Professor Harald Haas, a prominent figure in telecommunications, offers insights into the evolving landscape of 6G technology. As Van Eck Professor of Engineering at the University of Cambridge and Co-Director of the Federated Telecoms Hubs (FTH), Haas coordinates research across 35 UK universities.
Addressing the future of 6G, Professor Haas remarks that it is primarily a term used for marketing. However, continuous innovation in areas like AI, non-terrestrial networks, and core architecture development will shape its essence. Unlike the 5G transformation, future advancements will increasingly rely on software innovations.
A major aspect of 6G is expanding coverage to connect the unconnected. Satellite communications, drone communication, and aerial platform hubs are expected to play significant roles. For instance, by integrating satellite technology in the communication infrastructure, a seamless transition between generations can be achieved. With technologies first emerging in 5G, Haas emphasizes the importance of coverage and low-latency connections as autonomous systems, such as autonomous cars and drones, demand robust networks.
The role of IoT in networks, albeit gradually, stays integral. The evolution continues, driven by the need for intent-driven networks, moving beyond basic connectivity to intelligent infrastructure. This progression falls into the network’s adaptability, allowing data normalization, ensuring trustworthy information, and training AI models for consistent network behavior.
Steering the beams in multi-antenna systems highlights interference management challenges. Spectrum-sharing is more common, with the UK leading in this area. Non-terrestrial networks (NTNs) blend into the landscape. AI aids in predicting traffic and optimizing flows for low latency worldwide, becoming crucial in future networks.
6G discussions revolve around making existing systems more dependable and commercially feasible. Haas emphasizes focusing on real-world applications over flashy technology. Autonomous systems typify the merging of technology with practicality, with human-like functions replicated through a blend of communication, computing, and control.
For instance, Professor Haas founded pureLiFi, introducing a product named Lightbridge that transmits 5G signals indoors using light channels. This innovation can double or triple indoor capacity. The trials indicate significant reliability improvements and signal enhancements.
In the evolving domain of telecommunications, networks need to have enhanced defence capabilities. As vulnerabilities in cybersecurity rise, networks must adapt to ensure safety and efficiency. The demand for innovation intensifies in contested environments, suggesting dual-use technologies could emerge even in defence.
Overall, Professor Harald Haas provides a broad perspective on the dynamic shift towards 6G, emphasizing coverage, connectivity, and the seamless blend of AI and networks. His insights suggest that adaptability and purpose-driven technology define the future of telecommunications.
