COMMUNICATION DEVICE AND METHOD FOR COMMUNICATION CONTROL, AND MACHINE AND SYSTEM FOR GAME

摘要

PROBLEM TO BE SOLVED: To provide a technique for realizing frequency hopping with superior real-time property in environment in which a plurality of masters are present.

SOLUTION: A game machine 20 is equipped with a plurality of communication modules 24 which perform frequency hopping and a control part 22 which controls communication by using the communication modules 24. The control part 22 controls frequency hopping of at least one of the communication modules 24 so that frequency channels that the plurality of communication modules 24 use do not overlap temporally. As a method therefor, for example, a frequency band is divided and divided bands may be assigned to the respective communication modules 24. Further, each communication module 24 may shift the phase of the same reference hopping pattern and use it or add a specified offset to the reference hopping pattern and use it.
