5G/mm-wave for Long Range Wirelessly Powered Communications, Localization, and Sensing

Presenter: Aline Eid, University of Michigan

Abstract: The notion of intelligent and sustainable infrastructures has ignited growing interest among technologists, policymakers, and urban communities. However, achieving this vision demands computerized systems capable of gathering data on an unprecedented scale and autonomous systems equipped with heightened situational awareness and minimal latency. While the Internet of Things (IoT) promises to deploy 50 billion devices by 2030, realizing this objective would necessitate several trillion wireless devices—an endeavor complicated by the cost, performance limitations, and environmentally harmful battery requirements of current IoT devices. A transformative paradigm is required: one that can spawn expansive, responsive environments capable of dynamically responding to distant electromagnetic signals, thereby enabling remote sensing and imaging—a paradigm we refer to as the "responsive surface."
Learn how we can construct systems facilitating ubiquitous wireless power delivery to responsive surfaces and enabling their ultra-low-power data communication using planar-lens-based antenna systems, harnessed by the millimeter-wave beams of 5G networks. Specifically, hear about the groundbreaking concept our team has introduced, "5G as a wireless power grid," a solution that defies conventional paradigms at millimeter-wave frequencies, transcending the usual trade-off between rectenna angular coverage and activation sensitivity. Additionally, how our mmID technology has the potential to serve as a catalyst for zero-power long-range sensing and localization for digital twins will be showcased. Learn about Eid's latest research endeavors focused on fusing augmented reality (AR) with radio frequencies to enable non line-of-sight human perception.
