Abstract: The objective of the present invention is to control a beacon in a mesh beacon. A system contains a plurality of beacons which are capable of communicating with one another within a prescribed radio wave reaching distance and which transmit and receive prescribed signals, each of the plurality of beacons being disposed within the radio wave reaching distance of at least one other beacon, and a control device capable of communicating with at least one of the plurality of beacons. Each beacon is provided with: a receiving unit for receiving a signal including a setting change instruction sent from the control device; a setting unit for changing the setting value of a prescribed item in the device on the basis of the setting change instruction; and a transmitting unit for transmitting a signal including information based on the setting value changed by the setting means to the control device.

Abstract: In a position calculating method performed by a system including beacons, and a control device capable of communicating with the beacons: at least one of the plurality of beacons receives, from a terminal present in the radio wave reaching distance of the beacon, a first signal including terminal identification information identifying the terminal, measures the reception strength of the received signal, and transmits a second signal which includes the terminal identification information, the reception strength and beacon identification information identifying the beacon; and the control device receives the second signal from one of the plurality of beacons, and, on the basis of the position information of the beacon corresponding to the beacon identification information included in the second signal, and on the basis of the reception strength included in the second signal, calculates the position of the terminal corresponding to the terminal identification information included in the second signal.
