The 6G-TWIN project was featured at the IEEE International Conference on Communications (ICC) 2025, held from 8–12 June at the Palais des congrès de Montréal. As one of the flagship events of the IEEE Communications Society, ICC 2025 brought together over 2,000 participants from academia, industry, and government to explore this year’s theme: “Communications Technologies 4Good.”

Chris Murphy, representing VIAVI Solutions and the 6G-TWIN project, delivered an invited talk in the industry program, contributing to the dialogue on how data and digital twin technologies are shaping the future of network optimisation and lifecycle management.

His presentation offered a historical perspective on the use of data to optimise communications networks, tracing developments from the GSM era to today’s increasingly complex and dynamic network environments. He argued that the growing complexity and ambition of 6G systems make the integration of digital twins essential at every stage of the network lifecycle—from design to real-time operations.

Chris highlighted how the 6G-TWIN project is spearheading the application of digital twin technology in two key 6G use cases:

  • Energy savings, through intelligent and predictive network management
  • Tele-operated driving, enabled by low-latency, high-reliability network emulation

He also introduced the work of 6G-DALI, a sister project that is designing a reference architecture for a 6G data space. This data space aims to federate research testbeds, promote data openness, and support distributed AI workflows and RLOps—enabled by the convergence of digital twin and data-centric architectures.

The session concluded with a lively discussion, with audience questions focusing on:

  • Latency tolerances between physical and virtual twin entities
  • Data acquisition and orchestration strategies
  • Deployment considerations for real-world use cases

This exchange underscored the growing recognition of digital twin technologies as a foundational pillar in the realisation of 6G goals, particularly when it comes to energy efficiency, automation, and trustworthy network intelligence.

Participation in IEEE ICC 2025 marked an important milestone for 6G-TWIN, reaffirming its role in the global research ecosystem and reinforcing its commitment to building a sustainable, intelligent, and data-driven communications future.
