Presence detection based on crowd surfing signal strength

摘要

A method includes receiving wireless signals from consumer devices that are in communicable range of the merchant device. The wireless signals each include a unique identifier associated with one of the consumer devices. The method further comprises generating signal strength data that includes one signal strength value associated with the unique identifier of each of the wireless signals, storing the signal strength data in a data storage device, analyzing the signal strength data to determine how many of the consumer devices achieved various signal strength levels, determining a threshold signal strength value based on the analysis, determining a consumer device is present within a physical area when a subsequent wireless signal from a subsequent consumer device is greater than the threshold signal strength value.

1. An apparatus, comprising:
processing circuitry configured to:
determine signal strength data that includes signal strength values associated with wireless signals from consumer devices that are in communicable range of a merchant device;determine presence data associated with at least a portion of the consumer devices detected by the merchant device, wherein the presence data is independent of the signal strength data and indicates that the at least a portion of the consumer devices are within a physical area;determine a threshold signal strength value based, at least in part, on the signal strength data and the presence data;determine second signal strength data that includes second signal strength values associated with a subsequent wireless signal from a consumer device; anddetermine the consumer device present with the physical area when the subsequent wireless signal from the consumer device is greater than the threshold signal strength value.
