The A-MPDU TX retransmission rate is always high (> 20%) even in a very clean environment. However, the vendor driver retransimission rate is < 10% in the same test bed. The difference is the vendor driver starts the A-MPDU TXOP with initial RTS/CTS handshake which is observed in the air capture and the TX descriptor. Since the driver does not know how many frames will be aggregated and the estimated duration, forcing the RTS/CTS protection for A-MPDU helps to lower the retransmission rate from > 20% to ~12% in the same test setup with the vendor driver.
