Speaker: Sachin Katti

Bio: Sachin Katti is an Assistant Professor of Electrical Engineering and Computer Science at Stanford University and also the CEO of Kumu Networks which is commercializing his research on full duplex radios. He received his PhD in EECS from MIT in 2009. His research focuses on designing and building next generation high capacity wireless networks by combining techniques from information and coding theory, RF systems, and networking. His dissertation research focused on redesigning wireless mesh networks with network coding as the central unifying design paradigm. The dissertation won the 2008 ACM Doctoral Dissertation Award - Honorable Mention and the George Sprowls Award for Best Doctoral Dissertation in EECS at MIT. His research has won numerous awards, including the IEEE William Bennett Prize, the Best Student Paper Award at ACM SIGCOMM 2012, USENIX ATC 2013, the Sloan Fellowship, the NSF Career Award as well as Okawa, Hooover, Packard and Terman Faculty Fellowships.

Title: Self-Interference Cancellation Technology

Abstract: A basic precept of wireless communications is that radios cannot transmit and receive at the same time on the same frequency. This long-held assumption has informed several aspects of wireless: from radio design, to PHY, MAC and network layer designs for all kinds of wireless networks. In this talk, I will describe our research on invalidating this fundamental assumption. Specifically, I will describe the evolution of our research on self-interference cancellation over the last three years which has now shown that realizing in-band full duplex radios is possible and practical, and discuss the impact this is beginning to have on future wireless network architectures. I will also highlight the cross-disciplinary nature of the research spanning RF, DSP, PHY and MAC, and discuss both the challenges and opportunities in attacking problems that span several disciplines.

Speaker: Joel Brand

Bio: Joel Brand is Vice President of Product Management at Kumu Networks. For 20 years Joel has actively participated in defining and building infrastructure solutions for the telecom and wireless industries. He previously held executive positions at ConteXtream, Bytemobile (acquired by Citrix) and Ruckus Wireless (NYSE: RKUS). Joel holds a B.Sc. and M.Sc. in Engineering from the Israeli Institute of Technology (the Technion) as well as MBA from National University in San Diego.

Title: Applications of Full Duplex Radios

Abstract: Self-interference has significant impact on the design of wireless communications systems. It necessitates the isolation of transmit and receive signals, using components such as duplexers, policies such as time division duplexing, or simply through spatial separation of antennas. All currently known techniques negatively affect efficiency, for example in the form of spectral utilization and loss, increase system costs, and limit deployment models. The session will discuss the implications of self-interference cancellation technology to a wide variety of communications applications, and explore an array of possibilities to use the technology in the confines of existing standards.
