Perhaps there are some parameters to enable the "block ACK" or other useful options to decrease the waiting time or the hw-retries setting even at the cost of packet losses?
802.11ad are standardizing 60 GHz technology to facilitate multi-gigabit-per-second
communications over shorter distances. This standard has many new features to improve and
sustain high-speed communications with TDMA single-carrier and OFDM schemes. They allow
for scheduled and contention-based access, beamforming, and power-save mechanisms that
decrease power consumption and increase throughput...
802.11ad defines a frame acknowledgement (ACK) policy called block acknowledgement.
When block ACK is enabled, the transmitting station transmits a block of frames one frame at a
time immediately after each other without waiting for the receiver to acknowledge the
previous frame. After the entire block of frames has been transmitted, the receiving station
sends a control frame called block ACK that includes a bitmap. The bitmap, in which each bit
corresponds to a frame, indicates which frames were received successfully and which ones
were not. The receiver knows to send a block ACK frame when it receives a block ACK request
frame from the transmitter. This ACK policy allows the transmitter to use shorter IFS between
frames, and it eliminates the IFS between each frame and its individual ACK frame, as in a
typical stop-and-wait protocol...
