  • Patent number: 10997120
    Abstract: Disclosed are systems, methods, and computer-readable media for determining a distribution of various visiting frequencies among devices/elements detected at a site. A method includes generating a list representing a portion of devices detected at a site over a first time period based on wireless signals transmitted by the devices and received at an access point and determining a visiting frequency for each device represented in the list based on data representing devices previously detected at the site. The method further includes, based on the visiting frequency determined for each device represented in the list, estimating a distribution of each visiting frequency among the devices detected at the site over the first time period to yield a plurality of estimated distributions and storing the plurality of estimated distributions for further processing.
