MWC: Deutsche Telekom and European Space Agency strive for maximum resilience

Deutsche Telekom and European Space Agency strive for maximum resilience

  • Joint initiative for more secure networks with borderless connectivity
  • Memorandum of understanding signed to improve integration of satellites
  • DT achieves worldwide first 5G-connection from stratosphere backhauled over Intelsat's satellite network

Many people describe their digital state in everyday life as “always on”. Natural disasters in recent years have shown how easily this everyday life can get out of control. Most recently, the earthquake in Turkey. In such a situation, survivors would have decisive advantages if they were still “always on”. But in an emergency, the infrastructure on the ground is often just as affected by the consequences as the people.

The European Space Agency (ESA) and Deutsche Telekom will jointly work to enable seamless connectivity from terrestrial networks, from the sky or from above. At Mobile World Congress 2023 in Barcelona, the partners agreed in a memorandum of understanding (MoU) to work together on the hybrid networks of the future. Their plan: more resilient and secure connectivity solutions to answer future communication needs. It is especially important in the event of possible disruption to parts of the network technology on the ground. In such a case a non-terrestrial network from satellites or from the stratosphere could be used to seamlessly maintain contact with the smartphones of the affected people. Or from rescue teams on the ground, taking over from the conventional ground infrastructure that has been affected by a disaster.

“We have a clear ambition: to bring connectivity to everyone at any time and anyplace. Connection alternatives, such as satellites, play a crucial role in complementing our terrestrial network to ensure service continuity. The collaboration with ESA is an important step in laying the technological foundations for a strengthened network resilience based on the combination of terrestrial and satellite communications. This will improve the accessibility of our network for anyone who needs to stay connected,” said Claudia Nemat, Member of the Deutsche Telekom Board of Management responsible for Technology and Innovation.

Javier Benedicto, acting ESA Director of Telecommunications and Integrated Applications, said: “ESA supports the future of connectivity where satellites are integrated with terrestrial technologies to provide ubiquitous, seamless and secure connectivity for all. We are delighted to have formed a partnership with Deutsche Telekom to advance relevant technologies in this field. ESA supports European and Canadian industries to foster innovation and compete globally.”

World premiere: 5G all the way to space and back

Together with partners such as the satellite specialists at Intelsat, Deutsche Telekom has demonstrated the technical feasibility of this new challenge. They have already been testing the use of various types of antenna platforms in the stratosphere for years. In the process, Deutsche Telekom has shown that connection from the ground is increasingly possible with conventional smartphones and, for example, 5G technology.

Now Deutsche Telekom and its partners have taken a decisive step forward. During tests in Istria (Croatia), an orchestrated 5G connection was achieved seamlessly across different network layers into the stratosphere, space and back for the first time worldwide. In the process, the mobile service provided from the stratosphere took the backhaul path via satellite and its ground infrastructure to the backbone network or directly to the ground station. The data transfer started with a standard 5G cell phone over a 20 MHz channel. In the airspace above Pula, Deutsche Telekom achieved data speeds of up to 200 Mbit/s in February 2023.

This proves that hybrid communications over terrestrial and non-terrestrial networks can provide the highest level of resilience. Intelsat has a proven track record of providing connectivity in the wake of natural disasters. Now, using a satellite network – like Intelsat's multi-orbit, unified network, provides exactly the fallback option that will help victims of disasters in extreme situations. Intelsat’s multi-orbit solution allows for seamless, uninterrupted use while switching from high altitude platform stations (HAPS) to geosynchronous satellites if the situation requires change. Requesting help, giving a report on the situation on the ground, and thus facilitating the rescue forces' operations - all this now seems more feasible in extreme cases.

Stitching the various layers of networks

Non-terrestrial networks (NTNs) are communications networks with components in space and in the air. These include antenna platforms in the stratosphere, known as HAPS. These can be free-floating high-altitude balloons, airships or powered gliders that can even run on solar energy and hydrogen power. In space, on the other hand, it is satellites, such as the Intelsat-38 used in the trial. To integrate these new forms of networks into existing networks, these disparate communications technologies must be orchestrated. They thus become multi-dimensional networks, with seamless switch across different layers spanning the space, the sky and the earth, is the ultimate ambition of Deutsche Telekom with this partnership.

About the European Space Agency

The European Space Agency (ESA) provides Europe’s gateway to space. ESA is an intergovernmental organisation, created in 1975, with the mission to shape the development of Europe’s space capability and ensure that investment in space delivers benefits to the citizens of Europe and the world.

ESA has 22 Member States: Austria, Belgium, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland and the United Kingdom. Latvia, Lithuania, Slovakia and Slovenia are Associate Members.

ESA has established formal cooperation with four Member States of the EU. Canada takes part in some ESA programmes under a Cooperation Agreement. By coordinating the financial and intellectual resources of its members, ESA can undertake programmes and activities far beyond the scope of any single European country. It is working in particular with the EU on implementing the Galileo and Copernicus programmes as well as with Eumetsat for the development of meteorological missions.
