Abstract:
Unlocking the true potential of Millimeter-wave frequencies for applications such as automotive vehicles and AR/VR requires overcoming significant challenges. Despite their high bandwidth, today's mmWave networks struggle to meet the stringent requirements of these applications due to limitations in providing reliable and scalable connections. The challenge lies in managing directional beams that combat high path loss but limit deployment due to occlusion and inefficient resource distribution, which only allows serving one user direction at a time.
To address these challenges, I have developed novel multi-beamforming techniques, including blockage-resilient multi-beams (mmReliable, Sigcomm’21) and frequency-dependent multi-beams (mmFlexible, Infocom’23). Empowered by a new radio architecture based on true-time delays, this system facilitates efficient and flexible distribution of time-frequency resources among multiple users, resulting in improved latency and seamless scalability to accommodate numerous devices. I further develop systems and algorithms for wireless sensing using existing network infrastructure and explore security vulnerabilities in communication and sensing systems from physical attacks such as spoofing and jamming. Additionally, I have successfully built multiple testbeds for communication, sensing, and security, including a 28 GHz mmWave testbed using off-the-shelf phased arrays and SDRs. In this talk, I will elaborate on how these experimental platforms not only demonstrated the efficacy of our schemes in practical environments, but also inspired the development of new algorithms, hardware architectures, and applications with tangible real-world impact.
