O2 Telefónica creates mobile freedom with 5G
O2 Telefónica is pushing ahead with the expansion of its 5G network in leaps and bounds. With 5G, the company is democratizing high-tech and making the new mobile communications standard available to the mass market. The O2 5G network was launched on October 3, 2020 in the five largest German cities of Berlin, Hamburg, Munich, Cologne and Frankfurt. Since then, the company fired up the 5G expansion turbo: In the meantime, the O2 5G network already covers about 97 percent of the German population (as of November 2024). O2 Telefónica brings 5G to more and more cities and especially rural regions. In our 5G network rollout, we are focusing on the frequencies at 3.6 GHz acquired by auction in 2019, which offer customers highest 5G speeds and capacities. This will enable us to offer our customers particularly powerful 5G for the use of their digital applications. In addition, we are also rolling out our 5G network on long-range frequencies (700 MHz; 1800 MHz).
By the end of 2025, we will offer a nationwide 5G network. In order to provide our consumers with nationwide coverage much faster than in the past, we will use a very broad spectrum of technologies. At the same time, we are also continuing to improve our 4G network, already covers around 100 percent of the German population. As a result, more and more O2 customers will be able to enjoy a significantly faster and more powerful O2 network.
Our O2 customers benefit from 5G
"We provide our approximately 45 million consumers and business customers with an increasingly powerful O2 mobile network for their digital applications. With our fast-growing 5G network, we will also further accelerate digitization for consumers and businesses in Germany." Markus Haas, CEO Telefónica Deutschland

Our 5G Projects
Our focus is not on technology, but on the actual benefit for customers and industry. As a digital champion, we are ensuring that Germany is transformed into a fully networked and mobile society. Telefónica Deutschland / O2 is continuously driving forward the 5G expansion for O2 private and business customers as well as for industry.
Development 5G Technology
5G enables flexible production and logistics processes in industry 4.0. Since October 2020, private customers in the O2 network have also benefited from the new 5G standard. In the coming years, numerous new applications will be developed on the basis of 5G. Telefónica Deutschland / O2 has been testing modern 5G applications since 2016. Data rates of up to 1.7 Gbit/s have already been achieved.
5G in industry and production
Telefónica Deutschland / O2 has opened the 5G era for German industry. Together with the equipment supplier Ericsson for Mercedes-Benz Cars in Sindelfingen ("Factory 56"), the company has built the first 5G mobile network for automobile production. An independent campus network ensures the intelligent networking of the car manufacturer's machines and systems.
5G for networked driving
Telefónica Deutschland / O2 can also use 5G for real-time communication in road traffic. As a project partner in the "5G Connected Mobility" project, the company is participating in the A9 motorway test of 5G for networked driving. Together with SEAT, Telefónica demonstrated in Spain the communication between vehicles, pedestrians and objects (V2X) as well as 5G vehicle entertainment.
5G as DSL replacement
DSL via 5G radio - also known as Fixed Wireless Access - is an exciting 5G application field. Telefónica Germany / O2 has successfully tested new fixed wireless connections based on 5G together with Samsung in Hamburg. Customers only need a router and a receiver - there is no faster way to connect to broadband.
5G for broadcasting
Customers want to access video content at any time "on demand" and stream it via their end device. But how would broadcasting over 5G work? Telefónica Germany / O2 has done pioneering work in this area: At the transmitter site in Wendelstein near Rosenheim, a test field for broadcasting over 5G in the frequency range around 700 MHz is operated in the "5G Today" project. The partners in the project - which is managed by the Institut für Rundfunktechnik - include Telefónica Deutschland / O2, Kathrein, Rohde & Schwarz and Bayerischer Rundfunk.
Our 5G areas of application
Mobile Broadband
With 5G, the O2 network can once again achieve significantly higher data transmission rates, especially in conjunction with LTE (4G), which will continue to form the backbone of the network infrastructure. With 5G, customers download large files in seconds. With 5G, they have access to higher usage speeds as well as another high-speed network in addition to LTE. This is where the technical term for enhanced mobile broadband (eMBB) comes from.
In addition to standard data services, 5G allows applications such as virtual reality (VR) and augmented reality (AR) to develop their full potential in private and commercial use. It makes no difference whether customers use mobile devices such as smartphones and tablets or will rely on "DSL via radio" - i.e. Fixed Wireless Access - in the future. Telefónica Deutschland has already successfully demonstrated how customers with Fixed Wireless Access will be able to use a high-performance fixed network alternative via the 5G mobile network (mmWave) in the future.

Real-time applications
5G enables ultra-fast latencies of less than 1 millisecond in conjunction with edge computing. For the first time, applications can be implemented in real time. Due to highest reliability and extremely short reaction times, 5G is an important support for highly sensitive, automated production processes as well as for networked driving.
Vehicles, road users and road infrastructure such as traffic lights or bicycles communicate with each other in real time (V2X communication), which can prevent accidents and save lives. In addition, Telefónica Deutschland can bring the "Smart Factory" to life with 5G and drive forward the digitalization of companies. It makes no difference whether companies want to use the nationwide network infrastructure, a separately secured network slice or even a stand-alone campus solution.
