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.

Abstract: A wireless relay device for relaying encrypted data via a wireless network according to one aspect of the present invention includes a relay controller and an encryption processor. The relay controller is configured to relay a first data to a predetermined relay destination as a second data via the wireless network. The first data is transmitted to the wireless relay device via the wireless network and is addressed to the wireless relay device. The encryption processor is configured to decrypt the first data into a decrypted first data and to input the decrypted first data into the relay controller, and encrypt the second data to be relayed by the relay controller.
