We've been testing indoor localization for so many years and seen so many false promises. The use cases are so wide and profound. Perhaps this the enterprise product developer's pot of gold.
But then, it works. There's nothing like walking around a building and seeing it right there in your hand. We used a few iBeacons of course, these are the obvious choice for the fine detail work, but they won't work for the larger building. Nor would we want to use them, since that requires "too much" hardware, which mandates both IT and Facilities approval, which torpedoes most enterprise installations.
It's not enough to have indoor localization. You need indoor localization that is politically acceptable to big enterprise organizations.
We'll publish more later in our paper on SAIL (Statistically Acceptable Indoor Localization).
