摘要:
A transmitter/receiver 101 on a mobile body 10 utilizes a plurality of antennas 100. It is assumed that a plurality of the antennas 100 are distributed and arranged in a moving direction of the mobile body, and the antennas at both ends are away from each other at an extent that a distance between the antennas is not negligible as compared with an interval of the base station. A radio wave from the base station 102-1 is stronger in intensity in 100-1 than in the center, and the radio wave from the base station 102-2 is stronger in intensity in 100-2 than in the center, respectively, whereby the communication stabilization effect, which is larger as compared with the case that the antennas are locally located in the center, is expected. This enables the interval of the base station, which is broader than the conventional one, to be employed, yet both of a speed and a frequency of a hand-over process to be lowered, and in addition hereto, the bandwidth utilization efficiency, which is higher as compared with that of the conventional example, to be realized.
