TRANSMISSION SYSTEM
Document Type and Number:
Japanese Patent JP2016082513
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To converge the propagation region of radio wave signal, transmitted from a radio wave transmission device, by a compact structure, in a transmission system including a plurality of radio wave transmission devices for transmitting radio wave signals.SOLUTION: A transmission system includes a plurality of radio wave transmission devices and a plurality of radio wave propagation region restriction devices, installed corresponding to the plurality of radio wave transmission devices, respectively. The plurality of radio wave transmission devices transmit radio wave signals, respectively. The plurality of radio wave propagation region restriction devices restrict the propagation region of radio wave signals, transmitted from a corresponding radio wave transmission device, to a predetermined range. Consequently, the propagation region of radio wave signals transmitted from a corresponding radio wave transmission device, and the propagation region of radio wave signals transmitted from other radio wave transmission device are restricted to the ranges not overlapping.SELECTED DRAWING: Figure 1
