Network expansion

Here is a selection of material topics from the 2018 CR-Report. More information can be found in the chapters Customers & products and Climate & environment.

Continuing expansion of the fiber-optic network

Deutsche Telekom operates the largest fiber-optic network in Europe, covering a length of 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 online ticker to report on our progress.

To reach this goal, we are using FTTC img (fiber to the curb) technology and are expanding FTTH img (fiber to the home) as well. In the scope of the FTTC expansion, fiber optics are laid to the gray street cabinets on the curb. From there we can supply our customers with large bandwidths via existing infrastructure by means of super vectoring. With FTTH, the fiber-optic cables are taken right into the customer’s home.

  DSL img 16000 FTTC with super vectoring FTTH
Download up to 16 Mbit/s up to 250 Mbit/s up to 1,000 Mbit/s
Upload up to 2.4 Mbit/s up to 40 Mbit/s up to 500 Mbit/s

Super vectoring compensates for electromagnetic interference that arises between the copper lines on the way to the households. The technology allows for faster data transmission with speeds of up to 250 Mbit/s img. The technology for this is installed in the cable distribution box.

Continuing expansion of the LTE mobile network

The expansion of LTE mobile technology in the Deutsche Telekom network ensures more extensive reach and higher speeds. LTE network coverage had reached about 98 percent of the population in Germany and 97 percent in Europe by the end of 2018, putting our European national companies in line with their target coverage.

Bestes Netz

CHIP (issue 1/2019)

We came out on top in CHIP’s mobile network test and were voted best network.

Connect mobile network test (issue 1/2019)

We were also the overall winner of the 2019 Connect mobile network test, with a rating of “very good”. The testing examined the voice and connection quality during phone calls as well as data communication via mobile internet. The measurements were taken at various locations, such as cities and small towns as well as on trains.

New communications standard: preparations for 5G in full swing

The current LTE communications standard is the fourth generation standard (4G). LTE is continually developing and can so far fully meet the requirements of consumers for ever greater bandwidth. The new 5G communications standard will not only offer significantly improved network capacity and higher speeds, but also lower latencies, greater reliability and security, and improved network flexibility for customized solutions. As a result, 5G will enable a host of applications in industry and the logistics sector that are not yet even conceivable by today’s standards.

Eight-point program for 5G development
In October 2018, Deutsche Telekom presented an eight-point program for developing a 5G network infrastructure. The goal: In Germany, we plan to cover 99 percent of the population and 90 percent of the country with 5G by 2025.

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 S-RAN (Single Radio Access Network) modernization currently underway, and new services such as LTE 900 or 4x4 MIMO, the more than 27,000 mobile sites in Germany will be ready, if they are not already, for the new standard and able to map initial 5G applications.

Step one: 5G test field in Berlin
Since May 2018, the first 5G antennas in Europe to fully support the new communications standard have been operating under real conditions in Deutsche Telekom’s network in downtown Berlin. The antennas are part of a 5G test field in the heart of the capital.

They are based on the future 5G standard for the non-standalone version of mobile communications component 5G New Radio (5G NR) - in other words, 5G networks based on 4G core network infrastructures. The standard was approved by the international standardization body 3GPP (3rd Generation Partnership Project) in December 2017. 5G NR is ideally suited for 5G applications using the medium frequency band belowGHz, which supports a good mixture of key characteristics, including broad coverage, high multigigabit range data throughput and low latencies in the order of just a few milliseconds. The antennas in Berlin are currently using the 3.7 GHz range under a test license. The licenses and frequencies issued by Germany’s Federal Network Agency will provide the basis for the 5G spectrum system and related planning in Germany in 2019.

Testing applications
To allow innovative developers to test their ideas for 5G in Berlin under real-world conditions, Deutsche Telekom has launched the 5G prototype program together with its start-up incubator hubraum.

In a world first, the Hamburg Port Authority, Deutsche Telekom, and Nokia are testing new aspects of the 5G standard using various applications in real-world industrial conditions at the Port of Hamburg in Germany. The around 8,000-hectare site has been a test field for testing the industrial capability of the future technology since January 2018: the transmission of movement and environmental data in real time, reliable traffic light controls, and virtual reality applications. The field test allows us to develop new and innovative solutions for industry, and serves as a basis for defining other aspects of the 5G standard.

The field test was also made possible by a new 5G installation on the Hamburg television tower. It was installed as part of the EU research project “5G-MoNArch”. The aim of the project is to test concepts for the 5G mobile architecture in practice.
