6G Network Development Overview: From 5G Lessons to the Future of Communication Revolution

With 5G networks now rolling out globally, the telecommunications industry is focusing on the next major leap—6G. In March 2025, IPLOOK attended the 3GPP 6G seminar with many experts to discuss the challenges and lessons learned from 5G deployment and provide guidance for the development of 6G. While 6G continues the evolution of 5G, it will also introduce new technologies and societal changes, with profound impacts on communication and industry.

Lessons Learned from 5G and 6G Directions
The transition from 5G Non-Standalone (NSA) to Standalone (SA) architectures has been a significant challenge, with deployment becoming complex due to various configuration options. The slow adoption of advanced features like network slicing has hindered network flexibility. Additionally, inefficiencies in protocols have limited performance. These lessons are shaping the design principles for 6G: simplifying network architecture, ensuring modularity, prioritizing efficiency, and preparing for the future with robust security.

Technological Innovations for 6G
6G will push the boundaries of wireless communication by exploring the 0.1-10 THz spectrum, offering far greater bandwidth and faster speeds. The dynamic sharing of spectrum and collaboration between satellites, high-altitude platforms, and ground-based networks will enable global, seamless coverage. Furthermore, AI will play a central role in 6G, enabling network self-optimization, predictive maintenance, and resource management.

Applications and Commercial Value
6G will unlock new applications in areas like immersive collaboration, precision healthcare, and industrial automation. Holographic communication will enable remote collaboration in high definition, and 6G will transform healthcare with real-time monitoring and remote surgeries. The business models for 6G will introduce network capabilities as services, creating new revenue opportunities, while industry-specific solutions, like dedicated network slices, will meet the needs of vertical markets.

Sustainable Development
6G is also focused on sustainable development. With innovations in energy efficiency and material recycling, 6G will reduce energy consumption while providing global connectivity. It will help bridge the digital divide, fostering inclusive connectivity for underserved regions.

Future Outlook
6G is expected to complete key technology verifications by 2027, enter standardization between 2027-2029, and launch its first commercial deployments around 2030. By the mid-2030s, 6G will be globally implemented, transforming society.
IPLOOK is committed to advancing 6G technologies, collaborating with global partners to provide sustainable and intelligent solutions for the future.
