Abstract: A wireless relay device for relaying packets via a wireless network includes an aggregator and a transfer controller. The aggregator is configured to aggregate a plurality of sets of data respectively included in a plurality of first packets transmitted from a plurality of wireless devices in the wireless network and under the wireless relay device to generate a second packet. The plurality of first packets is addressed to the wireless relay device. The transfer controller is configured to transfer the second packet to a transfer destination.
