ABSTRACT:
A data communication system has a first communication equipment having a first transmitter, a first receiver, and a first controller. A second communication equipment has a second transmitter, a second receiver, and a second controller. The first transmitter transmits a first signal to the second receiver. The first receiver receives a second signal transmitted from the second transmitter. The second signal indicates whether or not the second receiver received the first signal or indicates a condition in which the second receiver received the first signal. The first controller controls the first transmitter to reduce its transmitting power either until when the second signal indicates that the condition of the reception of the first signal received by the second communication equipment is poor or until when the first receiver does not receive any signal from the second transmitter. The second controller generates the second signal in accordance with the first signal.
