Prof. Hang Liu of The Catholic University of America

 5G mobile networks are being developed and deployed, and the research on 6G technologies has started. Next-generation (5G and beyond) wireless networks will deliver a data rate much higher than the current networks (multiple Gbps), ultra-low latency (1 msec), and massive capacity. They will significantly improve mobile user experience and support a wide range of new applications, such as autonomous driving, drone swarm, remote surgery, robotic manufacturing, smart cities, massive Internet of Things, augmented/virtual reality (AR/VR), etc. The NSF Industry/University Cooperative Research Center (IUCRC) for Broadband Wireless Access and Applications (BWAC) at the Catholic University of American is working on multiple advanced wireless technologies in collaboration with industrial and academic research partners to enable next-generation mobile communication systems. In this talk, I will introduce how 5G works and present an overview of several enabling technologies, including scalable orthogonal frequency division multiplexing (OFDM), millimeter-wave communications, massive multiple-input and multiple-output (MIMO), dynamic spectrum sharing, and mobile edge computing. Particularly, I will discuss how these technologies work together to significantly increase network capacity, reduce latency, and connect a massive number of devices to support ever growing user demands and new mobile applications.
