Abstract
A method includes determining a radio frequency (RF) fingerprint mapping to an indoor floor plan for an indoor area. The method includes clustering Wi-Fi access point devices deployed in the indoor area into groups of Wi-Fi access point devices based on RF fingerprint data received by at least one reference point device. The method includes selecting a Wi-Fi access point device from each group of Wi-Fi access point devices and determining a RF fingerprint based on the selected Wi-Fi access point devices. The method includes receiving a request for a location associated with a mobile device. The request includes a sampled RF fingerprint associated with the mobile device. The method also includes comparing the RF fingerprints based on the selected Wi-Fi access point devices with the sampled RF fingerprint associated with the mobile device to determine a location of the mobile device within the indoor area.
