Abstract:
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; receiving, by the one or more processors, information identifying one or more wireless network access point identifiers and associated signal strengths; quantizing, by the one or more processors, the signal strengths of the identified one or more wireless network access point identifiers to obtain quantized identified signal strengths; selecting, by the one or more processors, one or more voting maps of the set of received voting maps based upon the identified one or more wireless network access point identifiers; and identifying, by the one or more processors, the current location of a client device based on the selected one or more voting maps.
