ECE Seminar: A Variegated Study of 5G Services: Challenges, Opportunities, and Application Innovations

Speaker: Dr. Feng Qian, Associate Professor, Department of Computer Science and Engineering, University of Minnesota - Twin Cities

Talk Title: A Variegated Study of 5G Services: Challenges, Opportunities, and Application Innovations

Abstract: 5G is expected to support sub-millisecond latency as well as throughput of up to 20 Gbps -- a 100x improvement compared to 4G/LTE. However, there exists a vacuum in understanding how 5G performs "in the wild" and whether it can fulfill its promises. In this talk, I will describe our research thrust of 5G networks since early 2019, when Minneapolis became one of the first two U.S. cities that received commercial 5G deployment. Over the past 3 years, we have experimented with more than 100 TB of 5G data and traveled more than 8,000 km for drive tests. Our studies revealed a complete landscape of 5G across several key dimensions -- network performance, power characteristics, mobility management, application quality-of-experience (QoE), to name a few, with their critical tradeoffs quantitatively revealed. I will then talk about our development of a learning-based framework for accurate 5G performance prediction, and how we innovate emerging applications such as virtual/mixed reality (VR/MR) to improve their QoE on 5G networks.

Biography: As an experimental networking and system researcher, I design, engineer, deploy, evaluate real network systems, and make them yield real-world impact. I am particularly interested in mobile systems, AR/VR, mobile networking, wearable computing, real-world system measurements.

I received my Ph.D. from EECS at University of Michigan in 2012. I am honored to receive several awards including the AT&T Key Contributor Award (2014), NSF CRII Award (2016), Google Faculty Award (2016), ACM CoNEXT Best Paper Award (2016,2018), AT&T VURI Award (2017), NSF CAREER Award (2018), Trustees Teaching Award (2018), DASH-IF Excellence Award (2019), Cisco Research Award (2021), and ACM SIGCOMM Best Student Paper Award (2021). Some of my research prototypes such as mobile Application Resource Optimizer (ARO) have been commercialized and are widely used in academia and industry.
