Deutsche Telekom is demonstrating the future of mobile communication by deploying high-speed 5G antennas across real-world locations in Berlin. These installations deliver very high throughput and extremely low latency, offering a practical preview of how 5G will reshape connectivity.
Claudia Nemat, Member of the Management Board responsible for Technology & Innovation at Deutsche Telekom, emphasized the importance of real-world testing: “We are showing 5G live here, in the middle of Berlin, not just in a lab. This is a critical step toward the planned global rollout of 5G in 2020. As devices and systems become increasingly interconnected, customers will need networks that are high-performing, reliable and secure. Industry stands to gain particularly from 5G as a powerful enabler for many new applications. We are ready for 5G.”
To highlight the network’s capabilities, Deutsche Telekom showcased early application concepts that take advantage of 5G’s strengths. Augmented reality (AR) and virtual reality (VR) demos illustrated how super-high data rates and near real-time responsiveness can enhance immersive experiences, enabling smoother visuals and more reactive interactions.
At the heart of the next generation of mobile communications is 5G New Radio (5G NR), the new air interface designed to operate alongside the ongoing evolution of 4G/LTE. This combined approach will shape future networks, ensuring continuity while unlocking new performance levels. One of the key technologies enabling improved capacity and throughput in 5G NR is advanced antenna design—particularly Massive MIMO (multiple input/multiple output). By increasing the number of antenna elements at both base stations and user devices, Massive MIMO uses the available frequency spectrum far more efficiently, raising capacity and delivering higher data rates to users.
Recent research also points to innovative antenna concepts that could further relieve spectrum congestion and strengthen wireless signals. For example, researchers at the ElectroScience Laboratory (ESL) at Ohio State University have proposed a floating antenna architecture featuring suspended, high-gain millimetre-wave arrays. Built using a combination of 3D printing and MEMS (Micro-Electro-Mechanical Systems), such designs aim to improve signal performance and make more effective use of crowded electromagnetic bands.
These advances—real-world 5G deployments, enhanced air interfaces like 5G NR, Massive MIMO, and novel antenna structures—together form a trajectory toward networks capable of supporting a vast range of new services. From industrial automation and remote-controlled machinery to enriched consumer AR/VR experiences and beyond, the low latency and high throughput of 5G are positioned to enable applications that were previously impractical over wireless links.
By testing 5G today in an urban environment like Berlin, Deutsche Telekom is validating network behavior under real conditions, gathering insights that will inform broader rollouts and optimizations. Practical demonstrations reveal not only peak performance figures but also how 5G behaves amid the complexities of city life—buildings, moving users, and varied device densities.
As networks evolve, operators and equipment makers will continue refining radio interfaces, antenna technology and deployment methods to balance capacity, coverage and reliability. Together with research into new antenna forms and manufacturing techniques, these efforts aim to ensure that the transition to 5G delivers tangible benefits for consumers, businesses and public services in the years ahead.
