Future Non-Terrestrial Networks: Opportunities and Challenges

Tony Q.S. Quek, IEEE Fellow

Fellow of Academy of Engineering Singapore
Cheng Tsang Man Chair Professor
ST Engineering Distinguished Professor
Director, Future Comms R&D Programme
Head of ISTD Pillar
Singapore University of Technology and Design

Abstract
6G wireless networks are envisioned to break the boundaries of the current terrestrial-based networks and integrate with non-terrestrial networks (NTNs). NTN is growing in importance owing to its ability to offer “anything, anytime, anywhere” connectivity, and complement the different aerial platforms for wireless backhaul connectivity, coverage extension, and multi-connectivity for reliability. In this talk, we will provide an overview of NTN and the pathway towards 6G, highlighting some of our recent works in this area. In addition, we will share Singapore’s first national future communications research and development programme (FCP) to jumpstart cutting-edge communications and connectivity research, especially on Open RAN research and development.

Sustainability is now a business imperative that changes EVERYTHING

Abu Baker

Master Technologist, Hewlett-Packard

Abstract
The next generation of high-performance chips for AI, big data, self-driving cars and IoT must use low-power technology for the sake of the Earth. We are doing all we can to overcome the limits of technology to perfect our green processes. Therefore, enterprises that want to make a positive impact on the planet need the right combination of strategic partnerships and AI-infused technology to put their sustainability goals into action. In the race to reduce emissions, consumption, and environmental impacts, companies across sectors are looking to transform their business models by prioritizing sustainability in their core operations and to meet the growing demands of key stakeholders and conscientious customers. But organizations can’t do it alone. The pursuit of net zero can only truly begin when an organization is able to monitor, track, and report on their carbon footprint, energy transition goals, and environmental, social and governance (ESG) data. My presentation will talk through how the transformation to a sustainable future empowered by AI-driven technology can make an impact in the world.

Earth System Science and System Construction

Keiko Takahashi

Waseda University

Abstract
The average global temperature in 2023 is certain to be the hottest in recorded observation history. It has been scientifically clarified in the IPCC report that changes in the global environment, typified by global warming, are the result of long-term effects of human activities on the global environment. This suggests that global environmental changes are the accumulation of human activities, each on a small scale, affecting the entire planet. These global environmental changes are linked to many global issues in our society, such as energy, natural disasters, and food. The Earth can be considered a system. The components of the Earth system are huge, and the relations among them are diverse. Furthermore, it exhibits complex system behavior that is both nonlinear and nonequilibrium. We need to consider from the standpoint of systems science what actions we should take to realize a society that maintains balances with nature to build the earth system as a sustainable system. The world’s water problems have become more serious in recent years. We focus on water circulation system, which is one of the most important systems of the Earth system. We have been able to perform large-scale/small-scale water circulations to clarify where water comes from, what it carries, how it changes phases, and how it behaves and circulates over time and space scales. Our simulations have explored what kind of actions we can take to create a sustainable water environment. In my presentation, I will introduce the water general circulation model that we have been developed, including an overview of atmospheric general circulation model which can explicitly express the process of cloud formation and disappearance, ocean model, and land surface and groundwater system model, and coupled method that interchanges the physical quantities among those models. Furthermore, we will introduce the method for artificial use of water or artificial environmental changes due to human actions into this water general circulation model. Case studies will be presented to illustrate how states of the environment can be changed by altering anthropogenic actions. Based on these results, I would like to introduce future perspectives on Earth system science.
