In the last few years, multiple research groups (including the group at Rice) have reported the feasibility of short-range full-duplex wireless, i.e. simultaneous transmission and reception of wireless signals in the same frequency band. Furthermore, antenna designs at Rice have pushed the full-duplex transmission ranges to beyond 150 meters and have thus established the feasibility of full-duplex in several scenarios of practical interest. In this talk, we will first discuss our experiment-driven approach to understand the bottlenecks in increasing rate and range of full-duplex communications. The modeling captures the performance of both passive and active cancellation mechanisms used in full-duplex implementations. Finally, we will discuss our ongoing work in leveraging full-duplex capabilities at infrastructure nodes to support half-duplex mobile nodes.

Ashutosh Sabharwal is a Professor in the Department of Electrical and Computer Engineering at Rice University. Throughout the his years at Rice he has been involved in several large research projects focused on wireless networking and supported by funding from NSF, Nokia, Texas Instruments, and Intel Corporation. He received his Ph.D. from the Ohio State University in 1999 and received the Ameritech Dissertation Fellowship for his dissertation work in 1998-99. His research interests are in wireless networks, spanning theoretical foundations, protocols and experimental systems. He is the founder of the WARP project which enables high-performance clean-slate prototyping of wireless networks and is now in use in more than 125 organizations worldwide http://warp.rice.edu.
