Wireless communication system, fixed base station and mobile terminal station

A base station for wireless communication with a terminal station carried by a vehicle entering a communication area thereof, wherein:

• the base station is separated from adjacent ones by a predetermined distance along a traveling route of the vehicle;
• and
• the communication area of the base station is sized to cover generally only one vehicle to exist therein and the communication area is separated from communication areas of adjacent communication areas without overlapping.

A terminal station carried by a vehicle for wireless communication with a plurality of base stations separated from each other by a predetermined distance along a traveling route of the vehicle and capable of divisionally receiving given data from the plurality of base stations, the terminal station comprising:

• data storage means for accumulating the data transmitted divisionally from the base stations,
• wherein the data storage means has a data storage capacity which is more than a value R×T which is a product of R and T, R representing a data rate used for transmission of the data at the terminal station and T (=L/v) representing non-data transmission time determined by a velocity v at which the terminal station moves between adjacent communication areas divisionally transmitting the data and the distance L between the adjacent communication areas.

A terminal station carried by a vehicle for wireless communication with base stations separated from each other by a predetermined distance along a traveling route of the vehicle, the terminal station comprising:

• an antenna for transmitting a carrier wave which forms a communication area from approximately right above a traveling course of the vehicle,
• wherein the antenna is mounted in the upper part of the vehicle.
