    process a channel list response containing the specific channel access credentials and received in response to the detailed channel list request, including selecting an available channel specified in the channel list response for use in wireless communications; and

    generate and send a renewal request to the hub radio device to maintain valid use of the selected channel, the renewal request containing fewer data items than the detailed channel list request; and

    wherein the logical instructions further configure the spoke radio device to process a renewal reply received from the hub radio device, the renewal reply being;

    an acknowledgment reply that does not contain channel availability data if the selected channel is still available for use by the spoke radio device, in which case the spoke radio device continues wireless communications using the selected channel;
