Forum Numerica - Sumit Roy: "Beyond 5G Networks: Strategic Roadmap and R&D Prospects"

IEEE Future Networks Distinguished Lecture


During 2020-2022, the speaker served as Program Lead for Innovate Beyond 5G, DoD OUSD Office of Research & Engineering, managing an annual portfolio for research and prototyping in support of significant investment by DoD/USG with respect to adopting 5G for the Enterprise and Innovating Beyond (i. e. pushing technology boundaries beyond current 5G implementation). Accordingly, the talk will be divided into 2 components:

  • An initial brief Overview of DoD 5G-to-xG R&D strategy (towards enabling future Integrated Tactical Network concepts based on emerging 5G New Radio (NR) network features such as direct Device-2-Device (sidelink) modes, non-terrestrial networking, impact of RAN disaggregation and virtualization, dynamic spectrum sharing and management between 5G/B5G and DoD/Federal networks (current emphasis on 3.1-3.45 GHz)

followed by a deeper technical dive into

  • Performance aspects of Sidelink Mode-2 enabled ad-hoc networking (such as Cellular V2X) and current status of Integrated Access & Backhaul (IAB), highlighting feature gaps and R&D opportunities.

Finally the talk will conclude with distilling the impacts of the above as potential vectors for 5G+/6G standardization and the importance of creating more diverse national pathways for participation in global standards evolution aiming for national leadership in 6G.

About the speaker

Sumit Roy (Fellow, IEEE 2007) received the B. Tech. degree from the Indian Institute of Technology (Kanpur) in 1983, and the M. S. and Ph. D. degrees from the University of California (Santa Barbara), all in Electrical & Comp. Engineering (1985 and 1988 respectively), as well as an M. A. in Statistics and Applied Probability (1988). His previous academic appointments were at the Moore School of Electrical Engineering, University of Pennsylvania, and at the University of Texas, San Antonio. His research interests and technology expertise spans analysis/design and prototyping of wireless communication systems/networks, with an emphasis on various technologies: 5G wireless LANs (802.11ax), 5G New Radio and emerging 5G/beyond 5G standards for vehicular (terrestrial and airborne) networks, multi-standard inter-networking/coexistence and dynamic spectrum access solutions for spectrum sharing. He was elevated to IEEE Fellow by Communications Society for ``contributions to multi-user communications theory and cross-layer design of wireless networking standards” and held the ECE-CoE Integrated Systems Term Professorship (2014-19) at Univ. of Washington in recognition of his international reputation in the area.

He spent 2001-03 on academic leave at Intel Wireless Technology Lab as a Senior Researcher engaged in systems architecture definition and IEEE standards contributions for ultra-wideband systems (Wireless PANs) and next generation high-speed (pre-802.11n) wireless LANs. He served as Science Foundation of Ireland Isaac Walton Fellow during a sabbatical at University College, Dublin (Jan-Jun 2008) and was the recipient of a Royal Acad. Engineering (UK) Distinguished Visiting Fellowship during summer 2011. During 2014-15, he spent a sabbatical year at Microsoft Research, Bangalore, India, as Erskine Fellow at University of Canterbury, New Zealand and as Short Term Visiting Foreign Expert at Shanghai JiaoTung University. His research has been consistently funded by various US agencies and industrial organizations leading to 10 awarded US patents and his work on Radar-WiFi Spectrum Sharing published in 2016 was recognized by IEEE Trans. Aersosp. Elect. Systems with Barry Carlton (Best Paper) Award. He also currently represents US on the NATO SET-302 Technical Working Group on `Cognitive Radar’.

He continues to be professionally active in IEEE Communications Society (ComSoc) - notably IEEE Future Networks Initiative ( for which he currently serves as Distinguished Lecturer. He has served as Associate Editor for all the major ComSoc publications (IEEE Trans. Communications, IEEE J. Sel. Areas of Communications, IEEE Trans. on Wireless Communications, IEEE Trans. Mobile Computing) at various times and was previously selected for two stints as IEEE ComSoc Distinguished Lecturer (2013-2015, 2017-18). He was also elected to Executive Comm. Member for the National Spectrum Consortium ( Between Sep. 2020-22, he served as Program Lead for Innovate Beyond 5G program within US DoD Office of Under Secy. R&E’s 5G-to-xG initiative .
