In a repeater device: a communication device receives position information of a forwarding source device and a forwarding destination device using a first communication scheme; based on the position information of the forwarding source device, a moving mechanism moves the repeater device to a position at which it is capable of communicating with the forwarding source device using a second communication scheme; the communication device receives data from the forwarding source device using the second communication scheme; a storage device stores the data; based on the position information of the forwarding destination device received by the communication device, the moving mechanism moves the repeater device to a position at which it is capable of communicating with the forwarding destination device using the second communication scheme, and the communication device transmits the data stored in the storage device to the forwarding destination device using the second communication scheme.
