Title: LOCATION DETERMINATION SYSTEM
Abstract:
This location determination system is provided with: in-vehicle equipment (10) which is mounted in a vehicle; and a mobile terminal (20) which is a communication terminal carried by a user in the vehicle, and is configured to transmit a radio signal including transmission source information at least once within a prescribed time. The in-vehicle equipment is provided with: receiving units (140, 150, 160) which receive, through an antenna installed in the vehicle, the radio signal transmitted from the mobile terminal and detect the reception intensity of the received radio signal; and a location determination unit (F6) which determines, on the basis of the reception intensity of the radio signal detected by the receiving units, whether the mobile terminal is present within a preset target area from the installation location of the antenna.
