Time: 10:00 – 13:00 SGT

Location: SUTD Campus, 8 Somapah Rd, Singapore


Aligning existing and future mobile communication systems to serve sustainability is a central vision of the WWRF for the benefit of the humanity. Connectivity and telecom systems play a central role to achieve sustainability goals. In its Vision 2030 SDG (Sustainability Development Goals), the United Nations has proclaimed access to the Internet as a basic human right and has said that these goals cannot be achieved without affordable access to the Internet by everyone. We view sustainability in a broad context, similar to what the United Nations has done, and are focusing to address as many goals as possible out of the 17 goals defined by the UN in the realization of Beyond 5G and 6G communication.

The workshop has been organized for the duration of 3 hours with a coffee break of 25 minutes. There will be up to five invited speakers, each focusing on the role of communications technology on one or more SDG goals. The workshop will end with a panel discussion with all the invited speakers.

Professor Timothy O’Farrell, Chair in Wireless Communication, University of Sheffield

Talk title: A Decade of Green Radio and the Path to “Net Zero” in Future Wireless Networks

Abstract: It has been over a decade since several major research projects, such as the UK Green Radio, EU EARTH and GreenTouch projects, initiated large scale investigations into energy efficient wireless networking. Moving forward, the recent Climate Change Conference in Glasgow (COP26) has started to flesh out the details of meeting the ambitious goals of the 2015 Paris (COP22) agreement. This talk reflects on the achievements of energy efficient wireless research to date in mitigating carbon emissions. It explores the industrial challenges ahead with the deployment of fifth generation (5G) wireless technologies and discusses potential opportunities for reducing carbon emissions in the next decade. Major research challenges that still face the wireless community are also described including the development of sixth generation (6G) wireless technologies.

Bio: Professor Timothy O’Farrell currently holds the Chair in Wireless Communication at the Department of Electronic and Electrical Engineering, University of Sheffield, UK. He specializes in the design of energy efficient wireless networks, direct digitisation in multiband software defined radios, and waveform design for wireless communication systems. To date, he has published over 335 papers and led 26major research projects on these topics. Professor O’Farrell was Academic Coordinator of the mVCE Green Radio project (2009-12); General Chair of the 5th International Workshop on Next Generation Green Wireless Networks (Next-GWiN 2018); and director of the UK Research Strategy Community Organisation in Communications, Mobile Computing and Networking (CommNet2, 2015-19). He is a chair of the GreenNet workshop at the IEEE International Conference on Communications in Rome 2023. He is director of the UKRI National 6G Radio Systems Facility, a director of the mVCE (; and a member of the DSIT College of Experts ( advising the UK government on wireless digital infrastructure.

Dr Shah Kwok Wei, Director, Center for 5G Digital Building Technology, National University of Singapore.

Title: Harnessing 5G and Beyond for Singapore’s Future Built Environment

Abstract: Singapore’s future digital transformation of the built environment industry and facilities management industry is poised to benefit from the adoption of 5G technology, which offers ultra-fast speeds, low latency, and high reliability for real-time monitoring and control of building systems.

Bio: Dr Shah Kwok Wei is presently Assistant Professor, currently Director, Center for 5G Digital Building Technology, under Dept. of the Built Environment (NUS ranked 6th Global for Built Environment under QS), and was previously Deputy Program Director under the Department of Building, School of Design and Environment, National University of Singapore NUS. Dr Shah is currently Visiting Associate Professor at Sichuan Agricultural University. Dr Shah was previously Advisory Board member of Vietnam Green Building Council (VGBC) and sat on VGBC Education Committee. Dr Shah was previously lecturer for Real Estate and Developers Association of Malaysia REHDA GreenRE in Malaysia and PhD Co-Supervisor of University Technology of Malaysia, UTM. He was Visiting Professor at Tianjin University of Technology and now Sichuan Agriculture University, China. He is invited as Overseas Distinguish Visiting Professor of HCMC University of Technology in Ho Chi Minh, Vietnam. He is appointed BCA Ambassador under Building & Construction Authority of Singapore and a member of SPRING and SGBC technical committees. Dr Shah served as technical consultant for Ascendas Services Pte Ltd, and now Asahi Glass Corporation (world largest glass manufacturer), and Chief Technical Advisor for Bronx Culture Pte Ltd and AlphaBiomedical Pte Ltd fabricating biomedical nano-sensors. Dr Shah is the Founder CEO of a new NUS university startup NanoDyne Pte Ltd which specializes in fabricating anti-corona virus nanocoating films for companies such as F&N and City Development Ltd. Dr Shah’ research interest is on 5G digital technology, nanotechnology and nanomaterials for green building applications.

In 2015, Dr Shah was awarded “Young Green Innovator of the Year 2015” under the Singapore’s BCA-SGBC Green Building Individual Awards. In 2014, Dr Shah’s phase change technology won two awards at Startup Asia Awards 2014 for “Most Promising Idea” and “Most Attractive for Investment” Awards. Dr Shah’s focus is leverage on phase change materials, nanomaterials, nanotechnology and biomaterials to develop next generation smart building materials for enhanced properties and high performance such as energy storage, durability, thermal conductivity, plasmonic, photocatalytic, thermal insulation, noise insulation, urban heat mitigation, self-cleaning, air-purification, self-healing, anti-virus and anti-bacterial material properties and capabilities. Dr Shah is also leading the Centre for Digital Building Technology under the Department of Built Environment (DBE) which is looking at harnessing 5G to advance learning, research and industry solutions. With the ultra-reliable low-latency communications and significant improvements in bandwidth performance offered by 5G, the 5G Lab looks for and makes possible new applications that utilize drones, artificial intelligence (AI), augmented and virtual reality (AR, VR) and internet of things (IoT) in creating safe, green and sustainable built environments and facilities.

Mehul Motani, Associate Professor, Electrical and Computer Engineering Department, National University of Singapore (NUS)

Title: I^3: A Case for Unifying B5G/6G and AI

Abstract: In this talk, we will explore the role of B5G/6G communications in addressing the UN Sustainable Development Goals (SDGs) and how AI will be a key enabler in this process. We refer to this view as I^3 (Internet-Information-Intelligence), which leverages the power of AI to transform how we access, interact with, and utilize information on the Internet. I^3 can empower individuals with access to the internet, education, and AI, as a pathway out of poverty and other social challenges. Critically, I^3 requires new skills and ways of thinking to effectively and responsibly use the myriad of recently wildly popular generative AI applications (e.g., chatGPT). We will also highlight the interplay between I^3 and semantic communications, emphasizing the pivotal role of communications as the backbone of this new approach.
