Transforming communication using backscatter
Barkhausen-Bau, Room BAR E64A , Helmholtzstraße 18 , 01069 Dresden
I will talk about using passive antenna-based surfaces for assisting wireless communications and also opportunistically use them for doing wifi backscatter communication. I will start by presenting my work: ScatterMIMO to enable virtual MIMO using smart surfaces where I have built a smart surface using an array of low-cost antennas to increase the MIMO gain and realize the multiplexing capability of a MIMO communication system. Next, I will talk about how we can use these surfaces to enable a new modality of semi-passive backscatter communication and their use in sensor networks. To this end, I will talk about the challenges in using the backscatter tags with commodity WiFi infrastructure and my work SyncScatter, a low-power hierarchical wakeup solution developed to address this issue.
Manideep Dunna is a fourth-year Ph.D. candidate in Electrical and Computer Engineering at the University of California, San Diego. He received his B.Tech and M.Tech degrees from the Indian Institute of Technology, Madras. His research interests are in low-power wireless communications and sensing with a focus on using the RF backscatter technique to enable them. He is actively involved in projects to design semi-passive backscatter tags and use WiFi access points to communicate with them. Also, he worked on projects related to developing antenna-based reflective surfaces to assist wireless communications. His works got published in networking and systems conferences like NSDI and Mobicom and solid-state circuits conferences like ISSCC.
This talk is hosted by Prof. Marco Zimmerling.
Everybody interested is cordially invited!
