PURPOSE:To provide a mobile object communication equipment which can be easily used like a radio pager, etc., to send the information to a receiver from a transmitter, to confirm a fact that the receiver has received the information, and also to confirm the location of the receiver, i.e., the useful information to the transmitter. CONSTITUTION:A fixed transmitter-receiver 10 includes the input/output terminals 11 where the call data are supplied and the transmitter/receiver stations 13 which are set at plural positions to receive the call data. Meanwhile a mobile transmitter-receiver 20 outputs a ringing tone and a message after reception of the call data and also transmits a reception confirmation signal. Each station 13 is constructed so as to receive the reception confirmation signal from the transmitter-receiver 20. Meanwhile each terminal 11 is constructed so as to output the position of the transmitter-receiver 20 that is specified by the installed position of the station 13 which received the reception confirmation signal or by the intensity of the radio wave of the reception conforming signal as the position data. |
