Analyzing movement of data collectors/gateways associated with retail displays

This invention describes a system for tracking wireless data collection devices, such as network gateways, placed at specific spots in a retail store. Each device has a processor and antennas to pick up wireless signals containing data packets. The claims specifically focus on these data collection devices and their ability to receive wireless signals, rather than the broader system of beacons, mobile content, or movement detection mentioned in the abstract.
