Claim Text:
1. A marketing system comprising: a first communication part being provided to a user terminal owned by a user, and sending a radio wave including a terminal ID of the user terminal regularly; a second communication part being provided to a Wi-Fi sensor installed in a specific area, and receiving a radio wave sent by the user terminal of the user who entered in the area; a transmission part being provided to the Wi-Fi sensor, and transmitting communication information including the terminal ID of the user terminal, a unit ID of the Wi-Fi sensor and radio wave intensity to a server through a network, the radio wave intensity being an intensity of the radio wave and meaning a proximity sorted for plural stages depending on a distance between the user terminal and the Wi-Fi sensor when the user terminal performs short-distance wireless communication to the Wi-Fi sensor through a radio wave; a collection part being provided to the server, and collecting a chronological change of the radio wave intensity in the terminal ID of the communication information concerned with the unit ID of the communication information when receiving the communication information; a calculation part being provided to the server, drawing a circle or a ring of which a radius is a distance corresponding to the radio wave intensity on a center of the Wi-Fi sensor of the unit ID virtually based on a collected radio wave intensity in the terminal ID concerned with the unit ID, calculating position information on the circle or the ring as a part of a flow line on which the user moved, and calculating a flow time when the user stays on the part of the flow line based on the chronological change of the radio wave intensity; an estimation part being provided to the server, and estimating user's action information indicating that the user did actually on the area of the Wi-Fi sensor of the unit ID based on the part of the flow line and the flow time; and an analysis part being provided to the server, and analyzing user's attribute information including user's preference based on the estimated user's action information and installation attribute information indicating an attribute of an installation of the Wi-Fi sensor, the installation attribute information pre-provided to the unit ID of the Wi-Fi sensor.
