A communication system includes a center station communication device and a plurality of local station communication devices. The center station communication device includes a transmission unit which transmits first data including reference information to the local station communication devices, the reference information being used for switching the local station communication devices from an active state to a waiting state for a period of one-to-many communication in which the center station communication device transmits second data to the local station communication devices. Each of the local station communication devices includes a receiving unit receiving the first data and the second data from the center station communication device and a state switching unit which, for the period of one-to-many communication, switches from the active state to the standby state based on the reference information. |
