Redundancy control for data traffic through a wireless link

A device (150) is arranged on a source side of a wireless link (50) and receives data traffic from one or more source devices (201, 202, 203). The device (150) forwards the data traffic via the wireless link (50) and via a further device (11), which is arranged on a destination side of the wireless link (50), towards one or more destination devices (21, 22, 23, 24). The device (150) receives redundancy information from the further device (11). The redundancy information indicates redundant payload which is common to multiple data frames in the data traffic forwarded by the device (150). Based on the redundancy information, the device (150) removes the indicated redundant payload from at least a part of the data traffic to be forwarded by the device (150).
