Date: 24th May 2018 (Thursday) | Time: 10:00 a.m. – 11:30 a.m. (Registration at 9:30 a.m.) | Venue: Lim Por Yen Lecture Theatre 2 (N002), G/F, Block N, PolyU (Campus Map)


What smart impact will future 5G and IoT bring to our lives? Many may wonder, and even speculate, but do we really know? With more and more bandwidth readily available for the next generation of wireless applications, many more smart applications/services unimaginable today may be possible. In this talk, we will show that with more bandwidth, one can see many multi-paths, which can serve as hundreds of virtual antennas that can be leveraged as new degrees of freedom for smart life. Together with the fundamental physical principle of time reversal to focus energy to some specific positions and the use of machine learning, a revolutionary radio analytic platform can be built to enable many cutting-edge IoT applications that have been envisioned for a long time, but have never been achieved.

We will show the world’s first ever centimeter-accuracy wireless indoor positioning systems that can offer indoor GPS-like capability to track human or any indoor objects without any infrastructure, as long as WiFi or LTE is available. Such a technology forms the core of a smart radios platform that can be applied to home/office monitoring/security, radio human biometrics, vital signs detection, wireless charging, and 5G communications. In essence, in the future of wireless world, communication, as we see it, will be just a small component of what’s possible. There are many more magic-like smart applications that can be made possible, allowing us to decipher our surrounding world with a new “sixth sense”. Some demo videos will be shown to illustrate the future of smart radios for smart life.
