We have such initial system in place in Helsinki-Vantaa airport, Finland. It is combination of wifi tracking + 300 iBeacons. http://www.theage.com.au/travel/travel-planning/travel-news/helsinki-airport-introduces-worlds-first-passenger-tracking-system-20140730-3ctis.html . It would be nice to be able to use this setup also to guide visually impaired. Now press is more concerned about privacy.
