One wireless controller inside a source device is selected in order to perform link communication while other wireless controller(s), not selected, is/are configured in a specific mode, called mirror mode in which physical transmission of data frame(s) over the medium is disabled. The selected controller is configured into a transmission mode also called normal mode in which physical transmission of data frame(s) over the medium is enabled. Data frame(s) to be transmitted are stored in buffers for both the normal and mirror mode before transmission. During the wireless communication, the wireless controllers are controlled and switched over the time from normal mode to mirror mode by a link controller. The link controller advantageously selects the most effective wireless controller(s) for the transmission of data frame(s). The mirror buffer is updated based on a virtual reception acknowledgement determined from a reception acknowledgment to ensure all buffers content is identical. Accordingly, a swap between the wireless controllers may be carried out without disturbing a real time transmission. |
