Something that's not entirely clear to me from the article: is this how Google's new indoor maps stuff works? If so, can someone reconcile that what's described is a way for the infrastructure to track the handsets, that the handsets are still anonymous, and that the maps run on the handset (so unless I'm missing a link, the system must be passing data to the handset).
- fennecfoxen 15y agoGoogle's new indoor maps stuff is implemented at the map layer. They don't have the infrastructure in place to track your wifi from a location's sensors and then communicate that back to the phone. It's just whatever physical-location technology is already built into your phone (typically some combination of GPS, cellular, and a list of what wifi access points are available), plus an indoor floorplan.
