The present invention provides a first gateway that can receive, buffer and acknowledge a number of files from a data terminal. The gateway can then transmit one or more first segments derived from the received files to a wireless device over a first wireless link. In the event that the first wireless link is broken, any data not received by the wireless device by the first gateway can be provided to a second gateway. The second gateway, in turn, can provide the remaining data to the wireless device using one or more second segments without requiring that the second gateway contact the data terminal.
