Abstract:
1. A method comprising: wirelessly receiving, at a mobile computing device of a user, a plurality of limited range signals from a plurality of limited range wireless transmitters located at a plurality of elevations within a real estate property, each limited range signal having information about the real estate property such that a plurality of the limited range signals have different information about the real estate property, each limited range signal also having data indicative of the elevation for the limited range wireless transmitter which transmitted the limited range signal; the mobile computing device calculating a signal strength for the plurality of received limited range signals; the mobile computing device extracting the elevation-indicative data from the received limited range signals; the mobile computing device determining a plurality of elevations attributable to the limited range wireless transmitters based on the elevation-indicative data extracted from the received limited range signals; the mobile computing device determining an elevation attributable to a current position for mobile computing device; the mobile computing device comparing the determined elevations for the limited range wireless transmitters with the determined elevation for the mobile computing device; the mobile computing device determining which of the received limited range signals is from a limited range wireless transmitter having a correspondence in elevation with the mobile computing device; the mobile computing device selecting a limited range signal from among the plurality of received limited range signals based at least in part on the calculated signal strengths and the elevations attributable to the limited range wireless transmitters such that the selected limited range signal is a limited range signal from a limited range wireless transmitter determined to have a correspondence in elevation with the mobile computing device; and based on the information about the real estate property from the selected limited range signal, the mobile computing device generating data for a visual display about the real estate property for consumption by the user through a display screen of the mobile computing device.
