What Is Indoor GPS and How Does It Work?

Finding your way around the world has never been easier, whether you’re plotting out an ocean voyage or just trying to find your way to a new restaurant on the other side of town. Global positioning is so fast and ubiquitous that it’s like magic, but the spell is too often broken the moment we step inside the doors of our favorite shopping establishments. Once indoors, visitors have to resort to not-so-21st-century solutions such as flagging down employees for directions or hoping a map kiosk is up to date. For store planners and retail location managers, it would be so much simpler if indoor GPS worked just as well as its outdoor cousin.
