Lighting up Wireless Communication and Sensing
This event has passed.
Thursday, March 25, 2021 - 12:00pm to 1:00pm
We are entering a post-smartphone era, where zillions of new wireless devices compete for the already limited radio spectrum (RF) to obtain wireless connectivity. Addressing the problem of spectrum crunch demands radical new thinking. In this talk, speaker Xia Zhou will present her journey in exploring light as a new spectrum territory, which provides ten thousand times wider bandwidth than RF for wireless communication. Additionally, the physical properties of light offer unique benefits for object tracking and behavioral sensing. Dr. Zhou will highlight two recent works as examples on light-based communication and sensing. The first work exploits laser light to enable bi-directional, high-bandwidth air-water communication to facilitate underwater robotic operations. The second work advances light sensing to enable noninvasive glucose sensing for diabetic patients using portable, low-cost, and off-the-shelf hardware. Dr. Zhou will conclude with open challenges and ongoing work. Bio Summary: Xia Zhou is an Associate Professor in the Department of Computer Science at Dartmouth College, where she co-directs the Dartmouth Networking and Ubiquitous (DartNets) Laboratory and Dartmouth Reality and Robotics Lab (RLab).
