Classification: CPC H | IPC H

Claim 7:
8. An apparatus implemented as a physical machine, the apparatus comprising:
a device interface circuit configured for detecting link layer transmission of a wireless data unit between a wireless access point (AP) device and a wireless client device on a first allocated channel at a first transmission interval in a wireless data network; and
a processor circuit configured for causing the device interface circuit to transmit, based on detecting the link layer transmission, the wireless data unit at a second transmission interval on a second allocated frequency channel that is allocated to the apparatus for a mirror transmission between the wireless AP device and the wireless client device at the second transmission interval,
wherein the processor circuit is configured for causing transmission of the wireless data unit based on a determined absence of an acknowledgment indicating reception by the wireless AP device of the wireless data unit, and wherein:
the device interface circuit is configured for receiving a second wireless data unit on a corresponding third allocated frequency channel during the first transmission interval;
the processor circuit is configured for determining the second wireless data unit is received by the wireless AP device;
the processor circuit is configured for encoding the wireless data unit with the second wireless data unit; and
the processor circuit is configured for causing the device interface circuit to transmit the wireless data unit based on encoding the wireless data unit with the second wireless data unit, enabling the wireless AP device to recover the wireless data unit based on the reception of the second wireless data unit by the wireless AP device.
