The whole world …

The news, the weather report, and the biggest dictionary in the world. All our favorite series, our entire music collection, and the contents of our bookshelf. Family photos and posts from our loved ones. Street maps from all over the world. What do all these things have in common? Thanks to the worldwide web, we have them with us all the time – no matter where we are.

... together online

Just a few years ago, this was all inconceivable. And today? Now, it’s hard for anyone to imagine anymore how everyday life once functioned without constant access to the internet. Today, (almost) all of us live, learn, and work on the web. At Deutsche Telekom, our aim is to make sure that everyone can #TAKEPART. And the basis for that is fast and high-performance internet access. That’s why we invest billions each year in network expansion – in 2020, the figure was some EUR 17 billion across the Group. In Germany, we have been the largest investor in this area for years.

In particular, the coronavirus pandemic has shown that our investments have really paid off. Despite the heavy increase in data traffic, our network has remained stable – a strong signal, as it is particularly in times of crisis that we see how important the internet is for us all.


We’re working hard on the network rollout in both the fixed and mobile networks. And we will live up to our responsibility for Germany’s digital future.

Covering some 575,000 kilometers (end of 2020), we operate the largest fiber-optic network in Europe.

Superfast fiber-optic cables

We aim to provide as many people as possible with fast internet lines – whether they live in cities or in rural areas. In the fixed network we rely on fiber optics: Covering some 575,000 kilometers (end of 2020), we operate the largest fiber-optic network in Europe. Depending on the technology, the cables are taken right into the home (fiber to the home) or as far as the gray street cabinets on the curb (fiber to the curb). img .

This requires a lot of time and money – each kilometer of fiber-optic cable costs an average of 70,000 euros – so connection to the fiber-optic network is not economically viable everywhere. Our solution in such cases is a hybrid connection that combines the speed of a DSL line with that of an LTE-based mobile connection to increase the broadband speed. Funding programs at national or state level are a further possibility for cost-effective expansion. Just like other companies, Deutsche Telekom also applies for such funding. A new cable-laying method called trenching img has the potential to make the build-out both faster and less expensive. We are currently in dialog with city and municipal authorities to ascertain where this method could be used.

Through the air

We wish it were a thing of the dim and distant past – the mobile coverage gap. By the end of 2020, we were able to provide 98.7 percent of households in Germany with fast LTE – more than any other network provider. The remaining gaps are to be filled as quickly as possible. To achieve that, we aim to build more than 2,000 new mobile sites each year. That’s sometimes easier said than done, though, because building or legal regulations mean masts cannot be erected everywhere they are required. To close the final gaps in the mobile network, we are using various levers:

Sharing masts

To expand the network infrastructure more quickly and cost-effectively, we are sharing mobile masts with our competitors. In 2019, together with Telefónica Deutschland and Vodafone, we announced that we would jointly set up and use up to 6,000 new mobile sites.

Hunting down dead zones

In 2019, we launched the “Hunting down dead zones” campaign, which allowed municipalities with an LTE coverage gap to apply for one of 100 new mobile masts. The campaign’s first mobile masts are already in use in the winning municipalities. A further 180 applications are to be connected in the coming years as part of the planned expansion program.

Climate neutral

In 2019, we set up a mobile mast for the first time in the Bavarian town of Dettelbach that uses carbon-neutral electricity from a fuel cell. Power supply is often a problem at remote locations. This solution will be able to help in the future to close mobile coverage gaps in a climate-friendly way.

By the end of 2020, more than two thirds of the German population had access to the Deutsche Telekom 5G network – in 4,700 cities and municipalities. You can see where 5G is already available at

5G on its way

Up to 100 times faster than LTE? That’s 5G, the new mobile standard. 5G is the basis for many future concepts, such as concepts, such as autonomous driving, smart cities, Industry 4.0, and virtual reality. That’s because they all require high-performance, fail-safe internet connections that enable data transmission in real time. To make Germany a 5G country as soon as possible, we have set ourselves a clear goal: We plan to cover 99 percent of the population and 90 percent of the country with 5G by 2025.

What we need for 5G

Rolling out a new technology over a wider area is always pioneering work. For us as a society to benefit from the advantages of the new technology as quickly as possible, three things in particular are needed:


For 5G, we are initially using 4G locations. You could say that 5G is “piggybacking” on LTE. But to do this, the existing infrastructure needs an upgrade – from replacing old components to switching to new system technology. As a whole, the mobile communications network will also be further expanded with new sites.


The applicable safety standards must be observed in order to be able to establish a technology in Germany. Our sites comply with the legally specified thresholds.


A mammoth task such as launching 5G cannot be done alone. That is why we are working closely with our partners and local municipalities. Together with research institutes, industry, and local municipalities, we also are trying out innovative application scenarios.

Vienna: The gigabit city

The Austrian national company Magenta Telekom is also driving forward network expansion at top speed: From 2018 to the end of 2021, it is investing around a billion euros to build and expand its mobile and fixed networks. Magenta Telekom supplies more than one million households in Vienna with gigabit speed. In terms of broadband internet, Vienna is one of the best-connected cities in the EU.


In the “All for one and one for all” issue, we take a look at the Sustainable Development Goals and the commitment Deutsche Telekom has made to achieve them. More information can be found here

= future

In expanding our network, we are also helping to achieve the Sustainable Development Goals of the United Nations (SDGs). Nationwide internet access is an important element in a sustainable infrastructure (SDG 9). It can help create new jobs, for instance, through more company start-ups (SDG 8). Network expansion also lays the foundation for many other positive effects, such as improved access to online educational offerings (SDG 4), more sustainable agriculture (SDG 15), and improved healthcare (SDG 3). The internet is also the basis for solutions that save energy and reduce CO2 (SDG 13) or improve life in cities (SDG 11).

Watching it live

We have connected more than 40 new households in Germany to our broadband fiber optic network since you started reading this text about ten minutes ago. How do we know that? We document almost in real time how our broadband expansion is progressing. You can see the total number of households now in a position to use a rate offering up to 100 Mbits or more per second as well as the current rollout statistics per hour, per day, and per week at When it comes to rapid network expansion, it’s quantity that matters the most. But, of course, the quality of the Deutsche Telekom network is also very important to us. For many years, we have regularly received awards for our network quality. In 2020, we were once again the overall winner in tests by “CHIP” and “connect” magazines.
