is based on the combination of Telekom's global IoT network (NB-IoT and LTE-M) with several satellite partners.
Skylo covers the GEO orbit, while Sateliot and OQ Technology provide LEO connectivity. From the second half of 2026, Iridium's "NTN Direct" will add additional LEO capacity to the network.
GEO satellites will provide continuous coverage, while LEO satellites will enable low latency, higher data rates and better availability in mountainous and high latitude areas. Together, this creates a hybrid system that reliably reaches even the most remote regions.
Deutsche Telekom sees itself as a global pioneer in satellite-based IoT communication. "Deutsche Telekom is thus establishing itself as the leading global network operator offering IoT connectivity via multiple satellite orbits," says Jens Olejak, Head of Satellite IoT at Deutsche Telekom.
》Practical applications - from maritime security to critical infrastructure《
IoT solutions that combine terrestrial and satellite-based connections are currently being developed and tested as part of the Multi-Orbit Early Adopter Program.
15 companies and five research institutes are working together with partners such as Sateliot, OQ Technology, Skylo, Nordic Semiconductor and KYOCERA AVX.
》Technical validation with standard hardware《
One important aspect is the use of standard 3GPP-compliant hardware. The nRF9151 module from Nordic Semiconductor is the first cellular IoT module to support NB-IoT/LTE-M and NB-NTN via GEO and LEO. In tests, it successfully established connections to LEO satellites with a Telekom SIM. Antenna solutions for the necessary frequency bands n249, n255 and n256 are already available and make it easier for manufacturers to develop new devices.
With multi-orbit roaming, Deutsche Telekom is creating an IoT infrastructure that is global, flexible and highly fail-safe. It lays the foundation for new applications in industry, energy supply, logistics and security - wherever connectivity gaps previously existed.
