<P>PROBLEM TO BE SOLVED: To perform signal distribution, signal switching, and signal concentration by simple configuration. <P>SOLUTION: A signal transmitter comprise: a transmission path coupling part 108 (transmission part) which transmits a transmission object signal as a radio signal; a transmission path coupling part 208 (receiving part) which receives the radio signal transmitted from the transmission part. Multiple pairs of the transmission position of the radio signal in the transmission part and the receiving position of the radio signal in the receiving part can be formed. Using the multiple pairs of the transmission position and the receiving position, at least one of signal distribution by which the same transmission object signal transmitted from the transmission position is transmitted to multiple receiving positions and signal switching by which the transmission object signal transmitted from the transmission position is selectively transmitted to either of the multiple receiving positions can be executed. The transmission object signal is transmitted as a radio signal. Then, signal distribution or signal switching is achieved at a part of the radio signal. Since no part to perform signal transmission by electrical wiring is included in the part to achieve signal distribution or signal switching, signal distribution or signal switching or signal concentration can be performed by simple configuration. <P>COPYRIGHT: (C)2012,JPO&INPIT |
