PURPOSE:To flexibly cope with environmental changes without losing any characteristics by allowing one node to check the strength of received radio waves from an opposite side node, informing the opposite side of it and controlling the transmission output of the opposite side node based on this information. CONSTITUTION:A receiving part 1 of each computer terminal 101 (102) is a module to perform reception control as a computer terminal to perform data communication with radio waves as media and is equipped with a received signal strength detecting part 1a. When there is a radio link establishing request from a radio link establishing request source node, at a radio link establishing request destination node, the detecting part 1a detects the received signal strength of those requested radio waves. Then, the received signal strength is informed for the request source node by a signal strength informing part 2a. Therefore, a radio transmission output control part 3 controls transmission radio wave outputs to the request destination according to a signal strength informing signal from the request destination node at the request source node. Thus, in the case of following data communication, the transmission radio wave output can be lowered without degrading transmission quality. |
