Wireless Access Architecture: The Next 20+ Years
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 use-cases of 2030s such as UAVs requiring connectivity (ex: delivery drones), thus the 3D super-connectivity.
The roots of today’s wireless access architecture (the terrestrial 4G & 5G cellular network) go back to 1940s. The access architecture has evolved substantially over the decades. However, rapid developments in a number of domains outside telecommunications, including those in aerospace and satellite industries as well as in artificial intelligence, will likely result in a disruptive transformation in the wireless access architecture in the next 20+ years.
In this talk, an ultra-agile, dynamic, distributed, and partly-autonomous vertical heterogeneous network (VHetNet) architecture with very low earth orbit satellites (VLEOs), high-altitude platform station (HAPS) systems, and UAV-BSs (UxNB in 3GPP terminology) for almost-ubiquitous super-connectivity will be presented.
In the envisioned VHetNet architecture, the HAPS systems constitute arguably the most promising tier. For more information on HAPS systems, please refer to the below papers under review:

His extensive collaboration with industry on 4G & 5G wireless technologies resulted in 37 granted patents. During 2012-2016, he led one of the largest academic-industrial collaborative research programs on pre-standards 5G wireless. In Summer 2019, he started a new large-scale project on the 6G wireless network architecture. He supervised 26 PhD students (all completed with theses). He is a Fellow of IEEE, EIC (Engineering Institute of Canada), and CAE (Canadian Academy of Engineering), and a Distinguished Speaker for both IEEE Communications Society and IEEE Vehicular Technology Society. He served as the General Chair and Technical Program Chair of several major IEEE conferences; he also served in the Editorial Boards of several IEEE periodicals. He served as the Chair of IEEE Technical Committee on Personal Communications, and he is currently chairing the Steering Committee of IEEE’s flagship Wireless Communications and Networking Conference (WCNC). Dr. Yanikomeroglu received several awards for his research, teaching, and service, including the IEEE Wireless Communications Technical Committee Recognition Award in 2018 and the IEEE Vehicular Technology Society Stuart Meyer Memorial Award in 2020.
There are three interrelated concepts of development of telecommunication networks today: 5G, 6G and Network 2030. The creation of fifth-generation telecommunication networks is the first step towards a fundamental modernization of telecommunication networks towards the emergence of ultra-highly reliable networks with ultra-low delays.
Ultra low delays due to fundamental restrictions on the speed of propagation of light lead to decentralization of the network and create preconditions for the decentralization of the economy. If the delay is limited to a value of, for example, 1ms, taking into account the application of this value to the two-way delay and assuming the use of modern high-bandwidth systems as transmission systems, the network range for providing, for example, Tactile Internet services is limited to about 50 km. This means that the operator's resources (for example, data centers) in communication networks with ultra low latency should be located, if possible, in the center of a circle with a radius of 50 km. This is the decentralization of the network. The Russian Federation will need at least 6-8 thousand data processing centers installed, including in district centers. Naturally, along with it, the economy will decentralize by reducing the digital divide between different territories, which is one of the main tasks of building the state's digital economy. This process will already begin with the introduction of sixth generation telecommunication networks.
One of the most important applications for 2030 networks is the widespread use and distribution of avatars and human holographic copies to reproduce and perform the actions of the person who controls them (telepresence). These networks should effectively reduce the digital device between territories, as well as effectively resist pandemic-like phenomena through telepresence services.

Virtual reality and teleportation, to telepresence, augmented reality, and remotely‑controlled robotics are future applications that are bound to achieve unprecedented development for society, economics and culture and to revolutionize the way we live, learn, work and play. Unfortunately, today’s Internet is simply not able to provide the stringent performance requirements needed by such applications to run smoothly and to offer a perfect quality of experience. This is due to several fundamental limitations in the design of the current network architecture and communication protocols. As a result, it is now the time to put into question the tenets of today’s Internet and think novel architecture and protocols that take into account recent technological advances in cloud computing, virtualization and network softwarization to design the future Tactile Internet.
In this talk, we start by analyzing the characteristics and requirements of future networking applications and highlight the limitations of the today’s Internet architecture and protocols. We then provide an overview of FlexNGIA, a Flexible Next-Generation Internet Architecture that leverages cloud computing infrastructures, services and technologies as the keystone of the future Internet providing high performance and fully flexibility for future Internet applications and services. We also discuss through some use-cases how FlexNGIA could ensure the performance guarantees required by some of the future network applications.
