I wanted to put the emphasis that the original idea of openBmap was to get a map of all communicating objects (RFID, future things, ...). Nevertheless here are some examples of static BT points we may encounter pretty soon:
* some experiments have been carried on in Paris subway about BT beacons which help blind people find their ways in the labyrinth. They have a special device at the ear, which says where they are, and if they go in the wrong direction, etc... * ad panels in the subway, or on the street, may have bluetooth to distribute details to phones * in Paris, there are BT stations on the street, you can get connected to with your phone, and download maps and or details of the area you currently are. A reason why BT may still last over WiFi may be the power needed to have BT on in comparison of WiFi, don't you think? If anybody sees more examples...
