  • Aarno Pärssinen (Univ. of Oulu, FI)

Motivation and Background

Upper mmW region from 100GHz up to THz range is getting a lot of interest in 6G radio research for communications and sensing. However, physical boundaries in technologies from semiconductors to packaging will force us to rethink how we implement radios capable of extremely high sensing and imaging precision and data rates up to and beyond 100Gbps in communications. Feasibility of enabling technologies needs to be considered and confirmed before standardization taking cost and power consumption into account.
Silicon-based semiconductor technologies have been dominating and facilitating the industry for more than 30 years miniaturizing radio frequency (RF) hardware and improving digital processing capabilities such that their enablement to reduce size, power consumption and add flexibility have been considered self-evident. Already lower mmW bands and data rates that 5G can support have shown the first signs that future might not be as straightforward as one would wish. Early research is already showing that in 6G challenges will not get any easier, vice versa.
This panel with top experts from industry and academia will discuss the challenges and opportunities to achieve the goals, and highlight issues that communication industry should consider and foster in advance to facilitate standardization. It is evident that hardware and physics-based boundaries require more attention than in previous cellular generations. Co-design from systems and algorithms to radio RF and computing hardware are core elements for success.


  1. What are the biggest disruptions and challenges in technologies as we are moving towards THz region and what use cases they will potentially enable?
  2. What are the key new enabling technologies that we need compared to generations up to 5G when moving up in data rates and thus carrier frequencies?
  3. Does it make sense to combine radio communications, localization, sensing, imaging and spectroscopy and which of them? Or should they be seen as stand-alone functions in future devices?
  4. Do you see any role or opportunities in machine learning or artificial intelligence that would facilitate RF/digital hardware design and not just require more computational resources?
  5. What are the key items from your perspective requiring early-phase co-design between HW and communications/sensing systems?
