1. A communication system that is equipped with an access point and a plurality of stations to carry out periodic communication among them by setting a constant reference cycle as one cycle and setting a communication period of N cycle to transmit data, where N is a natural number larger than 2, and each access point and each station has a wireless communication device:
wherein the communication system has one normal transmission period in which a first transmission of the data is performed and (N−1) of retransmission periods to retransmit data that resulted in a communication error in the normal transmission period, and
wherein the normal transmission period of a next communication period overlaps the retransmission period of a previous communication period and successive N cycle communication periods overlap in a period of M cycle that is shorter than the N cycle, where M is a natural number smaller than N.
