Abstract: The subject technology determines population density of an area in order to map one or more persons to smaller areas such as bathrooms, stores, and lines. Based on a user's current geolocation, the subject technology utilizes one or more nearby wireless signals transmitted from computing devices to determine a population density of an area near the user's geolocation. The signals from each device can include unique IDs for identifying the device associated with the ID. Mobile devices such as cell phones constantly broadcast a cell signal and/or other types of signals with unique identifiers. These signals are anonymized to protect any personal information associated with the mobile devices transmitting these signals while still being able associate a device to a respective signal. The subject technology therefore can determine an area's population density based on these anonymized signals by detecting one or more associated devices near the geolocation of the user.
