PROBLEM TO BE SOLVED: To enable communication from an arbitrary transmitter only to a specified receiver within the same frequency by arbitrarily setting the ID numbers of digital switches or the like mounted on the transmitter and the receiver. SOLUTION: This wireless transmission-reception system 1 is composed of a transmitter 2 and a receiver 3. Each time a transmission switch A is turned on, the transmitter 2 outputs the carrier burst modulated high frequency signal of a pulse number set as the ID number by a pulse setting means D for setting the number of pulses to be generated from a pulse generating means B. Besides, only when the ID number preset by a comparative value setting means H for arbitrarily setting the comparative set value of a counting/comparing means is coincident with the number of pulses of a received signal, the receiver 3 outputs an output signal G and drives an alarm or display means. The operation for setting the ID number can be easily performed by the digital switch or the like and there is no trouble in the operation for setting the ID number for each group or each member in the group.
