User dynamics through wi-fi device localization in an indoor environment

An indoor location positioning system comprising:

• at least one processor, wherein a set of Wi-Fi scanners and an RSSI fingerprint database are configured to work with the at least one processor;
• the Wi-Fi scanners are positioned at a plurality of locations within an environment, wherein the environment is partitioned into interconnected zones, wherein the Wi-Fi scanners receive anonymous probe messages from Wi-Fi devices that are present in the environment during a calibration phase of the indoor location positioning system, and wherein RSSI values of the anonymous probe messages received by the Wi-Fi scanners are collated to create RSSI fingerprints corresponding to the different locations respectively;
• wherein one or more of the Wi-Fi scanners are used as anchor scanners to counter the difference in transmit power levels of different Wi-Fi devices that result in different RSSI fingerprints for the different types of Wi-Fi devices, wherein the RSSI value at each anchor scanner is subtracted from the RSSI values at rest of the Wi-Fi scanners to generate the RSSI fingerprint;
• the RSSI fingerprint database is generated after the calibration phase that contains the generated RSSI fingerprints corresponding to the different locations;
• and
• the processor, after the calibration phase, matches the RSSI fingerprint of the anonymous probe messages from the Wi-Fi devices against the RSSI fingerprints recorded during the calibration phase to predict the location of the Wi-Fi device in a prediction phase.
