Location based retail media and ad attribution system

A method comprising:

• determining, at a ranging sensor controller, a plurality of locations of a user device within a premises, said user device associated with a user device identifier wherein determining the plurality of locations is performed by receiving signal strengths, an angle of arrival, a time difference between times of arrival of a radio signal and an above or below orientation of the user device relative to a product based on ranging sensors distributed throughout the premises and determining a user device journey based on the plurality of locations within the premises and a dwell time at each of the plurality of locations;
• communicating the user device identifier and the plurality of locations to an on-premises controller;
• matching a user profile to the user device identifier at a controller;
• identifying the product associated with the journey of the user device at the controller;
• communicating product data associated with the product to the controller;
• and
• communicating an advertisement to the user device from the controller based on the product data,
• wherein the on-premises controller determines a RF path and a camera path using images and the ranging signals to form a comparison to continually identify the user device within the premises.
