Panel Discussion: The Spectrum above 100 GHz

Recorded Webinar: September 29, 2022


The Spectrum above 100 GHz: Reality Check by the mmWave Coalition


Wireless communications in the sub-terahertz and terahertz (THz) bands (or broadly speaking, from 100 GHz up to 10 THz) have been envisioned by both academia and industry as a key enabler of future sixth generation (6G) wireless networks. In the last five years, there has been major progress towards closing the so-called THz gap: testing, infrastructure and user technologies are quickly evolving; misconceptions relating to terahertz-wave propagation and interference have been cleared; and innovative signal processing, communication and networking protocols have been proposed; all while new question marks have risen, such as those concerning to the security of terahertz links or the coexistence between active and passive users of the spectrum above 100 GHz.

In this interactive panel, several members of the mmWave Coalition will provide an updated look at the opportunities and challenges in the spectrum above 100 GHz and jointly identify the next key milestones for the practical development and adoption of the field.

Michael J. Marcus, Marcus Spectrum Solutions
Topic: Spectrum Policy

Michael Marcus, Marcus Spectrum Solutions

Michael J. Marcus is a native of Boston and received S.B. and Sc.D. degrees in electrical engineering from MIT. Prior to joining the FCC in 1979, he worked at Bell Labs on the theory of telephone switching, served in the U.S. Air Force where he was involved in underground nuclear test detection research, and analyzed electronic warfare issues at the Institute for Defense Analyses. At FCC his work focused on proposing and developing policies for cutting edge radio technologies such as spread spectrum/CDMA and millimeter waves. Wi-Fi is one outcome of his early leadership. The total amount of spectrum he proposed for unlicensed use and directed the drafting of implementing rules was 8.234 GHz. He also participated in complex spectrum sharing policy formulation involving rulemakings such as ultrawideband and MVDDS. Awarded a Mike Mansfield Fellowship in 1997, he studied the Japanese language and spent a year at the FCC’s Japanese counterpart. He retired from FCC in March 2004 after servicing a senior technical advisor to the Spectrum Policy Task Force and codirecting the preparation of the FCC’s cognitive radio rulemaking. Immediately after retirement he lived in Paris France for 3 years, consulting for US and European clients. In 2006 he was appointed Special Advisor to Mrs. Viviane Reding, European Commissioner for Information Society & Media.He is now Director of Marcus Spectrum Solutions LLC, an independent consulting firm based in the Washington DC area focusing on wireless technology and policy. He is also Adjunct Professor of Electrical and Computer Engineering and Principal Research Scientist, Institute for the Wireless Internet of Things at Northeastern University. He was recognized as a Fellow of the IEEE “for leadership in the development of spectrum management policies”, received in 1994 IEEE-USA’s first Electrotechnology Transfer Award, and received in 2013 the IEEE ComSoc Award for Public Service in the Field of Telecommunications “For pioneering spectrum policy initiatives that created modern unlicensed spectrum bands for applications that have changed our world.
