Systems and methods for indoor geolocation based on yield of RF signals
First Claim
1. A method for determining a user'"'"'s location within an indoor environment comprising:
- receiving a location request including data related to a set of radio frequency (RF) signals;
selecting a map from a plurality of maps based on the received data; and
processing the received data to identify the location of the user on the map,wherein at least one of the map selection and the location identification comprises processing the received data based on yield information associated with at least a subset of the set of received signals identified in the requests.

Abstract
Systems and methods are disclosed herein for determining a user'"'"'s location within an indoor environment. In particular, the system receives a location request including a set of radio frequency signal data collected by a mobile device inside of an indoor environment. Using this data set, the system first selects a map from a plurality of maps stored in a map database. The system then processes the data to identify the user'"'"'s location on the selected map. The system uses yield information associated with the received signals in determining the map that the user is on, the user'"'"'s location on the map, or both the map and the user'"'"'s location to filter out transient signals and identify those signals that are reliably indicative of the user'"'"'s location.
