Indoor positioning is, in many ways, an inside version of the satellite-navigation apps we rely on for outdoor navigation, but with an added twist – it can also be used to help locate people and things.

Let’s say you’re at home and misplaced your car keys, or you’re in a grocery store and can’t find your favorite brand of coffee. Or maybe you’re working in a factory and need a particular tool from a storage bin, or you’re a site manager dealing with an emergency and need to make sure everyone’s exited the building. Indoor positioning helps in all these situations, because it can locate items and guide you to where they are.
