This talk will cover my research in millimeter-wave IoT systems aiming for high-speed IoT communication while maintaining low power consumption, which has been a difficult problem to address. In recent years, two clear trends have emerged in the field of wireless communication and mobile systems. One trend focuses on achieving high-speed wireless communication with high-power consumption, exemplified by technologies like 5G, 6G, 802.11ad/ay, and others. Concurrently, there is another strong trend towards low-power wireless communication with low-speed, as seen in RFID technology, often referred to as backscatter. As these trends aim towards two opposite directions, achieving high-speed and low-power wireless communication becomes a fundamentally challenging problem. My research is dedicated to bridging the gap between these contrasting trends.

In this talk, I will present my research on developing millimeter-wave IoT systems. Specifically, I will outline three main contributions of my research: (i) discussing how our proposed system achieves high-speed millimeter-wave IoT communication using a commercial WiFi network without any hardware or protocol modification; (ii) illustrating how we leverage the large bandwidth of millimeter-wave to support massively scalable IoT communication; and (iii) introducing our millimeter-wave IoT application, which provides energy-efficient, concurrent, multi-user beamforming of deployed millimeter wave WiFi devices. Finally, I will briefly introduce my other projects and future works.


Yoon Chae is a Ph.D. candidate in the Computer Science Department at George Mason University, advised by Professor Parth Pathak. He is interested in shaping the future of wireless communication and Internet of Things (IoT) systems, particularly focusing on the evolution of the next-generation millimeter wave IoT systems. His research focuses on designing high-speed and low-power mmWave IoT systems. He is equally committed to their practical implementation and the development of innovative solutions using physical layer information. His work has been published at top-tier conferences including NSDI, Mobicom, Mobisys, and Sensys. He has also received the best paper award at Mobisys 2022.
