<p>PROBLEM TO BE SOLVED: To provide the data communication equipment with an excellent communication efficiency in which collision of data is less by calculating and utilizing a medium reservation time. SOLUTION: The data communication equipment is made up of a radio LAN adaptor 36, a host computer 38, and an antenna 26 or the like. A data communication time from the data communication equipment to an external communication equipment and a data communication time from the external communication equipment to the data communication equipment conducted after data communication are calculated by a medium reservation time and the calculated medium reservation time is informed to the external communication equipment. Since the medium reservation time is reserved by this processing, the data communication efficiency is improved and data collision is reduced.</p> |
