<p>PROBLEM TO BE SOLVED: To provide a data transmission system by which data transmission time is shortened at a low cost. SOLUTION: When a terminal device 20 receives polling data retransmitted from a repeater 30d, the device 20 constructs a data frame and transmits the data frame. In such a case, the device 20 transmits the data frame in prescribed sequence. The sequence of the data frame transmitted by the device 20 is decided by setting B in a B frame time timer 209 and N in an N counter 210. When the B=1 and the N=7 are defined, the device 20 repeats an intermittent frame transmission operation in which one frame time transmission operation is stopped after transmitting one frame until the transmission of seven frames is over.</p> |
