Abstract
A radio communication system, in which radio communication is carried out between an in-vehicle communication device, mounted in a vehicle, and a radio communication terminal to detect a relative distance therebetween, includes an output control unit that controls a radio wave intensity of a measuring signal, which is sent from one of the in-vehicle communication device and the radio communication terminal, at a pre-set predetermined value; and a measuring unit that performs distance measuring on a vehicle side based on the radio wave intensity of the measuring signal controlled at the predetermined value or on a signal to which a value of the radio wave intensity of the measuring signal is added as information.
