Wireless networks are everywhere around us and form a big part of
our day-to-day lives. In this talk, I will present my work on exploiting
new opportunities emerging from modern wireless networks.
Specifically, can we use the ubiquitous Wi-Fi infrastructure around us
to deliver new services, beyond communication? This talk focuses on
indoor positioning, a service that has grabbed the attention of the
academia and industry. While GPS has revolutionized outdoor
navigation, it does not work indoors. Past work that has explored this
problem is either limited in accuracy with errors of several meters, or
advocates complete overhaul of the infrastructure with massive
antenna-array access points that do not exist on consumer devices. I
will present Ubicarse, which inspired by radar systems is the first
purely-software indoor positioning system for existing Wi-Fi devices
that achieves tens of cm in positioning accuracy. I will then present
Chronos which achieves accurate positioning between a single pair of
commodity Wi-Fi devices without support from a third party. Finally, I
will describe how these systems open up new opportunities in the
context of robotic navigation and security.

Swarun Kumar is an assistant professor at CMU where he works on
wireless networks and systems. He designs and builds novel systems
that leverage a deep understanding of the wireless physical layer to
enable faster wireless networks and new services. His work has been
featured as research highlights in the Communications of the ACM
(CACM) and the International Journal of Robotics Research (IJRR).
Swarun is a recipient of the George Sprowls Award for best Ph.D
thesis in Computer Science at MIT and the President of India gold
medal at IIT Madras.
