1. A wireless transfer device, comprising:

  • a memory storing instructions;

    one or more processors configured to execute the instructions to;

    determine a transfer band for a packet signal transmitted to a wireless transfer path, on the basis of a result of a comparison of communication quality information pertaining to wireless communication, and a predetermined band control threshold value which is a standard for changing the transfer band;

    determine a modulation scheme to be applied to the wireless transfer path, on the basis of a result of a comparison of the communication quality information and a predetermined modulation control threshold value which is a standard for changing the modulation scheme;

    secure the determined transfer band in the wireless transfer path, and output the packet signal; and

    perform a modulation process on the packet signal, on the basis of the determined modulation scheme,wherein the band control threshold value and the modulation control threshold value are set to be different values, to create a time lag between an operation for changing the transfer band and an operation for changing wireless transfer capacity of the wireless transfer path, the wireless transfer capacity being changed in conjunction with the changing of the modulation scheme.
