Abstract:
A mobile communication system is provided which serves as an information infrastructure capable of providing intelligent information transmission and services. A mobile station on each vehicle traveling on a road includes first and second transceivers for carrying out radio communications with a third transceiver of a base station installed on a roadside. The first transceiver of a first mobile station is linked not only with the third transceiver of the base station through a first communication channel, but is also linked with the second transceiver of a second mobile station via a second communication channel. The first mobile station carries out information communications with the base station using the first communication channel, and at the same time with the second mobile station via the second communication channel. The first, second and third transceivers each have the function of measuring the incoming direction of the radio wave from the party, and calculating the distance to the party so that the location of each mobile station is identified in each station.
