Our 5G Network
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 around 96 percent of the German population (as of July 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.
5G Campus at BASECAMP Berlin
Telefónica Deutschland / O2 opened the capital's first 5G campus network in March 2020 at its BASECAMP in Berlin-Mitte. The telecommunications provider is the leader in Germany in local 5G solutions. Thanks to the 5G indoor campus solution, BASECAMP will become a "5G campus". The BASECAMP enables all interested politicians, business representatives, founders and consumers to try out and get to know the 5G mobile phone technology.
5G takes O2 business customers to a new level
With O2 Business, Telefónica Deutschland / O2 offers a unique package of mobile and fixed network services as well as excellent service for its business customers. With O2 Business, small and medium-sized companies as well as larger corporations benefit from the advantages of the new 5G mobile phone standard.
In addition, with Narrowband IoT and LTE-M, O2 offers its business customers two further standards for their digital business and the intelligent networking of devices, e.g. for smart metering. Through network slicing, 5G opens up further opportunities for cooperation between Telefónica Deutschland / O2 and its business customers.
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.
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.

Internet of Things (Massive IoT)
With modern IoT solutions, Telefónica Deutschland enables automated data transfer between objects and machines. The company offers customers the two network standards Narrowband IoT and LTE-M. With 5G, intelligent networking via the Internet of Things is once again experiencing a much wider range of applications. This is referred to as "Massive IoT" - the networking of millions of devices with each other.
With 5G, not only private end devices such as Smartwatches and Fitness Trackers are networked. Cities are becoming "smart cities", where networked devices help us in our everyday lives. Smart metering supports the automatic reading of electricity, gas and water consumption, for example.
In addition, entire branches of industry such as logistics are benefiting from networking their fleets and vehicles. For individual fields of application, Telefónica Germany / O2 can even provide its customers with a separate network infrastructure by means of Network Slicing, thus reducing the complexity of the network.
