Abstract

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.
