Slides and Recordings: 6G: Technology Enablers for Spectrum & Energy Efficient Wireless Access

On Wednesday 26 May the Minister for Digital Infrastructure, Matt Warman MP, opened the first in a series of University-run workshops to showcase the current research projects having the best potential to address 6G wireless research priorities. 

The University of Bristol led workshop, supported by DCMS and UK SPF, focused on physical layer hardware technologies and architectures as well as new materials to enhance both spectrum and energy efficiency of next generation networks.

The UK Spectrum Policy Forum (SPF) and DCMS are supporting a series of University-run workshops to showcase the current research projects having the best potential to address 6G wireless research priorities. Bristol, Surrey and Strathclyde have been selected to run the workshops but the intention is for these workshops to be a platform for all UK universities having relevant wireless research. Each hosting University has been entrusted by the SPF and DCMS to identify outstanding research projects from other Universities to showcase at their workshops. The output from this series of workshops will be a White Paper for the UK SPF to present to government that validates the research projects as relevant to UK 6G research priorities, identifies gaps, suggests opportunities for collaboration, looks at the adequacy of research funding streams and flag potential implications for 6G spectrum policy.
