[Problem] To prevent either of two packet data having the same content from being affected by noise

[Solution] A packet data transmission device (not shown) transmits first packet data 1A, . . . and second packet data 1B, . . . having the same content intermittently with an idle time I therebetween. When the length of the first and second packet data 1A, . . . , 1B, . . . is denoted by L.sub.P, the length of the idle time I is denoted by L.sub.I, the duration of low-frequency noise N is denoted by L.sub.N, the time with no low-frequency noise from the occurrence of one low-frequency noise N to the occurrence of the next low-frequency noise N is denoted by L.sub.C, the following expressions (1), (2) are satisfied. Consequently, either the first packet data or the second packet data is transmitted to a receiver without being affected by noise.
