EE Seminar: Connecting Farms, Forests, and Cities with New Approaches to Wireless Communication and Sensing

March 10, 2022
10:00 AM - 11:00 AM

Abstract: The Internet of Things (IoT) plays a critical role in connecting society to the digital world. Billions of IoT devices are used today to enable applications from smart homes and cities to digital healthcare and smart agriculture. While we have seen significant benefits, to fully realize the potential of these systems we need to address a key challenge: enabling power and connectivity for resource-constrained environments.  How can we collect data in remote forests, farms, or even oceans where there is no Internet connectivity or access to power? 

In this talk, I will present two examples of my research that address this challenge. First, I will present FarmBeats, a system that enables seamless data collection by using new technologies such as TV White Spaces for communication and low-power sensors for data collection. FarmBeats is designed to enable data-driven agriculture techniques for farms that are located in areas that lack power and connectivity infrastructure. I have deployed the FarmBeats system across the United States and Europe, and we have demonstrated that the system can provide significant benefits for farms in the form of cost savings and productivity. Finally, I talk about enabling battery-free sensing using novel passive wireless communication techniques. Conventional communication techniques view noise sources as something that harms wireless communication capacity and something that needs to be eliminated. On the contrary, it is possible to use noise to enable low-power communication on resource-constrained devices. I will present the design and implementation of the first passive wireless communication system that uses modulated Johnson (thermal) noise. I will conclude the talk with future research directions, including further applications for smart agriculture, healthcare, and space.
