Patent ID: 10878397

Abstract:
An order fulfillment system includes mobile terminals and a backend server. The mobile terminals generate, queue, and transmit state changes for orders in a restaurant, where the mobile terminals may communicate over both a Wi-Fi network and a White-Fi network. The backend server is operably coupled to the mobile terminals, and receives/transmits the state changes to all of the mobile terminals. The backend server has a queue processor, television whitespace (TVWS) band update logic, and a band assignment map. The queue processor is configured to queues the state changes in terminal queues. The TVWS band update logic periodically receives TVWS available channels for the White-Fi network, and assigns one of the TVWS available channels for communications over the White-Fi network. The band assignment map indicates whether each of the mobile terminals is programmed to communicate within the restaurant in the Wi-Fi mode or the White-Fi mode.
