<p>When relaying data between devices at distant locations by using a single frequency, a relay device interposed in the middle of a transmission section can accommodate newly-added terminals, so that limitation on connection of the relay device can be relieved. Specifically, it is configured to include a master 10, REPs 20 and 30 that are connected to the master 10 by a time division multiple access and relay data from or to the master 10 by using a signal of a single frequency (frequency F1), and slaves 21, 22, and 31 to 33 that are connected to the REPs 20 and 30. The REPs 20 and 30 are configured to operates as a master for the slaves 21, 22, and 31 to 33.</p> |
