INDOOR LOCALIZATION OF MOBILE DEVICES
First Claim
1. A method comprising:
- receiving, by one or more processors, one or more wireless network access point identifiers and signal strengths associated with the one or more wireless network access point identifiers for a geographic area;
quantizing, by the one or more processors, the received signal strengths into a plurality of quantized received signal strengths for each associated received wireless network access point identifiers;
generating, by the one or more processors, a set of voting maps of signal strengths for each received wireless network access point identifiers and quantized received signal strength.

Abstract
Aspects of this disclosure provide systems and methods for generating models of a wireless network environment in an indoor space which may be used to predict an indoor location. The disclosure relates to collecting wireless network access point identifier information and power level observed at various locations are collected to generate various signal maps. The signal maps may be used to generate models of the indoor space. In one example, a voting model may use a probability distribution of a plurality of signal maps in order to identify a location with a highest probability of overlap with current signals received at a client device. Once a location has been identified, it may be used to assist with any number of navigational functions, such as providing turn by turn directions to another indoor location, for example, a conference room or exit, or simply providing information about the current location.
