Abstract:
1. A wireless communication terminal in which a radio frame whose message type is “data” and a radio frame whose message type is “reception response” are present when the radio frame whose message type is “data” is assumed to be a data frame and a radio frame whose message type is “reception response” is assumed to be an ACK frame, an interval during which a data frame cannot be transmitted to a counterpart device after transmitting a radio frame to the counterpart device for wireless communication or after receiving a radio frame from the counterpart device is defined as a frame transmission interval, a frame transmission interval (IFSh) for a host and a frame transmission interval (IFSt) for a target are defined for the frame transmission interval and in the frame transmission interval, the frame transmission interval (IFSh) for a host is defined as being shorter than the frame transmission interval (IFSt) for a target, the wireless communication terminal comprising: an instruction unit (CPU) which instructs whether the wireless communication serves as a host or a target; a wireless communication unit which when being instructed to serve as a host from the instruction unit, transmits or receives the radio frame to or from a terminal serving as a target, and when being instructed to serve as a target from the instruction unit, transmits or receives the radio frame to or from a terminal serving as a host; and a setting unit which sets as the frame transmission interval, the frame transmission interval for a host when being instructed to serve as a host from the instruction unit or the frame transmission interval for a target when being instructed to serve as a target, and changes the frame transmission interval to a frame transmission interval equal to or longer than the frame transmission interval for a target when the frame transmission interval for a host is set, or changes the frame transmission interval to a frame transmission interval equal to or shorter than the frame transmission interval for a host when the frame transmission interval for a target is set.
