Our approach for infrastructural expansion

Our contribution to the SDGs

As the biggest investor in Germany’s network, our network expansion efforts are geared toward three key aspects – growth, efficiency, and quality.
We will continue to expand our networks, increase the efficiency of our systems, and further strengthen our role as a leader in network quality.

Germany’s mobile network is being expanded under the terms and conditions resulting from the 2019 spectrum auction held by the German Federal Network Agency. Our initial target is to ensure nearly all households in the country (99 percent) have LTE coverage by the end of 2020. We will also continuously improve the coverage of traffic routes with bandwidths of 100 Mbit/s img or 50 Mbit/s. At the same time, we are kick-starting a new generation of mobile communications across the whole of Germany. By the end of 2025, we will provide 5G coverage to 99 percent of the population.

In the fixed network, we have almost completed our FTTC img (fiber to the curb) build-out and are now bringing fiber-optic connections into customers’ homes through our FTTH img (fiber to the home) expansion. Our initial focus is on expanding into business parks and rural areas (with state funding) and establishing collaborations.

Over the coming years, we will successively extend our FTTH expansion to reach up to an additionalmillion households each year.

Progress in network expansion KPI

Part of our network strategy is to also systematically build out our mobile networks with 4G/LTE technology to increase transmission rates in all national companies. Thanks to investments in our 4G/LTE network, our customers enjoy better network coverage with fast mobile broadband. In 2019, for example, we were already providing approximately 98.1 percent of the population in Germany with LTE coverage and 98 percent in Europe. This puts us right on schedule to reach our goal of 99 percent network coverage by 2020.
Furthermore, around 31 million households in Germany can already order a rate with up to 100 Mbit/s img on our fixed network. This figure keeps growing daily, as can be followed in our online expansion tracker.

Updating and stabilizing the network architecture

We are making our networks faster and more efficient. To do this, we are deactivating all analog public switched telephone network (PSTN) platforms that we no longer need and switching our entire telephone network to IP-based lines. By the end of 2019, around 99 percent of lines had already been switched to IP img technology.

Irrespective of the expansion and renewal of our infrastructure, we aim to operate our networks in the most stable and failure-free manner possible. Major events such as festivals and summits place the network under particular strain. We make sure, however, that voice calls and data are still transmitted in the quality our customers have come to expect by temporarily setting up extra mobile masts or laying fiber-optic cables. In the event of natural disasters such as floods, our Disaster Recovery Management team ensures those affected can quickly start communicating again.

5G expansion

In October 2018, Deutsche Telekom presented an eight-point program for developing a 5G network infrastructure. The aim in Germany is to cover 99 percent of the population and 90 percent of the country with 5G by 2025.


  • By the end of 2019, Deutsche Telekom’s 5G network was already operational in eight German cities – Berlin, Bonn, Darmstadt, Frankfurt, Hamburg, Cologne, Leipzig, and Munich. By the start of 2020, Deutsche Telekom had already built 450 5G antennae, with this figure set to reach four digits as the year progresses. We aim to operate over 1,500 5G antennae, including in all 16 German state capitals, by the end of 2020.
  • When it comes to the transition from LTE to 5G, the further expansion of LTE/LTE Advanced contributes to the future 5G infrastructure, because LTE is the basis for 5G and will remain an integral part of it. There will be no standalone version of 5G at the start. Instead, in line with the standardization and development plans, parts of the implementation of 5G will initially be mapped in LTE. Implementing 5G is an evolution: thanks to a fiber-optic connection, the SRAN (Single Radio Access Network) modernization which is currently underway, and new services such as LTE 900 or 4xMIMO, the 30,000 or so mobile sites in Germany will soon be ready, if they are not already, for the new standard and will be able to map initial 5G applications.

Continuing expansion of the fiber-optic network

Deutsche Telekom operates the largest fiber-optic network in Europe, covering a length of well over 500,000 kilometers in Germany alone. We are further expanding our fiber-optic network to keep pace with demand for higher bandwidths in the network. We use our expansion tracker for Germany to report on our progress.

To reach this goal, we are using FTTC img (fiber to the curb) technology with super vectoring and are expanding FTTH img (fiber to the home) as well.
