If they can prove it works at scale this tech instantly eliminates the usefulness of beacons. Wifi has always been the obvious solution to indoor location (lower power than GPS / works indoors / piggybacks on installed hardware / somewhat "open") but fidelity was too low. Hence the rise of beacons. Beacons IMO are the least elegant solution to the problem of indoor location because they require (a) a whole separate location framework (b) requires vendors / stores to install & maintain hardware to drive coverage (c) are owned by the OS. I've been watching this game unfold for years - Apple bought WifiSLAM in 2013 to improve indoor location / wifi (1), and then bought "super accurate GPS" firm coherent NAV last year. (2) There are also several startups attempting to use sensor data + geomagnetic or inertial navigation to solve this problem. (3) If these guys actually got Wifi working, and figure out a way around the callibration problem, they in one fell swoop solved one of the major barriers to the hyper-localized advertising / consumer tracking that we've been promised (threatened with?) for years.
