Tutorial: Backscatter Communication Techniques for Internet of Things

This tutorial gives you 3 IEEE Professional Development Hours.

Time: 8:30am – 12pm

In this tutorial we will discuss two recent backscatter communication techniques; ambient backscatter and WiFi backscatter and their application to Internet of Things. Unlike RFID technology, ambient backscatter and WiFi backscatter do not require a dedicated specialized reader infrastructure. Ambient backscatter enables communication between two battery free device using ambient signals such as TV and WiFi backscatter provides connectivity between battery free devices and off the shelf WiFi devices. These solutions can lead to a low cost ubiquitous communication solution for Internet of things (IoT). During the tutorial we will discuss the motivation, theory, system design, hardware and protocol design, results and use case scenarios for the two techniques. Finally for each technique will illustrate a representation use case scenario with live demonstration.

About the Presenters

TallaVamsi Talla received his B.Tech degree in Electronics and Communication Engineering from Indian institute of Technology Guwahati, India in 2009 and M.S. in Electrical Engineering from University of Washington, Seattle in 2012. He is currently working towards his PhD degree in Electrical Engineering at the University of Washington, Seattle.

His research interests lie in design of circuits and systems for wireless power transfer for implanted biomedical devices, RF energy harvesting and low power sensing and communication. Vamsi was awarded the QUALCOMM Innovation Fellowship and Intel PhD fellowship in 2014.

KelloggBryce Kellogg was born in Seattle, Washington and earned Bachelors in Electrical Engineering and a Bachelors in Computer Engineering in 2013 from the University of Washington. He is currently pursuing Ph.D. in Electrical Engineering from the UW.

His research interests revolve around ultra-low-power intelligent systems and the devices and techniques required to expand their role in the computing world. This includes topics such as low-power sensing, RF power harvesting, battery-free platforms, and ultra-low-power wireless communication.
