Answer 1

Inhouse navigation (or navigation if no GPS signal is available) is often done using WLAN triangulation. You need to scan the WLANs in the building to build a map of field strength of the various WLAN signals for specific locations. During navigation the map is used to determine the most likely position for a given reading of WLAN signals.

E.g. Google is working on an inhouse navigation service and there are some companies offering inhouse navigation solutions.

Answer 2

You can use QRCode based pseudo-location. User scans QRCode in one room of the building and the app is aware of phone's location.
