Patent attributes
Decision trees may be built and executed to estimate an indoor location of a mobile device. In particular, a first attribute (e.g., received signal strength indication (RSSI) of one or more access points) is selected, and variations of that attribute throughout an indoor area are identified. These identified variations are mapped to the locations to generate a model. One or more decision trees are built based on the model, and an output of the decision trees estimates a location of a mobile device within the building. According to one aspect, a plurality of such decision trees may be built, and the outputs provided by the plurality of trees may be averaged to provide a more reliable result. Each of the plurality of trees may vary the attribute being analyzed, data values, or an order in which data is analyzed.
