Since the development of the 4G LTE standards around 2010, the research communities both in academia and industry have been brainstorming to predict the use cases and scenarios of 2020s, to determine the corresponding technical requirements, and to develop the enabling technologies, protocols, and network architectures towards the next-generation (5G) wireless standardization. This exploratory phase is winding down as the 5G standards are currently being developed with a scheduled completion date of late-2019; the 5G wireless networks are expected to be deployed globally throughout 2020s. As such, it is time to reinitiate a similar brainstorming endeavour followed by the technical groundwork towards the subsequent generation (6G) wireless networks of 2030s.
One reasonable starting point in this new 6G discussion is to reflect on the possible shortcomings of the 5G networks to-be-deployed. 5G promises to provide connectivity for a broad range of use-cases in a variety of vertical industries; after all, this rich set of scenarios is indeed what distinguishes 5G from the previous four generations. Many of the envisioned 5G use-cases require challenging target values for one or more of the key QoS elements, such as high rate, high reliability, low latency, and high energy efficiency; we refer to the presence of such demanding links as the super-connectivity.
However, the very fundamental principles of digital and wireless communications reveal that the provision of ubiquitous super-connectivity in the global scale – i.e., beyond indoors, dense downtown or campus-type areas – is infeasible with the legacy terrestrial network architecture as this would require prohibitively expensive gross over-provisioning. The problem will only exacerbate with even more demanding 6G use-cases such as UAVs requiring connectivity (ex: delivery drones), thus the 3D super-connectivity.
In this lecture, we will present a 5-layer vertical architecture composed of fully integrated terrestrial and non-terrestrial layers for 6G networks of 2030s:
• Terrestrial HetNets with macro-, micro-, and pico-BSs
• Flying-BSs (aerial-/UAV-/drone-BSs); altitude: up to several 100 m
• High Altitude Platforms (HAPs) (floating-BSs); altitude: 20 km
• Very Low Earth Orbit (VLEO) satellites; altitude: 200-1,000 km
• Geostationary Orbit (GEO) satellites; altitude: 35,786 km
In the absence of a clear technology roadmap for the 2030s, the lecture has, to a certain extent, an exploratory view point to stimulate further thinking and creativity. We are certainly at the dawn of a new era in wireless research and innovation; the next twenty years will be very interesting.

All researchers and students are welcome.
Halim Yanikomeroglu (F’17) was born in Giresun, Turkey, in 1968. He received the B.Sc. degree in electrical and electronics engineering from the Middle East Technical University, Ankara, Turkey, in 1990, and the M.A.Sc. degree in electrical engineering (now ECE) and the Ph.D. degree in electrical and computer engineering from the University of Toronto, Canada, in 1992 and 1998, respectively.
During 1993–1994, he was with the R&D Group of Marconi Kominikasyon A.S., Ankara, Turkey. Since 1998 he has been with the Department of Systems and Computer Engineering at Carleton University, Ottawa, Canada, where he is now a Full Professor. His research interests cover many aspects of wireless technologies with a special emphasis on cellular networks. Dr. Yanikomeroglu has supervised 18 PhD and 28 MASc theses (all completed); several of his PhD students received various medals. He has coauthored 350+ peer-reviewed research papers including 115 in the IEEE journals; these publications have received around 10,500 citations. He has been one of the most frequent tutorial presenters in the leading international IEEE conferences (29 times). He has had extensive collaboration with large-scale (such as Huawei, Samsung, Blackberry, Nortel), medium-scale (such as Telus, DragonWave), and small-scale (such as Mapsted) companies as well as the government labs (such as Communications Research Centre of Canada). During 2012-2016, he led Canada’s largest academic-industrial collaborative research project on pre-standards 5G wireless research, sponsored by the Ontario Research Fund – Research Excellence (ORF–RE) program. Dr. Yanikomeroglu’s collaborative research resulted in 24 granted patents (plus about 15 applied).
Dr. Yanikomeroglu is a Fellow of the IEEE with the citation “for contributions to wireless access architectures in cellular networks”. He is a Distinguished Lecturer for the IEEE Communications Society and a Distinguished Speaker for the IEEE Vehicular Technology Society. He has been involved in the organization of the IEEE Wireless Communications and Networking Conference (WCNC) from its inception in 1998 in various capacities including serving as a Steering Committee member for a decade and the Technical Program Chair/Co-Chair of WCNC 2004 (Atlanta), WCNC 2008 (Las Vegas), and WCNC 2014 (Istanbul). He was the General Co-Chair of the IEEE 72nd Vehicular Technology Conference (VTC 2010-Fall) held in Ottawa, and the General Chair of the IEEE 86th Vehicular Technology Conference (VTC 2017-Fall) held in Toronto. He has served in the editorial boards of the IEEE Transactions on Communications, IEEE Transactions on Wireless Communications, and IEEE Communications Surveys & Tutorials. He was the Chair of one of the largest technical committees in IEEE, Technical Committee on Personal Communications (now called Wireless Communications Technical Committee and has 1,700+ members).
Dr. Yanikomeroglu is a recipient of the IEEE Ottawa Section Outstanding Educator Award in 2014, Carleton University Faculty Graduate Mentoring Award in 2010, the Carleton University Graduate Students Association Excellence Award in Graduate Teaching in 2010, and the Carleton University Research Achievement Award in 2009 and 2018. Dr. Yanikomeroglu spent the 2011–2012 academic year at TOBB U. of Economics and Technology, Ankara, Turkey, as a Visiting Professor. He is a registered Professional Engineer in the province of Ontario, Canada.
