Abstract
Methods and apparatus to monitor shoppers in a retail environment are disclosed herein. In a disclosed example method, a first signal is transmitted via a first device in a first direction to a second device and a second signal is transmitted via the first device in a second direction to a third device associated with a shopper. A direction of travel of the third device is determined based on the first signal and a path of travel of the third device through a monitored establishment is determined based on the second signal.

A method, comprising:
- determining a direction of travel of a third device associated with a shopper based on a first signal transmitted via a first device in a first direction to a second device;
- and
- determining a path of travel of the third device through a monitored establishment based on a second signal transmitted via the first device in a second direction to the third device.
A system, comprising:
- a first device to transmit a first signal via a first source in a first direction and a second signal via a second source in a second direction;
- a second device to receive the first signal and determine a direction of travel of a shopper based on detecting an interruption of the reception of the first signal at the second device;
