<p><P>PROBLEM TO BE SOLVED: To provide a packet communication system, dependent upon radio, in which when determining a suitable frame length for obtaining excellent transmission property, the suitable frame length is not determined by inference due to an observer or the like who is monitoring a communication status, but the suitable frame length can be automatically determined. <P>SOLUTION: A packet communication system dependent upon radio includes: a means for determining a threshold of a reception field strength with which a frame can be normally received; a time measuring means for determining the time during which the reception field strength equal to or higher than the threshold can be continuously held; and a means for determining a frame length on the basis of the time during which the reception field strength equal to or higher than the threshold can be continuously held. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
