The talk argues that disruptive innovations in the wireless domain
require a cross-layer approach, where higher-level protocols and
applications are designed with an understanding of signal propagation,
and transmission systems are adapted to application needs. I will discuss
a few systems that leverage this approach to deliver practical solutions
to the challenges facing wireless communications and mobile computing.
MegaMIMO enables independent devices to act as one humongous MIMO
transmitter, delivering 10x higher data rates for WiFi and cellular
networks. WiTrack a system that provides 3D motion tracking of a person
based purely on RF reflections off her body. It works across walls and
obstacles and does not require the user to carry any wireless device.
Finally, PinIt a system that can localize objects in the environment to
within 10 cm and track their motion and orientation.
Dina Katabi is the Andrew & Erna Viterbi Professor of Electrical
Engineering and Computer Science, and the director of the MIT¹s center
for wireless networks and mobile computing (Wireless@MIT). She received
her PhD and MS from MIT in 2003 and 1999, and her Bachelor of Science
from Damascus University in 1995. Katabi was named a MacArthur Fellow in
2013. She received the ACM Grace Murray Hopper Award in 2013, a Faculty
Research Innovation Fellowship in 2011, the IEEE William R. Bennett prize
in 2009, a Sloan Fellowship in 2006, the NBX Career Development chair in
2006, and an NSF CAREER award in 2005. Katabi's doctoral dissertation won
an ACM Honorable Mention award and a Sprowls award for academic
excellence. She also received multiple best paper awards from ACM SIGCOMM
and Usenix NSDI, and a TR10 award for her work on the sparse Fourier
transform. A couple of start-ups have come out of Katabi's lab such as
PiCharging and Emerald, which was recently presented to President Obama
in the White House.
