[Invited Talk] Pushing the Limits of Indoor Localization in Today's Wi-Fi Networks
Jie Xiong (SMU)
Abstract (in Japanese) (See Japanese page) 
(in English) Wireless networks are ubiquitous nowadays and play an increasingly important role in our everyday life. A lot of wonderful emerging applications heavily reply on Wi-Fi and require an even more sophisticated Wi-Fi network. These applications include wearable, augmented reality, indoor navigation and etc. One key component for the success of these applications is accurate indoor localization. While we have GPS in the outdoor environment, indoor localization at a sub-meter granularity remains challenging due to a number of factors, including the presence of strong wireless reflections indoors and the burden of deploying and maintaining any additional location service infrastructure. The recent trend of dramatically increasing number of antennas and higher bandwidths at the indoor access point, brings us unique opportunities to improve the indoor localization performance. Two indoor localization systems will be introduced in this talk. The first, ArrayTrack, is the first localization system hosted on Wi-Fi infrastructure to achieve an accuracy below 30 cm via a novel reflection-path identification scheme. ToneTrack is another system, which breaks the bandwidth limit on time-based localization by combining data from adjacent channels.
