Google maps allows google to add your location to their knowledge graph in various ways (real time, plans, favorites, etc). It's so well done that it would take a herculean effort to create a competitor map service (see OSM). Amazon can't compete here, I suspect. I'm not a wlan engineer. Can someone smarter tell me if this tech can be used to expand Amazon's location knowledge to track non-user devices more intelligently, i.e. across neighborhoods?
