Interior navigation is a holy grail of navigation. these days. I have had many conversations with professors here at the university about this, and it is currently not achievable without very large infrastructure modifications to buildings. GPS just does not work in doors. Cell is not good enough for triangulation. Even indoor broadcasting is problematic because of multipathing, radio waves bounce all over the place and their arrival time to your receiver can actually be quite off from their actual distance to you.
Bluetooth is OK for basic broadcasting of data, say from a specific store, but still makes for issues with navigation. For example, you could walk into a mall, have the mall load it's map onto your device, then bluetooth transmitters could tell your device what store you are passing close to, and then an app on your device would corelate that with the internal map and begin some form of path planning. This is great, but it again requires a lot of infrastructure changes. Installation and maintenance of all the transmitters, developing and maintaining accurate maps and data for the transmitters, and maintenance of the transmitters. None of this is impossible, nor particularly difficult, we just haven't reached a point where wide spread adoption of this is valuable enough to the stake holders for it to get any traction. I expect it is coming, and it has been demonstrated by Google already, but it will be a while before it is deployed on any scale. -- You received this message because you are subscribed to the "VIPhone" Google Group.
