6G Summit in Dresden: Challenges for the Future

At the 6G Summit in Dresden, which took place on July 6, 2026, Prof. Gerhard Fettweis from the Technical University of Dresden presented the key challenges associated with the development of 6G by the year 2030. The event brought together experts from the telecommunications industry to discuss the future requirements for networks and hardware. Fettweis emphasized that the upcoming generations of mobile communication technology will require not only technological innovations but also new economic approaches.

A central theme of the discussion was the increasing uplink load caused by the growing interconnection of AI systems. These systems require significant bandwidth to communicate efficiently and exchange data. Fettweis pointed out that the infrastructure must be adjusted accordingly to meet the demands of these new technologies. The challenge lies in finding a balance between the required capacity and economic feasibility.

Frequency Usage and Lessons from 5G

Another important point raised by Fettweis was the necessity of a pragmatic frequency policy. Frequency usage plays a crucial role in the development of 6G, as the available frequencies must be utilized more efficiently to meet the rising demands. The experiences from the 5G millimeter-wave experiments are to serve as valuable lessons. These experiments have shown that there are both technical and regulatory challenges that need to be addressed.

The discussion about frequencies is particularly relevant, as the availability of spectrum is critical for mobile operators. Fettweis emphasized that close collaboration between regulatory authorities and the industry is necessary to optimize frequency allocation and not hinder the development of 6G. The challenges in this area are diverse and require innovative solutions.

Another aspect that was discussed at the summit was the integration of new technologies into existing infrastructures. The development of 6G will not only require new hardware but also a comprehensive overhaul of existing networks. Fettweis highlighted that the migration to 6G must occur gradually to ensure service continuity while also leveraging the new opportunities that 6G will offer.

The economic implications of 6G were also discussed in depth. Fettweis pointed out that investments in the new technology will be substantial and that companies must plan strategically to realize the benefits of 6G. Creating a stable economic environment is crucial to provide the necessary resources for research and development.

In conclusion, the importance of international collaboration was emphasized. The development of 6G is a global endeavor that requires cooperation between different countries and companies. Fettweis called for increased cooperation at the international level to tackle challenges together and to harness the benefits of 6G worldwide.

The 6G Summit in Dresden has thus provided important impulses for the future development of mobile communication technology and outlined the key challenges that must be addressed by 2030.
