Improving data flow in long-distance 802.11 bridge links involves optimizing the communication process to reduce the likelihood of data packet retries, which are often caused by increased latency and signal degradation over distance. The acknowledgment timeout threshold is crucial in this context.

Setting an appropriate acknowledgment timeout threshold means that the sender waits a specific duration for an acknowledgment (ACK) from the receiver before attempting to resend the data. In long-distance transmissions, the time it takes for a signal to travel back and forth can be significantly longer. If the acknowledgement timeout is set too short, the sender might prematurely assume that the transmission has failed and trigger a retry, even if the packet is still in transit.

By carefully adjusting this threshold, operators can ensure a more effective use of the available link, allowing the sender to wait longer for an ACK before considering the transmission unsuccessful. This way, the chances of unnecessary retries due to distance-induced delays are minimized, improving overall throughput and data flow on the bridge link.

Other parameters, such as sequence control field or minimum transmit data rate, while relevant in various contexts, do not directly address the timing and delay issues intrinsic to long-distance communication. Similarly, the CTS-to-self threshold involves mechanisms to avoid collisions but does not specifically mitigate the
