Abstract
A method of estimating indoor location of an electronic device is disclosed. The electronic device will detect multiple Wi-Fi signals, each of which originates from a unique Wi-Fi access point in a building. For each of the signals, the system will determine an access point device identifier and a signal strength indicator, retrieve location coordinates for the access point; and various candidate constants to apply to a distance calculation for determining a distance from the electronic device to each of the access points. The system will repeat the distance calculation multiple times for each of the various constants and determine which constant minimizes a loss value. The system will identify a set of coordinates of the electronic device that are associated with the constant that minimizes the loss value, and then use the coordinates to estimate a location of the electronic device within the building.
